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 is rock solid."

"We use it as a load balancer for our application servers."

"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."

"HAProxy positively impacted our organization by exceeding scalability expectations, initially projected at 200k requests but ultimately handling over 15 million transactions per second without any issues."

"It’s a reliable product with good technical support."

"The support for all major Linux distros makes running and testing a breeze."

"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."

"I have deployed over 50 instances of HAProxy over the past 15 years and never encountered any stability issues."

More HAProxy pros

"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."

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

"The tech support is good however, there are sometimes delays in resolving issues because when there is a shift change there doesn't seem to be any communication between the support staff and we are constantly having to repeat our issues to the next person."

"Maybe HAProxy could be more modular."

"HAProxy could improve by making the dashboards easier to use, and better reports and administration tickets."

"While the product is quite perfect, it could use more supervision and be more active. Also, more simplicity, more peripherals, and more scalability."

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

"Dynamic update API. More things should be possible to be configured during runtime."

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

"The tool is open-source."

"HAProxy is a free open-source solution."

"It is free of cost."

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

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

"The product is open source."

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

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

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."
