RONALDO DE MELO - PeerSpot reviewer
Sales Account Executive at l8
Efficient application security while optimizing connections
The initial setup is simple; it is not complex. The configuration itself is simple and can be done in a couple of hours. However, the migration of the system to A10 Networks takes longer due to critical applications. Clients prefer to move them one by one, which is why it takes a significant amount of time. The configuration itself is simple, especially for this application.

Handles high traffic efficiently and simplifies complex routing with rule-based logic
I think HAProxy is good as it stands now, but I believe there could be improvements. gRPC has recently been implemented, which is great, along with TLS 1.2 and 1.3 support, and HTTP 2.0 is also available. However, I'm unsure about the benchmark of those HTTP 2.0 requests on HAProxy. If there were any other protocol with better performance than HTTP 2.0, or perhaps mTLS and other similar features, including that in HAProxy would be really great. For improvements, I think that during setup and configuration, the steps provided are neat and clear. Anyone can easily install and configure it. There are many kernel tuning parameters also available, which is great. For specific improvement, in terms of logging, I think printing the full object of the request may help, or if there's a way to reference two requests, it would be beneficial to find a complete session history from a logged-in customer, as it would help analyze customer and user analytics.

Quotes from Members

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

Pros

"What I like about Lightning ADC, is that instead of having a big appliance sitting in front of the Kubernetes cluster, Lightning can pretty much go inside of Kubernetes."
"Our clients appreciate that this is a security enabled solution."
"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."
"Our clients have reported an increase in revenue by around 5% on a year to year basis, since this solution was implemented."
"The main difference between HAProxy and other solutions on the market is that it is open source."
"I am also able to make configuration changes during the day, in production, with no worries of problems and/or downtime occurring."
"With centralized SSL termination and automated renewals now in place, that time requirement has dropped to nearly zero hours, translating to dozens of hours saved per year."
"It is scalable."
"Load balancing is valuable, and we are also using the WAF feature."
"HAProxy has positively impacted my organization by making it easier for me to manage configurations; I put configuration files on the Ceph storage shared across the whole cluster, allowing me to write my configuration, change it easily in one place, and reload it."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"I can't speak to all of the HAProxy features because we don't use them all, but load balancing is very good."
 

Cons

"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"The support from A10 should be improved."
"The documentation is pretty much closed and I think A10 crashes sometimes because initially, I was not able to set up Lightning ADC."
"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"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."
"While troubleshooting, we are having some difficulties."
"HAProxy needs to improve its ability to handle a lot of connections, to be more like NGINX."
"I would like to see better search handling, and a user interface, with a complete functional graphical unit."
"The tech support is good however, there are sometimes delays in resolving issues because when there is a shift change there doesn't seem to be any communication between the support staff and we are constantly having to repeat our issues to the next person."
"From my point of view, the configuration should be more friendly, perhaps with a Web interface."
"The deployment and configuration of HAProxy are not easy if we compare it with other solutions, such as F5."
"An alerting system would be better as I need to check log files if any backend is down."
 

Pricing and Cost Advice

"HAProxy is an open-source solution."
"We are using HAProxy as an open-source."

"The product is open source."
"The licensing fee for the solution is $690 per unit annually."

"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."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
