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…

Useful for for small and quick load-balancing tasks
What I like best about the product is its simplicity and speed. When you need to set up a load balancer quickly, HAProxy offers options like sticky sessions and round-robin. It's also fast to configure, including adding SSL for security. While it may have fewer options than other solutions like F5, HAProxy gets the job done for basic load-balancing tasks. The reliability features of HAProxy were particularly useful in a scenario where I needed to test load balancing between two Tomcats. Since these domains were inaccessible, I set up a third Docker with HAProxy, which had access to the Tomcat domains. I then configured HAProxy to handle the load balancing. This setup allowed the client to interact with HAProxy. The solution's integration with other elements is easy.

Pros

"I found Envoy simple to use compared to alternatives like Traefik."
"What I like best about the product is its simplicity and speed. When you need to set up a load balancer quickly, HAProxy offers options like sticky sessions and round-robin. It's also fast to configure, including adding SSL for security. While it may have fewer options than other solutions like F5, HAProxy gets the job done for basic load-balancing tasks."
"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."
"​​Reliability. HAProxy is the most reliable product I have ever used."
"It improves our scalability and responsiveness services to meet our demanding customer requirements."
"HAProxy Enterprise Edition has been rock solid. We have essentially had no downtime caused by our load balancers in the last 10 months, because they’ve worked so well. Previously, our load balancers caused us multiple hours per year in downtime."
"HAProxy's TCP load balancer is excellent and super stable."
"We did not need technical support because the documentation is good."
 

Cons

"The tool needs to incorporate better documentation and more example samples."
"HAProxy could improve by making the dashboards easier to use, and better reports and administration tickets."
"The reconfigurability in terms of the tooling could be improved and maybe an editor plugin can be added."
"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."
"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."
"Improving the documentation with multiple examples and scenarios would be beneficial. Most users encounter similar situations, so having a variety of scenarios readily available on the tool's website would be helpful. For instance, if I were part of the HAProxy team, I'd create a webpage with different scenarios and provide files for each scenario. This way, users wouldn't have to start from scratch every time."
"Documentation could be improved."
"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)."
"We would like to see dynamic ACL and port update support. Our infrastructure relies on randomly allocated ports and this feature would allow us to update without restarting the process."
 

Pricing and Cost Advice

"The tool is open-source."
"HAProxy is free software. There are optional paid products (support/appliances)."
"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"The product is open source."
"HAProxy is a free open-source solution."
"I use the open-source version of the product. I don't have experience with the licensed version of the solution."
"It is free of cost."
"HAProxy is free open-source software."
