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.

Provides a unique advantage by offering a global view for all workloads and clusters within the mesh but lack of a robust community for open-source support
There are a number of areas where Kong Kuma can improve. One is in terms of product delivery, such as Helm charts. There are a lot of gaps in the Helm charts currently. Another is in terms of the default monitoring and logging setup. It is not as production-ready as it could be. By default, Kuma comes with Loki, Yagger, and Prometheus to monitor the control plane and data plane, but the unified dashboarding and logging solution should be closer to production-grade. It is good for trying out the product, but I would not recommend taking it to production without setting up your own monitoring and logging solution. Additionally, Kuma recently released Fivecarless Mesh, which was built on top of Envoy. The challenge with this is that it adds overhead. If you want to run 100 containers in production, you will actually need to run 200 containers because you need to run one sidecar container per pod. Overall, I think Kong Kuma is a moderate product, but I would not personally recommend it for production use.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"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."
"We did not need technical support because the documentation is good."
"It solves a problem for me where I can build files, not based on the health of the check, but rather the speed of the check."
"Having the right load balancing solution – which is what HAProxy is – and protection in place gives organizations peace of mind."
"It improves our scalability and responsiveness services to meet our demanding customer requirements."
"We use it as a load balancer for our application servers."
"It improves our scalability and responsiveness services to meet our demanding customer requirements."
"HAProxy is definitely a dependable choice; the only thing that needs some attention is the initial learning curve, and when you get past that, it is a great tool to use and we are very happy with it."
"It is a scalable product."
 

Cons

"I would like to see a two (or more) native cluster support without third parties or DNS manipulations."
"HAProxy could do with some good combination integrations."
"The logging functionality could use improvement, as it is a little cryptic."
"From my point of view, the configuration should be more friendly, perhaps with a Web interface."
"The reconfigurability in terms of the tooling could be improved and maybe an editor plugin can be added."
"Pricing, monitoring, and reports can be improved."
"They should introduce one feature that I know many people, including me, are waiting for: HAProxy should provide hot-swipe for back-end servers, no downtime while shifting back-end servers."
"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."
"The initial setup is complicated. Although Kuma has its own CLI, CTL, and they say to use their CLI, if I have to build a generic solution, my personal preference would be to use Helm or another similar solution other than Kuma. If you have your own library CLI, it becomes hard for others to adopt it. For example, if I have to write some automation, infrastructure automation, I can't just use Kuma. I have to change my code to use Kuma's CTL, which is unfair because it doesn't make sense. It doesn't fit with my current automation structure. I have to do something extra, something additional, which I really don't like."
 

Pricing and Cost Advice

"HAProxy is an open-source solution."
"I think that the pricing is very fair, I would definitely recommend buying the Enterprise license."
"HAProxy is a free open-source solution."
"It is free of cost."
"The product is open source."
"I use the open-source version of the product. I don't have experience with the licensed version of the solution."
"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."
"HAProxy is free software. There are optional paid products (support/appliances)."
"I have tried for my personal research and all those things. I have tried only the open-source version. So, for me, it was always free."

Questions from the Community

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.
