Used for load balancing, but its dashboard and reporting could be improved
We use the solution for load balancing The solution's implementation and troubleshooting are not easy. The solution's dashboards and reports could be improved. I have been using HAProxy for 12 years. We didn’t face any issues with the solution’s stability. I rate the solution’s stability an…

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

"​It has allowed us to evenly distribute the load across a number of servers, and check their health and automatically react to errors."
"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 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."
"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."
"We did not need technical support because the documentation is good."
"The support for all major Linux distros makes running and testing a breeze."
"The most valuable feature of HAProxy is that its open source."
"Load balancing is valuable, and we are also using the WAF feature."
"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 could do with some good combination integrations."
"The product does not have any new technologies."
"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)."
"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."
"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."
"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."
"HAProxy could improve by making the dashboards easier to use, and better reports and administration tickets."
"The solution can be improved by controlling TCP behavior better and mandating to clients what the expected outcome must be in order to avoid receiving contestant timeout logs."
"They could improve issues related to triggering generic deployments for the platform."
"The command line of HashiCorp Consul could be more intuitive to make it easier to use."
"Health check outputs are delayed sometimes."
 

Pricing and Cost Advice

"HAProxy is free open-source software."
"We are using HAProxy as an open-source."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"The tool is open-source."
"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."
"The licensing fee for the solution is $690 per unit annually."
"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."
"In case of budget constraints, we opt for the product's business support licenses and use an open-source version"
