We performed a comparison between HAProxy and HashiCorp Consul based on real PeerSpot user reviews.
Find out in this report how the two Service Mesh solutions compare in terms of features, pricing, service and support, easy of deployment, and ROI."Reliability. HAProxy is the most reliable product I have ever used."
"I can't speak to all of the HAProxy features because we don't use them all, but load balancing is very good."
"The anti-DDOS PacketShield filtering solution (embedded in the physical appliances) as well as the BGP route injection are great features and heavily used."
"We use it as a load balancer for our application servers."
"Stability is number one."
"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."
"Performance configuration options with threads, processes, and core stickiness are very valuable."
"Tech support is super-quick to respond, and always on target with answers specific to the current issue."
"The product's most valuable features are support for Service Mesh TLS and canary deployment."
"The documentation is good."
"HashiCorp Consul's most valuable feature is the automation of many processes, which limits the errors from user interaction."
"Maybe HAProxy could be more modular."
"The reconfigurability in terms of the tooling could be improved and maybe an editor plugin can be added."
"It needs proper HTTP/2 support."
"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."
"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)."
"The GUI should be more responsive and show the detailed output of logs."
"Health check outputs are delayed sometimes."
"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."
