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

"The ability to handle a sequence of front- and back-ends gives the user the opportunity to send traffic through different services."
"I have found HAProxy very helpful in replicating production environment architecture in a development and testing environment."
"The ease of use of the configuration, and great documentation, are the most valuable features for us."
"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 feature of HAProxy is that its open source."
"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."
"Software defined load balancing allows us to dynamically adjust and codify routing decisions. This speeds up development."
"I can't speak to all of the HAProxy features because we don't use them all, but load balancing is very 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."
"The documentation is good."
 

Cons

"The product does not have any new technologies."
"We've changed solutions as it doesn't fit with our current needs."
"The GUI should be more responsive and show the detailed output of logs."
"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 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."
"We need to handle new connections by dropping, or queuing them while the HAProxy restarts, and because HAProxy does not handle split config files."
"The reconfigurability in terms of the tooling could be improved and maybe an editor plugin can be added."
"The logging functionality could use improvement, as it is a little cryptic."
"They could improve issues related to triggering generic deployments for the platform."
"Health check outputs are delayed sometimes."
"The command line of HashiCorp Consul could be more intuitive to make it easier to use."
 

Pricing and Cost Advice

"If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."
"When it comes to pricing HAProxy is free."
"I use the open-source version of the product. I don't have experience with the licensed version of the solution."
"HAProxy is free open-source software."
"HAProxy is a free open-source solution."
"It is free of cost."
"We are using HAProxy as an open-source."
"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
"In case of budget constraints, we opt for the product's business support licenses and use an open-source version"
