Citrix DaaS (formerly Citrix Virtual Apps and Desktops service) Reviews

LG Uplus is using Citrix for internal groupware. Every employee here uses Citrix to access the VDI to make some Word documents or PowerPoint presentations. We are not allowed to use our local PC resources at all. 

The second use for my team's project is that we are reviewing the potential for a virtualization solution for our customers, who are mainly video editors. We offer them a low-price alternative. Instead of buying our high-end desktops or workstations, they can save money by virtualizing some application solutions. 

This is deployed in LG CNS, which is a subsidiary of the LG group. Most LF subsidiary companies are a part of the LG CNS solution. LG CNS solution is combined with Citrix, which means that if you work with LG CNS, you have no choice but to use Citrix.

First, since we adopted the Citrix VDI, we are no longer dealing with the problem of leaking the customer's personal information. Second, we aren't investing a lot of money in buying new personal laptops. With the VDI, we aren't relying on a high-core CPU or memory in each employee's laptop. Because the functions that require a lot of memory and CPU are happening in the cloud, we can just give the employee a basic Pentium CPU laptop.

The Virtual Desktop Interface is very important because we have many departments for customer service. For example, we have operational storage and also we have a customer call center. Most of the customers are calling about a security problem. 

Before we adopted a VDI storage solution, our customers' personal information was leaked. This happened a lot. But since we adopted a VDI solution, these kinds of issues have happened rarely. Of course, we banned each user from installing or sharing software, like peer-to-peer sharing software. There is no chance that a single user could leak personal information by mistake through unauthorized access.

Virtualized solutions are very important. Because of the high-speed internet service here, I think the virtualization application solution can be adopted in a B2C market for customer service.

We've tested a lot of cases with the Citrix solution and found that it's okay when the Citrix virtualized solution is adopted over the laptop or desktop. But it has some latency issues—a lag between the input device and screen—when we test it with a smartphone or tablet. The reason that users use the virtualized desktop is they want to access a Windows 10 application, but they need their keyboard and mouse. Every employee complains about the performance or quality of their VDI. After we adopted the security solution, I think the performance is quite better. But employees are still complaining about the speed of the VDI.

Latency is also a major problem when adopting Citrix for video editing software or 3D editing software, especially editing 4K video or large file size. The Citrix virtualized solution becomes too slow, so we cannot use the VDI. For the streaming, Citrix needs to improve its screen resolution problems because this is a market trend. We produce and use a lot of high-density videos. If Citrix cannot improve these kinds of issues, then we might not be able to use VDI anymore two or three years from now.

Citrix doesn't offer any solutions for the virtualization of macOS, either. I think we could use that kind of service.

It's been around 10 years or so.

I would rate it very low actually. Because here in Korea, most of them are for sales, not technical assistance. For developing some applications, we have to choose or test virtualized applications. But call up Citrix agencies—sales agencies—they say they cannot solve the technical issues. We have to find some technical references through the internet or through developers who have some experience with Citrix.

Internally, the IT department uses Citrix. For developing customer service for my team's product, I use Hyper-V's client solution instead of Citrix, because the price of the Citrix virtualized application solution is too high. Citrix only provides the B2B license here, so they don't have any B2C license. I use Hyper-V-based applications and virtualized solutions because of the price issues.

I think it was very complex. It was difficult to install Citrix by ourselves, but we have an IT department and a PC maintenance department. The initial setup required around three people. But after the initial deployment, most employees don't have any trouble with installing Citrix solutions. For each user, it takes around half an hour. For example, I broke my laptop and had to get a new laptop. I personally asked the IT and PC maintenance departments to install the systems again. It took them around 30 minutes.

We have a dedicated IT department. They have a contract with Citrix and they're employed here. 

It's tough to say whether we've really seen any cost savings. Many people don't believe the Citrix solution lowered the total cost of the whole system. But I think if we adopt an application virtualizing service, then we can reduce costs a little bit more. 

Currently, everyone here is using the same public cloud server resources for every software. but if we adopt a virtualized application solution, then the IT department can choose which software needs a lot of resources and which can adopt lower-tier public cloud resources. That way, we can save a lot of infrastructure costs.

It's my understanding that the solution license fee for each user is around $300 US. If we buy a personal laptop for each employee every five years, then the total cost is five times $300 US, or $1,500 USD. So we could buy 100 personal laptops instead of the Citrix solution. If we compare the cost of a high-performance laptop and the price of the Citrix solution, the total cost savings is very small. But we can improve the security issue.

I think the speed and latency of Hyper-V are quite good, but one thing I worry about is the security issues. Our internally developed client for the Hyper-V solution doesn't have as many security solutions as Citrix does. As I recall, LG CNS has its own VDI solution. At this moment, there are some solutions that can replace Citrix, like FreeVDI, an open-source VDI, for example. We have tried using those kinds of service solutions in some departments, but they didn't quite meet our expectations.

I would rate Citrix seven out of 10.

In the beginning, the Citrix Virtual Apps and Desktops was designed for our COVID-19 business continuity plan. We use a lot of Citrix Desktops (for around 600 people). The desktop was built for out of office work, whitelisting clients, for all work done with a personal computer, and for the business continuity in a white room with dedicated computers. Today, we have changed the total design using enterprise laptops for everybody, so the desktop is gone and we only publish applications for end users.

The profile between the Citrix published applications and the broker profile on the laptop is permitted to use the same profile and the same settings for the user in Citrix and the laptop. It is a mix of both environments.

We are deployed in two parts: Belgium and Luxembourg. In Belgium, we have around 20 sessions concurrently, which are 100 percent deployed on-premise. In Luxemburg, we have around 400 sessions concurrently.

Today, we use only Citrix Virtual Apps and Desktops. In the past, we also used Citrix Gateway to bring Citrix on a government forum or working with a personal computer, though this part is totally void today.

While we use it on-premise, we are using it more and more for cloud applications and infrastructure. Workers run applications on-prem to segregate correctly the access rights. All our tasks are on-premise, which is a positive for our security and the regulatory authority.

There was a scenario where a user built very small films for internal communication on his laptop via the VPN using the NAS file system. It's not the best solution. This takes around 45 minutes. With this use case, we installed all the tools on Citrix. Now, the user can build his film in a maximum of two minutes. It was an incredible improvement for the user. Today, this is the best case of Citrix usage for end user experience, using the full capabilities of the server in the data center.

Our organization supports Zero Trust as a security strategy. However, the Zero Trust strategy in the bank is done via the VPN. Also, all laptops connected out of the bank are via VPN. We don't use the full Citrix landscape to do this today.

For all applications in the bank, we set up Active Directory groups to have access rights. All users can access a lot of applications, but the rights are given one by one for each application. Therefore, it's very centralized at the Active Directory level.

The business continuity plan was 100 percent based on Citrix and the client. Today, it is a little different because everybody has a laptop, but the main applications are still available on Citrix. This offers the more flexible possibilities of managing business continuity plans and performance everywhere for end users.

In Luxembourg, a user can use business applications with Citrix inside the building. Then, outside the building, that user cannot use the business applications because we cut the usage of Citrix.

We can provide tons of applications with different settings, behaviors, and operating systems. It is the same way for the user. Then, we are totally transparent for the user to use a lot of totally different applications, which is the most important part of Citrix today.

Remotely, the user can use his personal computer with a VPN to the bank, as there is not always WiFi. We have seen very low boundaries in some cases. With the Citrix application, we provide very beautiful applications. We are running without a lot of resources in the data center and the user doesn't see it. It's totally transparent for them.

In the bank, a major part of all our applications is Microsoft App-V. If App-V is at end of life, then we need a new technology to replace it. As of today, I haven't seen in Citrix Studio that there is a new technology embedded directly in it to replace App-V.

We have been using Citrix Virtual Apps and Desktops for more than 10 years. We started with a full complement of Citrix features, but today we only use a small portion of it. This changed over the years. 

The stability of the solution is great. It is not evident to me whether the lack of stability is linked with the new data center, due to a Citrix issue or new component in the new data center. However, in the past, Citrix was very stable. 

In the beginning, we had more than 70 users with only one reboot per week. I have heard that some companies rebooted every day at night. For us, that was not mandatory. The solution has been very stable with the condition that our applications are packaged correctly.

We plan to migrate to the latest LTSR version next year.

The scalability of Citrix is incredible because we use the Provisioning Services (PVS) solution. With this technology, the same image can be streamed to all servers. With this technology, I don't need to install, reinstall, nor repackage it. 

Globally, we have 600 to 700 users with Citrix access in the company. Their roles of Citrix users are private banker, operations, and sales. 

There is not so much support because the solution is very stable. However, we use Citrix ShareFile, and for this, all calls are solved within five hours. Citrix is very good for our usage today, and we haven't had a big issue.

We have been using Citrix for a long time. Building and first implementing Citrix was a little complex. We have a lot of components. However, when you manage all of them correctly, then it's easy. 

The first time, it was a little complicated to build the first images. Today, with versions, this is easy. We built a new image in four hours, which is incredible. Over time, we have improved the function and management of Citrix.

Implementation in the bank was in three steps: 

1. We implemented it in a test environment, like a beta environment, with a beta tester and system engineer to improve the solution and application, then checked everything was working. 
2. In the acceptance environment, we set up all the same settings as production. We asked key users to validate everything: applications and behaviors. 
3. We copied-pasted this environment (if everything was okay) into production for end users and key users. It had totally the same environment with the same behavior. Then, we validated all the environments from acceptance to production directly on the same Citrix environment. 

Acceptance and production are only one big environment where acceptance and production workers cohabit in separate tools and where all users can go into the acceptance or production environments by default. When we validate a new disk or function in a new application, we go to acceptance with just an Active Directory group to validate the solution. This is really great.

In the beginning, we used a partner as an integrator to help us design the Citrix and implement the first part. We have been using a partner for maintenance and upgrades because we don't have the knowledge at this moment about the newest version of Citrix. 

As partners, we used Acidos to build our first version, then we used SecureLink. However, I don't think the Citrix partner aspect of SecureLink's company exists anymore.

We deployed the first bit with our partner. We did this with seven or eight system engineers to build and go through tests. That was the first version. Today, for Belgium and Luxembourg, we have only three system engineers to maintain and publish new applications.

With Citrix, we saved a lot in the past for the business continuity plan. Today, it is not so much, but we still make money because the performance is there.

If you look at cost, then you must look at the number of users that you are covering. If you are only using it for some users, then it is very expensive. However, if you have a massive amount of users, then it begins to be interesting to use Citrix. Because once you are managing thousands of servers with one guy, your maintenance costs decrease per user.

Another major cost is Microsoft because Microsoft Windows costs them. We also need a license for SQL server, Windows Server, and Citrix Remote PC. These are extra costs for the solution that are not covered by the license.

We haven't evaluated similar solutions. We don't have any other solutions for replacing the Citrix Virtual Apps and Desktop. Therefore, I think we will stay with Citrix for a long time.

We use other tools for analysis, not the Citrix tools and analytics. We don't use the Citrix tools because all our firewalls are not Citrix Firewalls.

All our detection and monitoring are not done via the Citrix environment because we have other tools for that.

There has been a lot of improvement in the application. We use the application for so many different things and areas of security. It is incredible what we can do with Citrix. It provides total transparency for us.

Today, it does not provide the flexibility of being used on any device because we use it on enterprise laptops. However, in the past, users could use their personal computer. It covered a lot of models and brands, and it was totally transparent for us. We only asked, "Please install Citrix receivers," then the rest is transparent for the system engineer. 

It is not clear for this moment if we will increase the usage of Citrix, because we don't know where the user will be working going forward (at the office, home, or another country).

I would rate it an eight out of 10. It's not only Virtual Apps and Desktops. Also, other products that I see from Citrix on the market are good. They look for the best performance solution for the end user.

We deliver mainly desktops to all of our offices, using thin clients. Since we've been working from home during the pandemic, people just use their home computers to access their desktops. We deploy a desktop full of a standard set of applications, and we have a few published applications that are not on a desktop. People access those from that desktop, and some people access them as a published application and not a desktop.

We have people who have laptops and some of them just use one or two applications, so they don't get a full desktop. They'll just VPN from their laptop and use Citrix to access those few applications.

The following represent how Citrix technology is leveraged in our organization: application virtualization capabilities, on-premise desktop virtualization, and Remote PC access or remote access to physical desktops. We don't do the latter a lot, but we do publish remote desktop as a published application. Some use remote desktop to get back to their machines. We don't use the remote PC functionality. I wish we did, personally, but those are decisions that unfortunately get made elsewhere, and RDP was chosen versus publishing them as an ICA app to people.

Citrix Virtual Apps and Desktops provides the flexibility of being used on any device, which makes it easier to work for many anywhere. The transition from people working in an office every day to working from home was seamless, for the most part for us, because almost everybody has a personal computer, whether it's a PC or a Mac. We had a lot of people go out and buy Chromebooks and any other type of device that they saw fit for themselves. They just logged in to our portal and launched their desktops, like they always would. It's very flexible.

The biggest benefit was when we had that transition when offices were closed due to the pandemic. We had thin clients in the offices, so people were already using Citrix whether they were in the office or not. The flexibility provided by that alone was invaluable, in just getting people able to work from home. That's what the product is supposed to do. We didn't really have work-from-as a model. People could do it, but it wasn't a big thing for us. It was more along the lines of when you were done for the day you went home, and if you had to log back in, you could. But for the most part, people were done with work until the next day.

Citrix also plays a part in our business continuity strategies. We have in-house applications and, since we have data centers in various regions, we need the ability for a given application to be live in other data centers, even though we only currently have it running from one. vSphere is the platform that we use for virtualization so we have infrastructure that's the same in every data center. We have a Citrix environment just for DR that we can copy our vDisks into, in Provisioning Services, from one data center to the next. We can then just spin up a Citrix desktop that has access to that DR environment. The other teams then spin up their pieces of infrastructure within that DR bubble and test it. Citrix gives people the ability to quickly get into that DR environment once it has been stood up.

Another aspect is that the solution has resulted in IT efficiencies because we can be pretty agile with quickly reverting changes and quickly implementing new changes. It provides a lot of flexibility for us.

The Provisioning Services are the most valuable feature. We have Premium licensing, so Provisioning Services is huge for us, along with the Virtual Apps and Desktops part. It allows us to have a vDisk for every region, one that can easily be copied between them if we need to, to limit the amount of updates we have to do. 

The ability to deploy shared, hosted desktops and published applications, is also important.

And I would rate the user experience, when using the solution’s technology remotely, as high as it can be. We have offices all over the world, and some of them are in areas that have absolutely terrible internet service. For users in those areas, while we do get complaints that the experience is bad, on most days it's tolerable, and that's even on the bad days when there is extremely high latency. Especially not knowing where people are going to be working from, I would say the user experience is very good.

When it comes to the solution’s centralized policy control, as in the policies you apply to ICA sessions and session hosts or virtual desktop agents, you can control those through group policy, in addition to group policy, or put them in from the console. But either way, as a central management point for the Citrix sessions, in general, it's very good. It gives us flexibility. For example, with the users who are in the bad internet service areas, those policies give us the flexibility to lower their user experience, to dim down the graphics and sound quality. We can do that on-the-fly when they report problems. That generally helps their experience a little bit. So the policy control is good.

And if you have the full line of Citrix products deployed—NetScaler, MAS, all of those items tied together—the visibility is second to none from a monitoring perspective. We use the NetScaler and the MAS and the data that comes through there is almost invaluable, if you have the licensing to use it.

In addition, the security of your intellectual property and data when remote employees are using Citrix, is very high because, with Citrix you can limit access to the local device and access to the network, so you can't copy files if you have certain policies set between the Citrix session and the endpoint. You can prevent printing. You can prevent any data from ever leaving that desktop. And if you're licensed for it, which we are not, they've recently added the ability to watermark screenshots and to have keylog protection in Citrix sessions. If you're licensed for it, that's just an added bonus to the security features that are built-in by default.

The version of Director we're on, the 1912 version, has improved some of the monitoring capabilities that went back to what EdgeSite used to be as a product, when it comes to real-time analytics. If anything could be improved, it might be some of the Director functionality, and some of the dashboard customization, or the overall Director customization. We're limited in what we do. We use Director, as administrators, more than the service desk does, and we limit their access to Director to a few screens. They don't even get to see the full scope of what we see in there. Director is one thing that could be improved upon.

I've been using Citrix Virtual Apps and Desktops for about 10 years. My first experience with any type of virtualization technology was with Citrix. My first helpdesk job was supporting a company that deployed Citrix applications specifically, not desktops. I started out doing it from a support perspective and then got into the administration and engineering side, at that same place. I've never worked on any other products like Citrix.

I would rate the stability very highly, as high as it can be, due to my long-term experience with the product and how it's evolved to the point that it's at. That rating is based on my firsthand knowledge and experience of seeing it used and implemented, day in and day out, not only here, but at other places I've been that are larger than where I am now. I have a high opinion of it in general. It's been my career choice to work specifically with Citrix products.

It scales very well. The limitations we face are our own hardware constraints, because we purchase what we need and we don't generally provide much overhead. Our scalability problems come from limitations on hardware purchases, probably due to budget. If our company doubled in size, we would not have a problem scaling what we have today to meet that. We could probably do it in a couple of days and be just as fine.

We're licensed for 3,000 users. Our primary usage is in the U.S. and the AMEA region. We have about 2,400 users in that region who are active on it at any given time. The rest of those licenses are used in the Asia Pacific region. They're not as active in Citrix because a lot of their stuff is not as centralized as our other infrastructure is. They still don't use a lot of the same stuff. But they do use Citrix for email and for a couple of other things.

We haven't used them recently, but I generally have a high opinion of Citrix technical support. They have the knowledge and give us access to the expertise. I've worked with them in the past on a lot of things and, in some instances, if not for working with them, some of the problems we faced wouldn't have been solved. We didn't have access to anyone else with that level of knowledge.

I just started here about a year ago, but I was involved in setting up the 1912 environment. The process was straightforward. While they've changed the product names over the years, the underlying architecture and the technology, for the most part, has remained the same. I know there have been technological advancements and changes in the underlying architecture, but the overall end result, and some of how it does things, has remained the same. The setup was very easy for me and I think it would be easy even for somebody who is slightly new to the product.

Our most recent deployment did not take long at all. The longest part of it was the formal requests to the other teams and having them provision the virtual machines that we requested for the infrastructure. The longest thing about the deployment for us is getting to the point where we're comfortable putting a desktop out there for user consumption. It's getting them to test and validate that we built that desktop the same as the current one they're using. It's not so much that the deployment takes long because of any Citrix product problems. It's more due to user acceptance testing of the functionality of the desktop itself and the software we use.

Four or five people are involved in deployment, between the ones on our team who build, install, and configure the various infrastructure pieces, and the people that we make requests to who build the database servers and the other virtual machines.

We deploy according to the best practices. We don't follow any specific guides, but we deploy with the minimum specs, plus what we know we need to scale for the user base that we have.

We did it ourselves.

Citrix provides everything in one integrated platform—even the lowest licensing version. It depends on your needs. But if you have the Premium Edition, it provides absolutely every tool you could need to virtualize and deploy.

I'm not involved with the licensing, purchasing, or cost-comparison types of discussions. I'm primarily on the technical side. But I would imagine the integrated platform plays a large part in providing value. Citrix is a leader in this space. Our company has to see some value in the product to pay for it as it is. I would always advocate for it over other similar products.

If you're looking at implementing it, plan as best you can at all levels. Citrix has its consulting methodology for how to properly plan and deploy an environment. I've been in a lot of places where I haven't seen the planning phase happening. Planning goes a long way towards a successful deployment, because you test a lot of things during the testing phase of that, in particular. You see things that you wouldn't otherwise see if you just built it and threw it out there and said, "Hey, use this." You would run into a lot of problems that you wouldn't understand, things that need to be tweaked for any deployment, no matter where you're deploying it. There is a set of standard things that you need to do. Planning goes a long way towards making sure that it's not only accepted by your end users but that it's supportable.

Access control comes into play because we have different Citrix environments for different regions and they don't really cross-talk. We do limit certain things to certain environments, or some things are only available from one environment. People from the other environments have to access it from a different environment, but to them it's seamless because they're all behind the same store-front environments.

We initially implemented it so that our attorneys had an option to work from home. The majority of them did not want to carry a laptop back and forth. Prior to 2020, we did have four of our 40 attorneys using it almost full-time on a work-from-home basis.

We use the following in protecting our environment: Citrix Gateway, Remote Desktop Access, Citrix Secure Browser, Web/URL Filtering, and Contextual Access.

It's amazing that if someone has a sick child, they can still work. It's not that they are completely dead in the water. They can log in and access 99 percent of what they need to, as if they were in the office, and the workflow is the same.

Our previous solution was Terminal Services and that had very low security. My only security concern with this solution is users saving their logins and passwords in the browser. The security it provides is relatively high. The built-in security of Citrix is leaps and bounds above what the basic Microsoft solution had. I did request we add two-factor authentication, but that has not yet been approved. My management feels that I am doing a disservice by trying to add security measures.

But something that makes our security easier is that Citrix provides access control based on device, location, end-user device, or application. One of the reasons we chose Citrix was because it was one of the more secure offerings for remote access. I have faith that Citrix will continue to have that.

In addition, when COVID hit and I maxed out my Citrix licensing, I used the automated analytics to try to ensure everything was running well. It was very nice to be able to log in and see that I wasn't exceeding any capacity of Citrix or the servers themselves.

It provides everything in one integrated platform, and most of it is on one dashboard, which makes it even better. Monetarily, Citrix is a mid-range cost solution compared to some others out there. It does help our attorneys because, with attorneys, time is money. It helps alleviate downtime. I don't think that Citrix actually saves me any money, but it prevents me from losing any.

The most valuable feature has to be the non-persistent desktop. If one of my users messes something up and blows away their desktop, it goes back to what it was originally, before they had an issue.

Our employees also absolutely love the flexibility of using it on any device. We have quite a few people who use iPads and they really like the experience on that, regardless of where they are. The only difference is that the speed of the connection changes, but nothing else does. The consistency is huge.

The solution's centralized policy control and distributed enforcement work well. We have the desktops locked down so users can not add their own software. That's centrally controlled and it does make it easier to be able to present a consistent experience.

I also like that we have redundancy built in. The last time we upgraded, which was three years ago, we put in dual controllers and dual storefront machines. We have never had an outage that the users were aware of. I did have a desktop server crash and was able to restore that from backup. Nobody ever knew. They had had the same experience regardless.

The only thing we have found to be detrimental is when we have tried to find training. I realize that we're looking at it at the worst time possible, with a pandemic going on, but it seems that most of the training offered is learn-by-yourself online. I have a desktop admin who would love to be able to dig deeper into group policy and settings, to be able to admin Citrix a little bit more easily. That's the only thing that I would like to see an improvement on, the availability of training for novice users.

I've been using Citrix for at least 14 years, maybe 15.

It's very stable. It's one of the most stable software applications I run. You set it up and it just goes.

In terms of scalability, it seems that the only things that limit you are your number of licenses and your compute. So scaling is very easy.

Prior to the work-from-home initiative, I had about a dozen users who consistently used it. After COVID and the work-from-home, even though I had only 20 licenses, I had 24 people who were using it. Those four extra people were working part-time in the office and part-time from home so they shared the license. When one was in the office, the other would use it, so I never exceeded my license capacity. And now, since the State of Idaho lifted work-from-home, I'm back down to about eight people who are on it consistently.

The support is excellent. They are wonderful. Luckily I have only had to use them once for a critical issue. I got on the phone, was transferred to an engineer, and had it resolved in less than 20 minutes. For minor issues that are questions, they usually have those resolved in less than 24 hours. And usually, the delay is on my end getting their fix implemented and responding.

We had tried Microsoft Terminal Services and found it sadly lacking for the user experience. We went ahead and implemented Citrix and we have been using it ever since. Terminal Services was Microsoft's attempt to do a remote desktop presentation and it failed miserably. There were a lot of issues and items with Terminal Services. The biggest advantage with Citrix was the consistent experience. Terminal Services was not consistent. If you got too many users on it, desktop icons would move and applications wouldn't load.

While the centralized policy control and distributed enforcement work well, I wish we understood it better. I had a local engineer with Citrix certification build my farm for me. Since it was a brand new concept for me, it was very difficult to grasp at first. He did some preliminary training for us: How to admin it, how to update, how to make things run. But I am in no way an expert on the back-end. If I was able to take the time, which is kind of hard, to learn how all of the nuts and bolts work, I could improve the user experience a little bit. It's a lack of knowledge from my side.

From start to finish, our deployment took about two weeks, and that was mostly because the engineer could not dedicate his full time to me. It was a couple of hours here and there. Overall, the time billed was about 20 hours.

We built the servers, we tested the servers, and then we pushed them out to the handful of attorneys who had requested the ability to work from home. Then we fine-tuned it from there. I really let my users be my test-bed.

Any maintenance is done by me, but it requires minimal maintenance, mostly upgrades.

My advice is get an engineer. Their knowledge can't be matched. A very good one will do it as an educational experience, so you learn as you go. Having somebody who knows Citrix inside and out build it, with best practices and what would suit our needs the best, was invaluable to me. And our engineer has provided support on the minor things afterwards and that has been wonderful. I love the support.

My users either love it or hate it. There is no in-between. The ones who love it do so because it is very consistent in how it works. You log in, everything works. It's the same desktop, the same software, every single time. The people who hate it are the ones who use their desktop to store things, and I don't save the world on their desktops. As soon as they hit that 2 GB mark, I start deleting things. Those are the people who don't know how file stores work.

Even though we run the servers on-prem, we advertise it as a "cloud solution" since it's accessed through a web portal, and that has helped quite a bit in pushing my user base to understand what "cloud" really means. I can see moving this off-prem to a cloud solution in the future, but at this time my budget is frozen, so it's not going to be anytime soon.

I usually don't have to refer to the solution's behavior analytics for detecting anomalies because if something isn't working optimally, my users let me know immediately. They're very vocal if something isn't the way they expect it to be.

As a care provider we provide hospital and community health services with around 3,200 staff at the hospital and a further 650 community staff who work in local clinics and in patients' homes. On 1^st April 2020, we acquired our first primary care practice as part of our move towards being an integrated care system.

In terms of Citrix our biggest use case is for remote access and remote control. The former provides a VPN connection and the latter a published desktop. Prior to the onset of the COVID virus we had a 200 concurrent connection license covering both types of connection but today, following an NetScaler upgrade we now have a license for 1,000 concurrent users. Typically we're running 500 to 600 connections out to those locations every day.

Our hospital systems are a mix of SaaS and on-premises solutions. Our primary clinical platform is the Cerner Millennium electronic patient record (EPR) system, and that is delivered entirely over Citrix. However, we also use Citrix on-premises to deliver a range of services, including modern workspace, sharefile, load balancing (over 4 NetScaler’s) and of course remote control and remote access. Recently we have been working with Citrix to develop a thin-client workstation-on-wheels, for use on our hospital wards and believe this to be the first of its type. That's really where the relationship with Citrix has stepped up, because we're doing some new, innovative work.

We've consolidated all of our previous licenses into the latest version of the Citrix Workspace Premium Plus package to optimise the value received from the investment and are shortly to tender for a new support package that we expect will see us engage directly with Citrix.

The Citrix technologies allows us to do some clever things. For example, it has enabled our Radiologists review images that are quite large at home. Imagine trying to squeeze a 20Gb mammogram down a broadband connection, it is simply not practical. Yet by combining the Citrix technology with a specialist workstation from our Imaging partner, we're now able to have radiologists working successfully from home, reviewing MRIs, CTs, plain films, etc., because all we're sending are keystrokes and screen updates.

In terms of Security. Our organization has achieved the Cyber Essentials Plus security accreditation. My organization takes security very seriously. In fact, as far as I know, we're the only hospital in our region that has three full-time staff who work on security within the IT department. We very much take that Zero Trust position and ensure that we provide the necessary policies and controls to protect our organization, but not to the point where we impact our agility or flexibility in terms of supporting people who genuinely have a need.

We've built a strategic relationship with Citrix and we use a lot of their products for everything that we do. I would rate the Citrix stack highly as an end-to-end solution for implementing Zero Trust principles. It's allowed us to do a lot of things quickly and flexibly, and some of the functionality that has become available as we've moved into the newer, more advanced versions of the Citrix software, have proved very beneficial.

Among the most valuable features is the Citrix Workspace, which allows us to drive that thin-client connection and the remote control/remote access capabilities. Those things have allowed us to connect an awful lot of people quickly from home and that's obviously helped during the pandemic. There's a concern right now that a second wave of the Corona pandemic is on its way so we're gearing up now to enable a second wave of staff work either from home or from an alternate location. This way we can reduce the number of non-clinical staff in the hospital whilst not degrading the services we provide in any way. Fundamentally we are seeking to keep the number of staff working at the hospital down to only those who actually need to be there.

The user experience, when using Citrix technology remotely, is very good. It's easy to use and I say that with some authority because I've been working from home now for about six months. I've been able to do my role as the CIO entirely from home. I log on through the Citrix gateway first thing in the morning when I start the day and I stay logged in until 5:30 or 6:00 o'clock at night. I've been able to gain access pretty much whenever I want and it's just two clicks to get me there.

I've got friends who work on the wards who use the Citrix client on our workstations-on-wheels and they find it relatively easy. They load the Citrix client, they click on the link to the EPR, and that's it, off they go. Because it's a thin client, because we're not dragging huge amounts of stuff over the network, they get very good performance out of their equipment. And that's allowed us to extend the life of some of our very early workstations-on-wheels. Some of them are now four years old and are coming up for replacement. Indeed that's what we've been doing with Citrix, building the next generation of workstations-on-wheels, to benefit from what we've learned by working with Citrix and partners to deploy this new technology.

The prototype is built and is currently being tested. When we go live we'll see a big step forward in terms of the performance, a notable increase in battery life and the corresponding reduction in the number of times the unit has to be recharged.Those are things that our nurses have told us will be of benefit to them.

The solution also provides the flexibility of being used on any device. We have a mixture of Windows PCs, Android mobile devices, Apple tablets and other Apple devices. We have Citrix installed on all of those and it allows our users to use these devices for any number of things. They can use it for clinical access, bringing patient data quickly to the clinician. For example one such system is the EDM (electronic document management) system that holds the scans of all of our paper documents and using Citrix staff can switch between the EPR and EDM and so get a complete picture of the patient's health. On a more basic note it can also be used to access tasks lists, calendars and email – helping to manage busy lives at a time when hospital staff are working under extreme pressure.

It affects the employee experience in a very positive way because of the way in which we have combined the remote connectivity with the Citrix tools. That means that as long as you have the right level of authorization, you can access a great deal of information from anywhere, and you can do it in one of two ways. If you have a hospital device that belongs to the Trust, then you've got a very high level of access to a lot of information because we can then employ end-to-end security. But if you're at home and you're using your home computer, you can still connect. It's just that there is no data transfer and the performance is less through the published desktop than it would be through the remote connection. But both situations work really well and, obviously, have been tested very severely with the Coronavirus where, very quickly, we had to give a lot of people the ability to work from home. One of the ways we did that was to allow them to use their own computers and come in through the Citrix desktop connection.

It takes a little bit of work upfront to get it configured and operable, but given the length of time we've been working with Citrix and the strength of our relationship, we're normally able to get any glitches ironed out and resolved quickly. That allows us to provide both a strong suite of applications to our users and a good user experience.

In terms of automated analytics to detect serious performance issues, what happens is that Citrix work with us and provide a monthly health check. This service monthly provides a series of analytics reports and tell us that it's all working, or if there is any issue they work with us to get it resolved.

Where improvement could be driven is in terms of clarity as to the functionality of some of the solutions. If you go back to the older Citrix Xen products that we had, we understood those really well. As we've come into the new workstation premium suite, there is a lot of additional functionality that we perhaps have not yet fully exploited. It is not because we can't, but simply because we don't yet understand the depth of functionality that's offered.

We made the upgrade to the Workspace suite last year we had planned to train this year but then the pandemic struck. We've only had one thing on our minds since March and that's how do we keep the hospital running? How do we make sure we keep people safe? And how do we treat patients in the face of a once-in-a-century experience?

Citrix have offered to help with demos or presentations of these new features, but we also simply haven't had time to dive in.

I joined the Trust on the third of January, 2017. At that point the Trust was already engaged with Citrix, so it's at least five years or more.

The solution is absolutely rock-solid. I'm almost scared to say this, but throughout the whole stress of what we've been through over the last six or seven months due to COVID, Citrix hasn't missed a beat. It's been solid and reliable. We've had no downtime. It's been absolutely on the money, and given how critical it has been to get people connected and working, the 100 percent reliability has made me very happy.

We're happy with the scalability. We were able to increase a 200-user solution to a 1,000-user solution simply by buying an upgrade to the license. We chose to buy two additional NetScalers, bringing our total to four, but that was largely because we bought the initial upgrade from 200 to 1,000 to allow us to connect the 640 staff who work in the community. But then, the hospital's need for remote access and remote control overtook that. That's what drove us then to buy a second set of NetScalers because we didn't really want to put some 4,000 users through just one gateway (pair). We felt having two gateways would be safer from a resilience point of view. And having two NetScalers per gateways means that we can take one down to do maintenance updates without disrupting the service.

In the next couple of months, we'll start to plan what next year's digital program looks like. The way in which we operate is that through November, December and January we engage with operational and clinical colleagues to determine how we are going to exploit IT to enable transformation going forward. We then build a digital program for our Digital Board to sign off on. As we go through that exercise, looking at how we can deliver better healthcare for our patients and improve the clinical experience, we will be looking to Citrix to help us understand how we can better exploit the new software that we've invested in. Normally by now, having bought it last year, we would have been well into it, but the pandemic has somewhat focused our minds elsewhere.

Given that we are building these new, next-generation workstations for use in the clinical areas, it's been great to see just how much support and help we've had from our partners including Citrix. They've recognized that it is something new, that it is something that will help hospitals (not just ours) to deliver services that are more reliable and quicker in busy clinic areas and on wards. It's been a huge pleasure to work with some of their very senior people on a project of this scale.

You often find when you're working with tech organizations, and you step it up to do something that's not straight out of the sales catalog, that some step up well and some don't. Citrix have really stepped up well. They've kept in close contact with us, they've supported the design and they've helped us to consider options at the build level. We're delighted with that. We've built a prototype that's being tested at the moment and we look forward to that going into production. We'll probably hold some sort of press event to talk about what we've done. It's the strength of the partnership that we enjoy with Citrix has allowed us to do that.

The very initial setup was done before I arrived at the Trust, but I have been involved in all the major iterations that we've gone through since. Some of them were relatively easy to do, others were more complex. Getting the license upgrade to increase the number of remote access sessions and upping the size and capability of the gateway was relatively easy. It took a few phone calls, purchasing of the license, and off you go. But configuring the VPN and the Citrix published desktop so that they work within the security model that we have did take more work than we had originally expected.

In some aspects, when you bring software products together from three different vendors, there is always a little work to do to get APIs aligned and to get the solutions talking to each other so that the user then gets a very slick experience. We do such things all the time with our IT department usually spending the most time on testing, especially when the solution is for use with patients. We seek to ensure that when we hand something to a busy doctor, a senior nurse or a therapist that they don't need to have an enormous amount of tech knowledge to be able to use it. They just click on the buttons, enter the information and press go, and it does what it needs to do.

In terms of how long these updates take, the remote access and remote control was a solution that was built for 200 concurrent users. Today, it's built for 1,000 concurrent users. It probably took about two weeks to agree on exactly what software license we needed to buy, about a week to procure it, and about three hours to embed it. That was quick and easy to do. 

In terms of the Citrix desktop, we couple that with a second form of authentication that comes from a third-party, and that took six to seven weeks. It didn't take that long to get it to work—we got it to work quite quickly—but it took that long to get it to work smoothly. It took time to work with the three different application vendors that were involved and iron out the bugs and make it work as we wanted. But most of it, particularly where it's just us dealing directly with Citrix, happens quickly and easily.

If you think about our ability to continue to operate as a healthcare organization during the pandemic, without Citrix we would have struggled. We would have found it very difficult to have so many people able to continue doing their day jobs from locations other than their normal bases. It is therefore fair to say that the ROI on our connectivity investment was excellent. Yet this does not stand in isolation as the delivery of our electronic patient record system using clinical workstations-on-wheels is all built over Citrix technology. Absolutely, for every pound we've spent, we've seen a good ROI.

I'm happy with the pricing. The cost of the Citrix software reflects what I would expect a product of that nature, in that market, to be.

Understanding the licensing is quite a bit more complicated, because one of the things about Citrix is that you can buy licensing at different levels. You can buy a basic license, which will give you the core functionality. You can buy an advanced license that will give you the core plus another layer, or you can buy a premium license, which provides a much wider set of functionalities. In truth I still struggle with some of the variations but with the aid of our reseller we usually find what we are looking for. Yet I still like the idea because it means that if all you need is a basic load balancing solution, then you don't need to buy an advanced or premium license. On the other hand, if you want to use the extra features that come with those higher-grade licenses, you can choose to do so, but you only pay for what you need.

The only comparable I can think of is that we use software from a different party for virtualizing servers. But we were aware that in terms of the ICA-type protocol, Citrix was the product that everyone was saying was the best. Indeed, I've worked with Citrix for a very long time - I guess a little over 20 years, so I never had really had any intentions of looking anywhere else because I believe that it's the right tool, to do what we need. In truth I have not seen any compelling evidence to make me think otherwise.

My advice is to spend more time planning than you do implementing. Get what you need—the components that make up the solution—all agreed and lined up before you then commence the build work. I know that's really easy for someone like me to say, when you're under pressure and your organization needs something built very quickly. Therefore, to make sure that you generate the most benefit from your investment and you drive the features that really help, spending a little more time in the planning phase and making sure that you've got the right type of license, the right application or appliance required to do the job as this will save a lot of rebuild work or remodelling work down the line. It will also mean that if you want to grow it for scaling purposes, it will be far easier to do if you've thought about that before you implement the solution.

One of the lessons I have learned from using this solution is the fact that we have been able to be agile and respond to the needs of the organization through the use of the product. That has been a very good side of things. Another side of the lessons learned is that when we paid for the upgrade to move to the premium suite, we could have engaged earlier with Citrix to understand the additional functionality. We knew ahead of time that there was additional functionality, but in terms of the detail, we didn't get into that and then we got overtaken by the pandemic. In a normal year that wouldn't have mattered, but the lesson I've learned is that if we take an upgrade in the future, if we take the next step forward to a next generation of that software, I want to try to ensure that the purchase and the training of my engineers are closely coupled.

As for protecting our environment, we use Citrix Gateway, but the single sign-on is provided by another partner of ours. We have Tap and Go, Remote PC Access, Web App Gateway. We do have Web/URL filtering, but not from Citrix.

In terms of maintaining the solution, I have resources at both 2^nd and 3^rd line engineering that have Citrix skills and who look after the day-to-day stuff. In addition we have a contract through a Citrix partner and so can escalate calls that we can't handle. We spent time and effort putting our engineers through Citrix training. But occasionally, something comes up and we're not able to resolve it. At that point, we log a call via the partner and the partner's engineers, and Citrix's own engineers, get involved. Normally that results in a relatively quick resolution. The Citrix engineers clearly know the product really well. They'll quite often say, "Oh, we've seen this before. You need to do this or that or the other." As I said, we've had very few issues with reliability on the Citrix platform so those calls are actually quite rare.

Overall, I love it. It's been a really good product. It's helped my organization and helped me to deliver what the organization wants. For me, Citrix takes 10 out of 10.

For example, right now I'm at home, and my connection to the hospital runs over the Citrix VPN that we've created. We also have Citrix Remote PC Access, so if you are home and you're on your own computer, rather than one that belongs to the hospital, you can access the published desktop rather than having full VPN access.

We're a fairly big Citrix customer. We're doing some quite ground breaking stuff with them. We're beyond just being a customer. Traditionally, Citrix is positioned in the marketplace as a manufacturer. They sell through channels and the customer deals primarily with the partner. Because of the amount of work we've done, we primarily deal directly with Citrix themselves. There is a partner involved because that's the only way of doing the sales component of it, so if we want to buy something that has to be through the channel. But the work that we're doing is being done alongside engineers who are employed by Citrix rather than by the partner.

For virtual desktops, like Windows 10 or Windows 7, we primarily use the solution to offer some customized applications to the users. 

Some of the basic applications, like Windows applications, are being used across all VDIs. 

The usage depends on the specific customer. They decide what applications they want to have in their VDI. We have certain items as far as their requirements, and we just manage the infrastructure in the background.

Citrix tends to have the most capabilities surrounding desktops.

The application virtualization is very, very good.

The customer is always looking for a unified solution. They need a single place where everything can be managed from while using a web application. With Citrix's system, there's an administrative tool and a helpdesk tool. Those two tools are very different, and the Citrix administrative tool is not meant for web-based use. It's in a heavy application. If they could build it into their web-based applications, that would be ideal. That way, administrators can log in from anywhere on any browser and they can just manage the environment in the background. 

Citrix does not have an in depth assessment tool. Some customers ask for components in Citrix that can give information around the hypervisor's resources or in-depth metrics of the hypervisor's site. There is a free tool from Citrix, however, it does not give you the deeper information of the other components like hypervisor or the OS or the storage, or downloads in the network. Those are the limitations of that particular tool right now. We might need to use a third party tool to gain that information. 

If Citrix can develop something which can have more reach towards the backend infrastructure, other components of the Citrix environment, that would be ideal. 

We've most likely been using the solution for over eight years at this point.

Citrix is one of the companies that is delivering virtual apps and desktops in a big way. They are mature enough to understand the level of stability required and deliver it. 

Now, they are moving towards the cloud and offering everything as a service. The redundancy part is already taken care of by the company. 

We have many components and have controlled redundancies. From the end-user side, a user won't see any disruption in the services. That's due to the fact that the infrastructure in the background is highly available. Elasticity is also introduced. We're always building provisioning desktops on-demand and shutting the machines that are not in demand. 

We have certain policies defined in the infrastructure in the background, which can enable our administrators to utilize the resources as they need them. Therefore, it's quite stable.

We use this solution ourselves in our own organization and have a 60,000-70,000 userbase currently. We have more than 40 customers within the virtual workspace. Most are medium-sized entities. A few have 20,000-40,000 users. We'll be adding another client in healthcare that has about 20,000 desktops.

Scalability is not an issue. You can scale up to any number. There's only the requirement of adding the infrastructure and building that horizontally. You'll need to set up the different components horizontally. For example, if we have a 10,000 user base, then we can probably have 10 master servers. If the user base is around 40,000, then we can double the master servers so that they can take up the load.

We often contact technical support.

They are very engaged, whenever we have an issue. They are very helpful. Most of the time, whenever we run into an issue where we need to reach out to Citrix they are available to us.

We do not support only Citrix. We also support the backend infrastructure and hosting infrastructure that are also Citrix products. If it's tied to another product, such as Microsoft, they'll work together to resolve whatever the issue is. 

We haven't found any difficulty in working with them. It's rare that we'd need to reach out to other vendors as well as Citrix (usually once in a quarter), however, if it happens, we know Citrix will do what they can to work with all parties.

We do not exclusively work with Citrix. It's much more high-end than other services, however, we do also offer, for example, VMware and Horizon.

The initial setup is very simple currently. Earlier we used to install many components separately. Now, we have a basic software installation setup. We can build the environment in a few hours. It does not take much time now. Earlier, we used to have to secure the servers, for example. It is all virtualized. One administrator can build the environment from scratch and in a very short period of time. It's not complex now. Earlier it was, but not anymore.

The deployment time depends on the sizing of the environment. If the customer is looking for only 500 desktops, it takes one day to build everything. If there is planning involved, and there are some different components or key bits and pieces that the administrator needs to collect, it might take a bit longer.

If it is in a scalable environment that's sized, for example, at 1,000, 10,000, or 20,000, it will definitely take time. This is due to the fact that we need to choose the appropriate technology for the background. We need to figure out if the customer's willing to have a provision desktop, basically. That all depends on what the customer size is and what the customer requirements are.

We also offer managed services, so we can help our clients manage everything once the solution is fully deployed.

Our team can help implement the solution for our clients. That said, I don't handle the process directly myself.

Citrix is competitive, however, at the same time, they give great service. VMware, Horizon, or other VDI solutions may be cheaper. That said, they do not have the same capability that Citrix has. 

We offer other VDI solutions like Microsoft WVDs and the VMware's Horizon, that are on the cheaper side. It's up to the customer, what they want to do. If they want to have premium services, we will host their VDIs on Citrix system components only. That will give them better features and better capabilities or maybe less frustration on the user experience side.

We offer cloud and managed services offerings as well as environments hosted on our data center. We have a variety of options and therefore can offer a variety of prices according to what they need/want.

We're currently using the latest version of the solution.

While we mostly work with on-premises deployments, we also occasionally handle cloud deployments as well. 

We have our internal Cloud offering. Form there, we have a managed data center and within our company's premises, the customers are just subscribing to services based on their need for virtual desktops.

I would recommend the product. It's an industry leader in the VDI environment. Nobody can match their capabilities right now.

I'd rate the solution nine out of ten overall. If they had better capability testing, I might rate it higher.

My focus has primarily been on publishing virtual applications.

Pricing and technical support need improvement. 

I have been using Citrix DaaS (formerly Citrix Virtual Apps and Desktops service) for fifteen years. 

The scalability of Citrix matches with almost all devices. 

The technical support was challenging in the beginning but now it seems to improve. 

The initial setup is straightforward. 

Overall, I rate the solution an eight out of ten. 

Citrix Virtual Apps and Desktops is used to control our virtual machines and provide access to our devices from anywhere.

Citrix Virtual Apps and Desktops is capable of deploying and managing all servers or virtual desktop infrastructures.

The cost of Citrix Virtual Apps and Desktops is high and has room for improvement.

The technical support is slow and has room for improvement.

I am currently using Citrix Virtual Apps and Desktops.

Citrix Virtual Apps and Desktops is a stable solution.

Citrix Virtual Apps and Desktops is a scalable solution.

The quality of technical support is very poor. Insufficient staffing has resulted in delays in responding to tickets.

The initial setup is straightforward. The deployment process is simple. We just need to deploy the VDI server and its VDA.

The implementation is completed in-house.

Citrix licensing is expensive.

If we deploy in Azure, Microsoft has an advantage over Citrix because it provides effective solutions for deployment and management.

I give Citrix Virtual Apps and Desktops a ten out of ten.

Citrix Virtual Apps and Desktops is recommended for midsize and enterprise companies because it is not affordable for smaller organizations.

I recommend conducting an analysis of the organization's requirements and compiling a list of viable solutions before proceeding to a proof of concept.
