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."The most valuable feature of Amazon Elastic Load Balancing is scaling."
"Amazon Elastic Load Balancing transfers the data securely from servers to users and splits the traffic based on peak times."
"The solution is very well integrated into Amazon's services."
"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."
"It has very good features. It is very configurable. Security with TLS, et cetera is also very easy."
"The solution offers good load balancing."
"It is a very scalable solution in which you can add more servers instantly."
"Most of the functions are user-friendly and great."
"It is a complete solution for those looking for an all-in-one."
"Citrix Netscaler makes it easy to provide services to end users, offering better visibility into user sessions compared to VMware. However, instability in network or machine can cause headaches as it's hard to pinpoint issues. SSL offload feature enhances security posture by providing secure connectivity between end users and backend systems. We use additional Azure remote security solutions for comprehensive protection."
"I like app flows and custom flows. They integrate with multiple flows."
"For desktop application management, I recommend the NetScaler edition. This product is like a Swiss army knife. Citrix NetScaler ADC supports the education front-end."
"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."
"The most valuable feature of Citrix NetScaler was the seamless integration. Additionally, the UI is good."
"The solution is easy to work with and manage."
"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."
"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."
"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."
"They should improve the solution's pricing."
"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."
"Improvements are needed to address the issue of machines becoming unregistered, ensuring stability for end users. Troubleshooting with Citrix support can be challenging, so clearer diagnostics would be beneficial. As for global server load balancing, it works well on-premises, depending on user volume and service stability. Overall, it's satisfactory for us."
"Maybe creating policies with simple regular expressions."
"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."
"The main areas for improvement would be around documentation and support. If a feature can be used in two or three ways, show that feature being used in all of those ways. Documentation seems to only cover the primary use case and leaves you to either run through trial and error or consult the user community. In terms of support, I have never actually had them solve any of my issues. I have always solved them myself and then provided the resolution to support."
"We have issues with the certificates. All authorization processes need certificates, however, every three months we needed to change certificates. This process iss complicated for us because Citrix does not have a not user-friendly interface and does not off user-friendly services. This needs a lot of improvement."
"The technical support has room for improvement."
"Integration with other third party providers and third party applications could be better because it can be a bit complex at present."
"It does not have a sandbox cloud service and antivirus. It should have on-prem or cloud sandboxing and antivirus."
