We performed a comparison between A10 Networks Lightning ADC, 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)."Our clients appreciate that this is a security enabled solution."
"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."
"What I like about Lightning ADC, is that instead of having a big appliance sitting in front of the Kubernetes cluster, Lightning can pretty much go inside of Kubernetes."
"It is the best product out there."
"My clients use it for load balancing."
"The most valuable feature is the content switching."
"The maintenance of the solution is not complex."
"Scalability is great. One of the best features of NetScaler is that it can scale out."
"I can turn on features without actually owning a license. I can test them out, I can use them for a while, and then I can be licensed up. That's awesome. I don't have to have a license immediately before I can start to deploy things rapidly, rapid deployment is a plus."
"NetScaler Gateway: Why? Availability/Security: We delivered more than 200 applications thru Xenapp. This feature give us the possibility to deliver the applications anywhere. Currently, 30% of access is made through our NetScaler Gateway (Internet connections)."
"It is a stable solution. It crashed only once, four years ago...There is a return on investment using the solution."
"Performance configuration options with threads, processes, and core stickiness are very valuable."
"We were able to use HAProxy for round robin with our databases, or for a centralized TCP connection in one host."
"Stability is number one."
"The support for all major Linux distros makes running and testing a breeze."
"I estimate that this product has saved our company hundreds, if not thousands, of dollars in possible downtime from previous load balancers. We make a lot of our money from online sales, so it is critical to have 99.9% uptime."
"I have found HAProxy very helpful in replicating production environment architecture in a development and testing environment."
"We don't have a problem with the user interface. it's good."
"The ability to handle a sequence of front- and back-ends gives the user the opportunity to send traffic through different services."
"The support from A10 should be improved."
"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"The setup for Citrix NetScaler has room for improvement. It could be easier."
"The only thing customers told me that could be improved is that they would like to be able to purchase and receive the products in one box, rather than two boxes. This is something related to marketing, though."
"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."
"The technical support could be improved. They do not respond or assist customers in a timely manner."
"We face challenges with the solution's firmware upgrades frequently."
"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."
"Reducing the overhead required for AppFlow data collection, specifically for HDX Insight, would be a huge improvement."
"The licensing model and technical support of the solution could be improved."
"Maybe HAProxy could be more modular."
"The configuration should be more friendly, perhaps with a Web interface. For example, I work with the ClusterControl product for Severalnines, and we have a Web interface to deploy the HAProxy load-balancer."
"We need to handle new connections by dropping, or queuing them while the HAProxy restarts, and because HAProxy does not handle split config files."
"The logging functionality could use improvement, as it is a little cryptic."
"Documentation could be improved."
"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."
"The basic clustering is not usable in our very specific setup. The clustering is mainly a configuration replication and is great in a case of active-passive usage. In the case of an active-active (or with more than two nodes) where the configuration is not fully identical, it cannot be used as-is."
"HAProxy could improve by making the dashboards easier to use, and better reports and administration tickets."
