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

"It is scalable."
"We definitely saw fewer employees needed and money saved; we achieved 100% money savings and fewer employees with very little maintenance required."
"It improves our scalability and responsiveness services to meet our demanding customer requirements."
"We use it as a load balancer for our application servers."
"HAProxy has positively impacted my organization because all of my applications are now centralized in one point, so I can manage it from my load balancer machine."
"Advanced traffic rules, including stick tables and ACLs, which allow me to shape traffic while it's load balanced."
"Load balancing is valuable, and we are also using the WAF feature."
"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."
"It is a scalable product."
 

Cons

"HAProxy is definitely a power-user tool. It is enormously scalable and flexible, but this can come at the cost of usability."
"There is room for improvement in the pricing model. It could be cheaper."
"The deployment and configuration of HAProxy are not easy if we compare it with other solutions, such as F5."
"The configuration should be more friendly, perhaps with a Web interface. For example, I work with the ClusterControl product for Severalnines, and we have a Web interface to deploy the HAProxy load-balancer."
"Dynamic update API. More things should be possible to be configured during runtime."
"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."
"The documentation is extremely detailed, but I think it could be restructured so it isn't so daunting for beginners."
"HAProxy could improve by making the dashboards easier to use, and better reports and administration tickets."
"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

"I use the open-source version of the product. I don't have experience with the licensed version of the solution."
"The tool is open-source."
"The only cost is for the image manager, who is responsible for uploading the image, and that is trivial."
"We are using HAProxy as an open-source."
"HAProxy is an open-source solution."
"HAProxy is free software. There are optional paid products (support/appliances)."
"It is free of cost."
"When it comes to pricing HAProxy is free."
"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."
