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

"Others should try it out for sure. It’s a great solution backed by a very smart set of technical folks."

"HAProxy potentially has a good return on investment."

"The most valuable feature of HAProxy is that its open source."

"We did not need technical support because the documentation is good."

"HAProxy is highly customizable and will meet the business demands of most companies."

"Performance configuration options with threads, processes, and core stickiness are very valuable."

"HAProxy is rock solid."

"The ability to handle a sequence of front- and back-ends gives the user the opportunity to send traffic through different services."

More HAProxy pros

"It is a scalable product."

Cons

"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."

"We've changed solutions as it doesn't fit with our current needs."

"The solution has bad performance issues."

"An alerting system would be better as I need to check log files if any backend is down."

"The visibility could be improved."

"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)."

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

"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."

More HAProxy cons

"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

"It is free of cost."

"The only cost is for the image manager, who is responsible for uploading the image, and that is trivial."

"HAProxy is free open-source software."

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

"The tool is open-source."

"The licensing fee for the solution is $690 per unit annually."

"If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."

More HAProxy pricing and cost advice

"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."
