We asked business professionals to review the solutions they use. Here are some excerpts of what they said:

Pros
Helped us a lot with load balancing.Very stable.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.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.It has helped us to increase the resiliency of the application and the performance.It is the best product out there.Scalability is great. One of the best features of NetScaler is that it can scale out.This solution allows the user to easily scale out application delivery, and provides secure remote access.

It solves a problem for me where I can build files, not based on the health of the check, but rather the speed of the check.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.Advanced traffic rules, including stick tables and ACLs, which allow me to shape traffic while it's load balanced.Performance configuration options with threads, processes, and core stickiness are very valuable.The ability to handle a sequence of front- and back-ends gives the user the opportunity to send traffic through different services.We were able to use HAProxy for round robin with our databases, or for a centralized TCP connection in one host.It reduced the load on our main load balancers.We did not need technical support because the documentation is good.

Cons
Technical support sometimes takes a little longer because of the multilevel ticket priority.Does not include security. A web application firewall would be a nice addition.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.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 technical support has room for improvement.It can be difficult to setup.I would like to see more integration for single sign-on.Should offer more flexible cost-effective licensing for small to medium sized organizations.

The logging functionality could use improvement, as it is a little cryptic.There are three main areas to improve: 1) Make remote management more modern by adding API. 2) Propose a general HA ​solution for HAProxy (no I'm using keepalived for this). 3) Thread option should be a bit more stable.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 web stats UI, which provides the status of the health and numbers, could greatly benefit from having a RESTful interface to control the load-balanced nodes. Although there is a hack around the UI (by issuing a POST request to HAProxy with parameters), a RESTful interface would greatly improve the automation process (through Chef and Ansible).I would like to evaluate load-balancing algorithms other than round robin and SSL offloading. Also, it would be helpful if I could logically divide the HAProxy load-balancing into multiple entities so that I would install one HA Proxy LB application which could be used for different Web servers for different applications. I am not sure if these features are available.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.​It needs proper HTTP/2 support.​

Pricing and Cost Advice
We have a yearly licencing fee, and there are no additional costs.Ninety day free trial makes it easy to try out this solution.Licensing is adequate. I wanted to have a more prominent license, but until I do they don't give enough support. The additional cost would be too much.NetScaler does the same thing as an F5 and it's cheaper.You get the value for your money. There aren't any hidden fees.I do not have any experience with the pricing of the product.We are quite happy with price. It's not too high.We have been evaluating F5, Citrix, and other ADC products. Citrix is the most expense of all of them.

The only cost is for the image manager, who is responsible for uploading the image, and that is trivial.I think that the pricing is very fair, I would definitely recommend buying the Enterprise license.We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​.If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution.Very good value for the money. One of the simplest licensing schemes in this category of products.Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes.The price is well worth it. HAProxy Enterprise Edition paid for itself within months, simply due to the resiliency it brings. It was a bit more expensive than we were originally interested in paying, but we are thankful we chose to go with HAProxy.HAProxy is free software. There are optional paid products (support/appliances).
