Mehdi El Filahi - PeerSpot reviewer
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.

Has an efficient key vault feature, but its integration capabilities need enhancement
I recommend HashiCorp Consul for beginners. It is a stable tool. The key-vault storage feature has significantly enhanced our configuration management process. We have maintained the secret software applications in the vault and retrieved the information from Kv. I rate the product a seven out of ten. It is good open-source software to be managed within the production.

Quotes from Members

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

Pros

"​​Reliability. HAProxy is the most reliable product I have ever used."
"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."
"Stability is number one."
"We did not need technical support because the documentation is good."
"The most important features would be the load-balancing of HTTP and TCP requests, according to multiple LB-algorithms (busyness, weighted-busyness, round robin, traffic, etc). Another important feature that we cannot live without is the username/passwd authentication for legacy systems that had none."
"Software defined load balancing allows us to dynamically adjust and codify routing decisions. This speeds up development."
"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 most valuable thing for me is TCP/IP Layer 4 stuff you can do with HAProxy. You can go down to the protocol level and make decisions on something."
"The documentation is good."
"The product's most valuable features are support for Service Mesh TLS and canary deployment."
"HashiCorp Consul's most valuable feature is the automation of many processes, which limits the errors from user interaction."
 

Cons

"HAProxy is very weak in the logging and monitoring part and requires improvement."
"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."
"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."
"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."
"HAProxy could improve by making the dashboards easier to use, and better reports and administration tickets."
"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."
"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)."
"There is no standardized document available. So, any individual has to work from scratch to work it out. If some standard deployment details are available, it would be helpful for people while deploying it. There should be more documentation on the standard deployment."
"The command line of HashiCorp Consul could be more intuitive to make it easier to use."
"They could improve issues related to triggering generic deployments for the platform."
"Health check outputs are delayed sometimes."
 

Pricing and Cost Advice

"Very good value for the money. One of the simplest licensing schemes in this category of products."
"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
"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 licensing fee for the solution is $690 per unit annually."
"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."
"It is free of cost."
"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."
"When it comes to pricing HAProxy is free."
"In case of budget constraints, we opt for the product's business support licenses and use an open-source version"
