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

"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."
"Tech support is super-quick to respond, and always on target with answers specific to the current issue."
"Four days ago, I had an inundation in my informatic room, and there was no interruption of service, because HAProxy is an excellent cluster solution."
"We did not need technical support because the documentation is good."
"HAProxy potentially has a good return on investment."
"The VRRP redundancy is also a mission-critical feature that works seamlessly. I can bring down a server live with minimal downtime because of this."
"Since the deployment is very easy and the open-source functionality saves a huge amount of cost in terms of project deployment."
"Others should try it out for sure. It’s a great solution backed by a very smart set of technical folks."
"It is a scalable product."
 

Cons

"While troubleshooting, we are having some difficulties."
"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."
"HAProxy could do with some good combination integrations."
"Full layer 7 SSL termination is limited to a single core, which is a problem."
"Documentation could be improved."
"Maybe HAProxy could be more modular."
"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."
"We would like to see dynamic ACL and port update support. Our infrastructure relies on randomly allocated ports and this feature would allow us to update without restarting the process."
"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

"If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."
"HAProxy is an open-source solution."
"We are using HAProxy as an open-source."
"I use the open-source version of the product. I don't have experience with the licensed version of the solution."
"When it comes to pricing HAProxy is free."
"It is free of cost."
"HAProxy is free in the initial offer. However, pricing can be improved."
"The product is open source."
"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."
