A simple solution that works as a proxy server and load balancer
I used the solution to build a project's proxy server and load balancer I found Envoy simple to use compared to alternatives like Traefik. The tool needs to incorporate better documentation and more example samples.  I haven't contacted the tool's support team.  I chose Envoy for the POC…

Handles high traffic efficiently and simplifies complex routing with rule-based logic
I think HAProxy is good as it stands now, but I believe there could be improvements. gRPC has recently been implemented, which is great, along with TLS 1.2 and 1.3 support, and HTTP 2.0 is also available. However, I'm unsure about the benchmark of those HTTP 2.0 requests on HAProxy. If there were any other protocol with better performance than HTTP 2.0, or perhaps mTLS and other similar features, including that in HAProxy would be really great. For improvements, I think that during setup and configuration, the steps provided are neat and clear. Anyone can easily install and configure it. There are many kernel tuning parameters also available, which is great. For specific improvement, in terms of logging, I think printing the full object of the request may help, or if there's a way to reference two requests, it would be beneficial to find a complete session history from a logged-in customer, as it would help analyze customer and user analytics.

Quotes from Members

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

Pros

"I found Envoy simple to use compared to alternatives like Traefik."
"Four days ago, I had an inundation in my informatic room, and there was no interruption of service, because HAProxy is an excellent cluster solution."
"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 support for all major Linux distros makes running and testing a breeze."
"The solution is user-friendly, works quickly and efficiently."
"The technical support has been, in one word, perfect. Every time I call, I’m on the phone with a representative within five minutes who is highly skilled and willing to help, whether in the case of critical issues or simple advice."
"Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind."
"The features I find valuable in this solution are session control which automatically disconnects users that forget to log off, and the ability to write rules to either allow or block certain file requests."
"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."
 

Cons

"The tool needs to incorporate better documentation and more example samples."
"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 only area that I can see needing improvement is the management interface, since it is pretty much all through the CLI or configuration."
"In my previous job we had some stability issues related to configuration and compatibility with other products."
"Sometimes it's challenging to get through the log, and you need a log to understand what is going on. It isn't easy to map the logging with the documentation, and every time I read the log, I have to pull out the documentation to understand what I'm reading."
"The solution has bad performance issues."
"While the product is quite perfect, it could use more supervision and be more active. Also, more simplicity, more peripherals, and more scalability."
"We need to handle new connections by dropping, or queuing them while the HAProxy restarts, and because HAProxy does not handle split config files."
"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."
 

Pricing and Cost Advice

"The tool is open-source."
"HAProxy is an open-source solution."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"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."
"The tool is open-source."
"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."
"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
"I use the open-source version of the product. I don't have experience with the licensed version of the solution."
"HAProxy is free software. There are optional paid products (support/appliances)."
