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."
"It allows you to secure the application while balancing the connections for many other customers, reducing CPU usage and server load."
"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 is scalable."
"The features I find valuable in this solution are session control which automatically disconnects users that forget to log off, and the ability to write rules to either allow or block certain file requests."
"HAProxy's TCP load balancer is excellent and super stable."
"HAProxy is highly customizable and will meet the business demands of most companies."
"The solution is effective in managing our traffic."
"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."
"It reduced the load on our main load balancers."
"We never have any downtime with it."
 

Cons

"We would like to see some improvement in the rapidity with which we can customize security facts within the solution."
"The support from A10 should be improved."
"A10 documentation is not as open and accessible as AWS and Azure documentation is."
"​It needs proper HTTP/2 support.​"
"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."
"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."
"The documentation is extremely detailed, but I think it could be restructured so it isn't so daunting for beginners."
"The solution's dashboards and reports could be improved."
"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."
"HAProxy is very weak in the logging and monitoring part and requires improvement."
"There is room for improvement in HAProxy's dynamic configuration."
 

Pricing and Cost Advice

Information not available
"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
"The product is open source."
"The licensing fee for the solution is $690 per unit annually."
"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"When it comes to pricing HAProxy is free."
"HAProxy is free open-source software."
"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."
