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."Amazon Elastic Load Balancing transfers the data securely from servers to users and splits the traffic based on peak times."
"Security and monitoring for high-performance applications are some of the top features."
"The most valuable feature of Amazon Elastic Load Balancing is scaling."
"The solution is very well integrated into Amazon's services."
"It has very good features. It is very configurable. Security with TLS, et cetera is also very easy."
"It is straightforward to deploy."
"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."
"The solution offers good load balancing."
"The maintenance of the solution is not complex."
"The solution is extremely stable."
"The most valuable features of Citrix ADC are load balancing and application firewall."
"Content Redirection and SSO integration with Citrix XenApp/XenDesktop. The GUI was wonderful."
"The GSLB feature allows us to move services between data centers. We can do this in either a planned or unplanned manner. We have experienced service provider outages at our primary data center and GSLB will kick in to automatically modify DNS records to point to a secondary data center (active/passive). We also make use of GeoIP information to point clients to the closest data center for accessing applications."
"HTTP analysis and action. We have a lot of custom web applications that sometimes require custom header insertions. Some of these custom apps are external and, via the content switching, we can use one IP and leverage various back-end web app servers."
"The load balancing feature and the fact that you can do context switching in the WAF are the most valuable. We majorly use it for load balancing, but we also use it for context switching in the WAF. It is also robust and very easy to work with and manage."
"The web application firewalling component is a powerful feature."
"The solution needs to guarantee stability because multiple loads behind a load balancer can cause service unavailability."
"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."
"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."
"They should improve the solution's pricing."
"The product's stability is an area with a slight shortcoming, which can be improved."
"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."
"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."
"Technical support could be improved."
"The GUI should be improved."
"We would like to see some fairly large scale improvement in the configuration process for this solution."
"The technical support could be better. Whenever I contacted support, I rarely got the solution that we needed. And most of the time, I finished fixing the problem by looking on the internet or by finding documents about the problem on Google."
"Citrix should improve the documentation. It is not really clear how to set up many features to our advantage. When we setup Citrix NetScaler ADC, we have to figure it out by ourselves without a lot of documentation."
"It can be difficult to setup."
"In every release - and it doesn't matter if it's a minor release or a major release - they keep moving things around and they keep changing the mechanism. So certain things can work in one version one way, and everything works really well, then when you upgrade it to the next version, it breaks everything because they have a new way of doing it."
"Technical support sometimes takes a little longer because of the multilevel ticket priority."
