We performed a comparison between Amazon Elastic Load Balancing and Citrix NetScaler based on real PeerSpot user reviews.
Find out in this report how the two Application Delivery Controllers (ADC) solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Security and monitoring for high-performance applications are some of the top features."
"The solution is very well integrated into Amazon's services."
"It is a very scalable solution in which you can add more servers instantly."
"It is straightforward to deploy."
"Amazon Elastic Load Balancing transfers the data securely from servers to users and splits the traffic based on peak times."
"The feature that I like the most is the scalability. The solutions I build often have many pieces, which are very complicated. If a client comes to me with a design, my developer has made this as a template or a cloud formation script. It's a design on paper, and I want it executed a certain way. I can do that quickly and repeatedly with AWS. That is a considerable advantage because I can take that template and do it five times in different zones. That is an excellent feature based on a template, et cetera."
"It has very good features. It is very configurable. Security with TLS, et cetera is also very easy."
"The most valuable feature of Amazon Elastic Load Balancing is scaling."
"This solution allows the user to easily scale out application delivery, and provides secure remote access."
"Citrix Director has been great. It gives us one pane of glass to be able to monitor what's going on with the user sessions as well as to keep on top of the virtual desktops, any servers that may be offline or behaving suspiciously, or any troublesome spots like disconnections. We also use Citrix Studio for maintaining the actual servers that are hosting these applications. We use it for delivery groups in case we need to modify delivery groups in regards to which groups have access to which applications. It has been very helpful."
"The NetScaler appliance has provided a lot of customers with greater high availability for their enterprise applications within a single site and across multiple locations."
"The most valuable features of Citrix ADC are load balancing and application firewall."
"This solution increases the backend network service performance, which is one of the things that we like the most."
"For NetScaler, our major use cases are database load balancing, PowerVPN VPN access gateway, WAF (Web Application Firewall), and content switching."
"What I like most about Citrix NetScaler is its stability, and I didn't see a lot of issues with it."
"The flexibility in configuration options is impressive."
"One issue that we faced with ALB was that leaf-level certificate validation was not happening. It is not that user-friendly in that aspect."
"The product's stability is an area with a slight shortcoming, which can be improved."
"They should improve the solution's pricing."
"The solution needs to guarantee stability because multiple loads behind a load balancer can cause service unavailability."
"The reporting could be simplified so that the client sees a report of what they cached at the end of the month and the number of hits. It should have metrics above and beyond their Google analytics, etc. You can't do that with the solutions from AWS. You have to build sophisticated cloud trails, reports, dashboards, etc. The setup is significant, and it's hard to manage. You'll need to hire someone or pay a consultant on a regular basis to manage it, and it's not for the faint of heart."
"The machines created by Amazon Elastic Load Balancing have different IP addresses, which we are not able to whitelist or predict."
"We faced some issues with the health check."
"It would be good if we had a product that integrates well with third-party vendors. Some of our customers want a multi-cloud solution. They don't want to be tied up to or be in just one cloud."
"I feel that Citrix NetScaler's customer support needs to improve."
"We had some bugs in the previous firmware. These were not big issues, but more testing on the firmware would be key to happier customers."
"The technical support has room for improvement."
"Citrix ADC is a complex product, and it takes time to understand these things. But the documentation is poor, and the deployment is difficult. Integration could also be better because what I find is that you cannot easily integrate the panel in the second sector. What I have found is that in the last index, there is a limitation when getting validated. Technical support could also be better."
"I would like to see them make it easier to do some of the more complex things. For example, a web re-direct requires two pieces to it. You have two ports and when people want to go to a web page, they just type in the webpage that on the backend it will redirect them to a secure link. The initial setup of that is cumbersome because you have to do it twice. There are things that can be replicated. The IP address, for example, is the same. This change would go a long way. Don't make me do it twice and don't make me have to read tons of documentation to figure out how to do it. Ease of configuration for some of the more complex processes would be a good improvement."
"The solution could be more secure."
"I will try to migrate all the tools to the cloud because there is more lab and more VPN scalability available in the cloud. It is not available on-premises."
"The customization has always been a key area where some improvements are required. In the beginning, everything was for customizing the outer shell of it. You had to use the command-based utility and you had to do a lot of manual work. They have improved it a little bit and now there are some GUI-based functionalities that can be used. However, more can be done that doesn't require a lot of intervention. Right now there are some features, there are some customizations that can be done, but it's still very tedious, very cumbersome, a lot of work. So that could be simplified."
