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."
"Software defined load balancing allows us to dynamically adjust and codify routing decisions. This speeds up development."
"It reduced the load on our main load balancers."
"The solution is user-friendly and efficient."
"The feature that I have found the most valuable is that it works for my use case of application load balancing. I'm using it for PeerSense, and it's easy enough for PeerSense."
"The most valuable feature of HAProxy is that its open source."
"I am also able to make configuration changes during the day, in production, with no worries of problems and/or downtime occurring."
"We don't have a problem with the user interface. it's good."
"We use it as a load balancer for our application servers."
 

Cons

"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"The support from A10 should be improved."
"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"While troubleshooting, we are having some difficulties. There are no issues when it is running; it is stable and very good; however, if there is a troubleshooting issue or an incident occurs, we will have issues because this is open-source."
"The configuration should be more friendly, perhaps with a Web interface. For example, I work with the ClusterControl product for Severalnines, and we have a Web interface to deploy the HAProxy load-balancer."
"If nbproc = 2, you will have two processes of HAProxy running. However, the stats of HAProxy will not be aggregated, meaning you don't really know the collective status in a single point of view."
"The solution's dashboards and reports could be improved."
"The only area that I can see needing improvement is the management interface, since it is pretty much all through the CLI or configuration. A GUI/web interface could be helpful for users who are not as experienced in the Linux shell. However, HAProxy does have another product that we evaluated called ALOHA, which has a web front-end, but we found it did not meet our needs."
"There is room for improvement in the pricing model. It could be cheaper."
"The configuration syntax is powerful yet can become overwhelming for newcomers; a more beginner-friendly interface or a native GUI without relying on third-party tools would ease the onboarding process."
"There are three main areas to improve: 1) Make remote management more modern by adding API. 2) Propose a general HA ​solution for HAProxy (no I'm using keepalived for this). 3) Thread option should be a bit more stable."
 

Pricing and Cost Advice

Information not available
"HAProxy is free software. There are optional paid products (support/appliances)."
"When it comes to pricing HAProxy is free."
"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"HAProxy is free in the initial offer. However, pricing can be improved."
"It is free of cost."
"HAProxy is free open-source software."
"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."
