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."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"HAProxy's TCP load balancer is excellent and super stable."
"Others should try it out for sure. It’s a great solution backed by a very smart set of technical folks."
"The solution is effective in managing our traffic."
"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."
"HAProxy is definitely a dependable choice; the only thing that needs some attention is the initial learning curve, and when you get past that, it is a great tool to use and we are very happy with it."
"We don't have a problem with the user interface. it's good."
"Tech support is super-quick to respond, and always on target with answers specific to the current issue."
 

Cons

"The tool needs to incorporate better documentation and more example samples."
"The solution has bad performance issues."
"Maybe HAProxy could be more modular."
"We need to handle new connections by dropping, or queuing them while the HAProxy restarts, and because HAProxy does not handle split config files."
"There is room for improvement in the pricing model. It could be cheaper."
"The configuration syntax is powerful yet can become overwhelming for newcomers; a more beginner-friendly interface or a native GUI without relying on third-party tools would ease the onboarding process."
"The basic clustering is not usable in our very specific setup."
"A better GUI would be nice."
"The deployment and configuration of HAProxy are not easy if we compare it with other solutions, such as F5."
 

Pricing and Cost Advice

"The tool is open-source."
"HAProxy is an open-source solution."
"The product is open source."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"HAProxy is free open-source software."
"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."
"HAProxy is free in the initial offer. However, pricing can be improved."
"When it comes to pricing HAProxy is free."
