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.

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 have reported an increase in revenue by around 5% on a year to year basis, since this solution was implemented."

"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."

"The ease of use of the configuration, and great documentation, are the most valuable features for us."

"It reduced the load on our main load balancers."

"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."

"Compared to the others in the market, such as Citrix and F5, the cost per performance for Aloha appliances is extremely low, and in our experience, the performance and reliability is better."

More HAProxy pros

Cons

"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 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."

"Pricing, monitoring, and reports can be improved."

"In my opinion, there are three main areas to improve: Make remote management more modern by adding API. Propose a general HA solution for HAProxy (now I'm using keepalived for this)."

"Sometimes it's challenging to get through the log, and you need a log to understand what is going on."

"The only area that I can see needing improvement is the management interface, since it is pretty much all through the CLI or configuration."

"I would like to see a two (or more) native cluster support without third parties or DNS manipulations."

"The deployment and configuration of HAProxy are not easy if we compare it with other solutions, such as F5."

"Full layer 7 SSL termination is limited to a single core, which is a problem."

"We need to handle new connections by dropping, or queuing them while the HAProxy restarts, and because HAProxy does not handle split config files."

Pricing and Cost Advice

Information not available

"HAProxy is free in the initial offer. However, pricing can be improved."

"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."

"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible."

"It is free of cost."

"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."

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

"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."

"HAProxy is free open-source software."

Reviews from Real Users

“Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind.” - Nathanel S., Platform Architect at SES

“I use HAProxy for individuals who can not buy low balancers. I built NFV in a box and send individuals a pathway into an HAProxy VM. The setup was not difficult; it usually takes a day to complete for a VPC. When it comes to pricing, HAProxy is free.” - Nasir O., Network & Cloud Architect at Koala Compute Inc.
