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

"Our clients appreciate that this is a security enabled solution."
"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."
"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."
"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."
"It is scalable."
"Stability is number one."
"It reduced the load on our main load balancers."
"I am also able to make configuration changes during the day, in production, with no worries of problems and/or downtime occurring."
"It is stable. Period. Will not fail unless you do something wrong."
"The solution is user-friendly and efficient."
"The most valuable feature of HAProxy is that its open source."
 

Cons

"The support from A10 should be improved."
"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"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."
"​It needs proper HTTP/2 support.​"
"Maybe HAProxy could be more modular."
"Improving the documentation with multiple examples and scenarios would be beneficial. Most users encounter similar situations, so having a variety of scenarios readily available on the tool's website would be helpful. For instance, if I were part of the HAProxy team, I'd create a webpage with different scenarios and provide files for each scenario. This way, users wouldn't have to start from scratch every time."
"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 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."
"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)."
"A significant area for improvement in HAProxy is its tenancy model; managing multiple environments can be challenging, especially with mergers, acquisitions, or domain changes."
