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."
"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 have reported an increase in revenue by around 5% on a year to year basis, since this solution was implemented."
"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."
"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."
"The solution is user-friendly, works quickly and efficiently."
"Performance configuration options with threads, processes, and core stickiness are very valuable."
"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."
"Once the container is set up, the time it takes to deploy is typically under a minute, which gives me a full-blown solution with all the plugins and images that I am planning on using."
"HAProxy Enterprise Edition has been rock solid. We have essentially had no downtime caused by our load balancers in the last 10 months, because they’ve worked so well. Previously, our load balancers caused us multiple hours per year in downtime."
"It reduced the load on our main load balancers."
"Stability is number one."
 

Cons

"The documentation is pretty much closed and I think A10 crashes sometimes because initially, I was not able to set up Lightning ADC."
"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."
"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"The only area that I can see needing improvement is the management interface, since it is pretty much all through the CLI or configuration."
"The logging functionality could use improvement, as it is a little cryptic."
"The solution has bad performance issues."
"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 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."
"​It needs proper HTTP/2 support.​"
"Pricing, monitoring, and reports can be improved."
"From my point of view, the configuration should be more friendly, perhaps with a Web interface."

Do you recommend HAProxy?
I do recommend HAProxy for more simple applications or for companies with a low budget, since HAProxy is a free, open-source product. HAProxy is also a good choice for someone looking for a stable ...
What is your experience regarding pricing and costs for HAProxy?
Since we used the open-source version, we were not concerned about pricing, setup cost, or licensing.
What needs improvement with HAProxy?
HAProxy already provides many of the features that other solutions in the market are providing, such as Nginx, so I do not see much room for improvement.
