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."
"It is stable. Period. Will not fail unless you do something wrong."
"The licensing fee for the entire WAF solution is very affordable with Loadbalancer.org, and there are no separate charges for HAProxy and WAF."
"It improves our scalability and responsiveness services to meet our demanding customer requirements."
"Load balancing is valuable, and we are also using the WAF feature."
"Software defined load balancing allows us to dynamically adjust and codify routing decisions, which speeds up development."
"With each new release, I find very useful features and love each addition."
"It is a crucial tool in ensuring smooth service provision without any interruptions."
"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."
 

Cons

"The tool needs to incorporate better documentation and more example samples."
"HAProxy could do with some good combination integrations."
"Maybe HAProxy could be more modular."
"Pricing, monitoring, and reports can be improved."
"While troubleshooting, we are having some difficulties."
"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)."
"The tech support is good however, there are sometimes delays in resolving issues because when there is a shift change there doesn't seem to be any communication between the support staff and we are constantly having to repeat our issues to the next person."
"The solution's dashboards and reports could be improved."
"I would like to see better search handling, and a user interface, with a complete functional graphical unit."
 

Pricing and Cost Advice

"The tool is open-source."
"HAProxy is free in the initial offer. However, pricing can be improved."
"It is free of cost."
"HAProxy is an open-source solution."
"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
"The tool is open-source."
"We are using HAProxy as an open-source."
"When it comes to pricing HAProxy is free."
"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."
