Saves time during workload migration, facilitates sizing of virtual servers, and the support team is helpful

The right-sizing feature is the most captivating one for us. It helped in taking the emotions out of what people think they need, basing it off of real data, and providing them what they actually need. It's not really a special feature, but the support that we received from that team really helped us in our success. There were definitely some customizations that needed to take place to make it successful. This is the most aware of our products, in terms of understanding all of the components from the top down. It is integrated with all of the different modules, all the way down to the core infrastructure. All of it is tied together and there are not many tools that can do that.

Products Manager at a tech services company with 501-1,000 employees

Reliable, simple to manage, and offers great technical support

The support of VXLAN fits with our network management. Thanks to this we can propose mixed solutions using virtual resources on OpenNebula and bare metal servers hosted in our facilities linked to each other on the sale network. This use case is very useful when some applications need bare metal power (Kubernetes workers, huge databases, AI models computations, et cetera). The cluster management is very useful for splitting our different clusters (mutual vs dedicated). We can manage deployments and capacity planning without pain. The API is also really simple and it helped us to develop the Terraform provider to manage OpenNebula like any other cloud infrastructure.

Provides crystal clear dashboarding and allows you to manage and monitor your infrastructure

The overall dashboarding is very crystal clear. The ability to switch from one infrastructure to another infrastructure and get into detailed information, whether it is compute, storage network, or whatever. That helps you get a holistic view of the overall infrastructure running in your landscape. This also helps the leadership and management be aware of the right potential investment strategy by looking at the potential utilization. vCloud Director also provides ways and means through which you can make a prediction or a forecast of the infrastructure that would be needed in the future, depending on what you are currently running. That does not take away the fact that we have to be completely aware of our pipeline projects in our schedule so that you can plan your infrastructure requirements accordingly. vCloud Director provides multifold features that have been beneficial to the end users.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros

"The recommendation of the family types is a huge help because it has saved us a lot of money. We use it primarily for that. Another thing that Turbonomic provides us with is a single platform that manages the full application stack and that's something I really like."

"With over 2500 ESX VMs, including 1500+ XenDesktop VDI desktops, hosted over two datacentres and 80+ vSphere hosts, firefighting has become something of the past."

"The tool provides the ability to look at the consumption utilization over a period of time and determine if we need to change that resource allocation based on the actual workload consumption, as opposed to how IT has configured it. Therefore, we have come to realize that a lot of our workloads are overprovisioned, and we are spending more money in the public cloud than we need to."

"It also brings up a list of machines and if something is under-provisioned and needs more compute power it will tell you, 'This server needs more compute power, and we suggest you raise it up to this level.' It will even automatically do it for you. In Azure, you don't have to actually go into the cloud provider to resize. You can just say, 'Apply these resizes,' and Turbonomic uses some back-end APIs to make the changes for you."

"The primary features we have focused on are reporting and optimization."

"I have the ability to automate things similar to the Orchestrator stuff. I do have the ability to have it do some balancing, and if it sees some different performance metrics that I've set not being met, it'll actually move some of my virtual machines from, let's say, one host to another. It is sort of an automation tool that helps me. Basically, I specify the metric, and if I get a certain host or something being over-utilized, it'll automatically move the virtual machines around for me. It basically has to snap into my vCenter and then it can make adjustments and move my virtual machines around. It also has some very nice reporting tools built around virtual machines. It tells you how much storage, memory, or CPU is being used monthly, and then it gives you a very nice way to be able to send out billing structure to your end users who use servers within your environment."

"We have seen a 30% performance improvement overall."

"Turbonomic can show us if we're not using some of our storage volumes efficiently in AWS. For example, if we've over-provisioned one of our virtual machines to have dedicated IOPs that it doesn't need, Turbonomic will detect that and tell us."

More IBM Turbonomic pros

"The solution provides templates for configurations that can easily be exchanged to VMs."

"It's easy to integrate OpenNebula with our IT systems."

"For the entire data center, as a private cloud, I believe that user management, expert management, and the virtual data center is completely magic for the users."

"The live migration feature has been great and is something we use very often."

"The service feature appeals most to us, thus it is the most valuable."

"The most valuable feature of OpenNebula is that it scales very well."

"OpenNebula has very good integration with SAP Storage."

"OpenNebula is easy to deploy and manage compared to other solutions like OpenStack."

More OpenNebula pros

"They can do any provisioning for the virtual machines. For instance, they will only see those resources if we allocate 10 Ghz database storage. The limitation is due to our setup: we need to ensure customer isolation, as vCloud Director supports multi-tenancy."

"There are various options for scaling and that flexibility is a good option."

"VMware Cloud Director is quite scalable; I would rate it nine out of ten."

"The reliability and flexibility of networking are valuable."

"The overall dashboarding is very crystal clear."

"The self-service portal is the most valuable. We are acting as a service provider, so our customers can take care of their virtual data centers with the self-service portal. Therefore, we don't need staff for it."

"It helps ensure security across our cloud environments."

"The product allows us to add or remove features."

More VMware Cloud Director pros

Cons

"Additional interfaces would be helpful."

"There is an opportunity for improvement with some of Turbonomic's permissions internally for role-based access control. We would like the ability to come up with some customized permissions or scope permissions a bit differently than the product provides."

"It would be nice for them to have a way to do something with physical machines, but I know that is not their strength Thankfully, the majority of our environment is virtual, but it would be nice to see this type of technology across some other platforms. It would be nice to have capacity planning across physical machines."

"If they would educate their customers to understand the latest updates, that would help customers... Also, there are a lot of features that are not available in Turbonomic. For example, PaaS component optimization and automation are still in the development phase."

"It sometimes does get false positives. Sometimes, it'll move something when it really wasn't a performance metric. I've seen it do that, but it's pretty much an automated tool for performance. We've only got about 500 virtual machines, so lots of times, I'm able to manage it physically, but it's definitely a nice tool for a larger enterprise that might be managing 2,000 or 3,000 virtual machines."

"The one point is the reporting. We do have reports out of it, but they're not the level of graphical detail I would like."

"I like the detail I get in the old user interface and will miss some of that in the new interface when we perform our planned upgrade soon."

"The issue for us with the automation is we are considering starting to do the hot adds, but there are some problems with Windows Server 2019 and hot adds. It is a little buggy. So, if we turn that on with a cluster that has a lot of Windows 2019 Servers, then we would see a blue screen along with a lot of applications as well. Depending on what you are adding, cores or memory, it doesn't necessarily even take advantage of that at that moment. A reboot may be required, and we can't do that until later. So, that decreases the benefit of the real-time. For us, there is a lot of risk with real-time."

More IBM Turbonomic cons

"As with all enterprise software licensing, the pricing is not intuitive and must be negotiated; grandfathered contracts are better than anything offered today."

"The protocol for clusterization is rough and doesn't work well."

"There are small things that are hard. For example, making sure that it is going to be installable on public clouds."

"The UI, monitoring, and alerting could benefit from further improvements."

"There are no payment gateways in OpenNebula."

"They have been saying for the past two and a half years that they would develop a feature to hot-add RAM and CPU, but it does not work."

"The web interface could be better. It's not very difficult to use, but there's room for enhancement."

"They should add more features like object storage."

More OpenNebula cons

"What could be improved in vCloud Director, particularly from the networking side, is its integration with other network devices. It also needs a more simplified installation because the process is a little bit complicated."

"I would like to see mode accessory recovery and integration with SD-WAN."

"We are having a bit of a problem with vCloud Availability. We know that vRA has a new product, HCX. We would like to know about it, then migrate to the product."

"The initial setup is not straightforward; it can be complicated. The deployment can take one to two weeks."

"There are too many errors, it could be more stable."

"vCloud Director should improve by having support with other cloud providers, such as Microsoft Azure and Google cloud."

"If I just need to look for something quickly, it's quite difficult to find it with the way it's set up now. They should make the search button better."

"In version 6.7, compatibility to migrate VMs from a vCenter to vCloud Director had a problem. However, this has been solved in the newest version."

More VMware Cloud Director cons

Pricing and Cost Advice

"The pricing is in line with the other solutions that we have. It's not a bargain software, nor is it overly expensive."

"Licensing is per socket, so load up on the cores rather than a lot of lower core CPUs."

"I'm not involved in any of the billing, but my understanding is that is fairly expensive."

"Price is a big one. VMTurbo was very competitively priced."

"I don't know the current prices, but I like how the licensing is based on the number of instances instead of sockets, clusters, or cores. We have some VMs that are so heavy I can only fit four on one server. It's not cost-effective if we have to pay more for those. When I move around a VM SQL box with 30 cores and a half-terabyte of RAM, I'm not paying for an entire socket and cores where people assume you have at least 10 or 20 VMs on that socket for that pricing."

"If you're a super-small business, it may be a little bit pricey for you... But in large, enterprise companies where money is, maybe, less of an issue, Turbonomic is not that expensive. I can't imagine why any big company would not buy it, for what it does."

"I know there have been some issues with the billing, when the numbers were first proposed, as to how much we would save. There was a huge miscommunication on our part. Turbonomic was led to believe that we could optimize our AWS footprint, because we didn't know we couldn't. So, we were promised savings of $750,000. Then, when we came to implement Turbonomic, the developers in AWS said, "Absolutely not. You're not putting that in our environment. We can't scale down anything because they coded it." Our AWS environment is a legacy environment. It has all these old applications, where all the developers who have made it are no longer with the company. Those applications generate a ton of money for us. So, if one breaks, we are really in trouble and they didn't want to have to deal with an environment that was changing and couldn't be supported. That number went from $750,000 to about $450,000. However, that wasn't Turbonomic's fault."

"I have not seen Turbonomic's new pricing since IBM purchased it. When we were looking at it in my previous company before IBM's purchase, it was compatible with other tools."

More IBM Turbonomic pricing and cost advice

"OpenNebuoa has recently come up with a new subscription model that is economical and a lot of new customers are choosing this as it is an easy subscription model."

"The solution is open source so is free."

"VRA is very expensive but OpenNebula is free."

"The licensing for OpenNebula used to be free, but now it's no longer free. A customer contacted me asking to move to another provider because of the changes in the licensing terms for OpenNebula. I have no information on how much the OpenNebula license is because the customer pays for it, and I only do the integration."

"We use the Community Edition, rather than the Enterprise Edition."

"OpenNebula gives good value for money."

"We are paying around $ 15,000 per month for vCloud Director, and it would be nice if it could be made cheaper."

"It is better than other solutions out there when it comes to cost."

"It's a costly product. The licenses may not be costly, but with every new development in their product, we need to purchase deployment services, and the deployment services are quite costly."

"The solution is costly, efficient, and robust versus alternative solutions."

"On a scale from one to ten, where one is cheap and ten is expensive, I rate the solution's pricing eight and a half to nine out of ten."

"My company has no problems with the pricing of the product as we got good discounts from VMware."

"It enables us to provision new clients more quickly."

"vCloud Director is priced higher than other solutions, such as Nutanix."
