We performed a comparison between Array APV Series, Citrix NetScaler, and HAProxy based on real PeerSpot user reviews.
Find out what your peers are saying about F5, Citrix, HAProxy and others in Application Delivery Controllers (ADC)."One of the most valuable features of this solution is the server load balancing. Something that sets this solution apart from other products is that the hardware has a much higher capacity than other vendors. That's the edge of Array Networks. Their technical support services are also very good."
"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 solution can scale."
"I found that the GUI was very easy to to navigate. If you were looking for something, it was fairly easy to find. There's a lot of third-party documentation and information available online as well."
"The solution improves security performance."
"The best feature of Citrix is its track record of stability in its features."
"Its flexibility, agility, and robustness are the most valuable. Its management and implementation are also quite easy."
"For NetScaler, our major use cases are database load balancing, PowerVPN VPN access gateway, WAF (Web Application Firewall), and content switching."
"The most valuable feature is the content switching."
"I can simplify configurations of many internal services (e.g. Web server configs) by moving some elements (like SSL) to HAProxy. I can also disable additional applications, like Varnish, by moving traffic shaping configurations to HAProxy."
"It is stable. Period. Will not fail unless you do something wrong."
"The feature that I have found the most valuable is that it works for my use case of application load balancing. I'm using it for PeerSense, and it's easy enough for PeerSense."
"The VRRP redundancy is also a mission-critical feature that works seamlessly. I can bring down a server live with minimal downtime because of this."
"The most valuable thing for me is TCP/IP Layer 4 stuff you can do with HAProxy. You can go down to the protocol level and make decisions on something."
"I have found HAProxy very helpful in replicating production environment architecture in a development and testing environment."
"HAProxy potentially has a good return on investment"
"The ease of use of the configuration, and great documentation, are the most valuable features for us."
"I would like to see more granular reporting and monitoring features, and I believe our clients want to see them as well. Also, SD-WAN would be a good addition."
"Development team's response time could be better."
"Should offer more flexible cost-effective licensing for small to medium sized organizations."
"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."
"Finding relevant documentation for learning NetScaler can be challenging, especially for beginners who prefer a web interface over command-line interfaces."
"We face challenges with the solution's firmware upgrades frequently."
"It can be difficult to setup."
"Technical support could be improved."
"Too many bugs in the software and it's always difficult when you need to update."
"It needs proper HTTP/2 support."
"HAProxy is very weak in the logging and monitoring part and requires improvement."
"We would like to see dynamic ACL and port update support. Our infrastructure relies on randomly allocated ports and this feature would allow us to update without restarting the process."
"I would like to see better search handling, and a user interface, with a complete functional graphical unit"
"Improving the documentation with multiple examples and scenarios would be beneficial. Most users encounter similar situations, so having a variety of scenarios readily available on the tool's website would be helpful. For instance, if I were part of the HAProxy team, I'd create a webpage with different scenarios and provide files for each scenario. This way, users wouldn't have to start from scratch every time."
"HAProxy could do with some good combination integrations."
"The solution can be improved by controlling TCP behavior better and mandating to clients what the expected outcome must be in order to avoid receiving contestant timeout logs."
"They should introduce one feature that I know many people, including me, are waiting for: HAProxy should have provide hot-swipe for back-end servers. Also, they need a more detailed GUI for monitoring and configuration."
