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 stable. Period. Will not fail unless you do something wrong."
"There are no issues when it is running; it is stable and very good."
"HAProxy has positively impacted my organization by making it easier for me to manage configurations; I put configuration files on the Ceph storage shared across the whole cluster, allowing me to write my configuration, change it easily in one place, and reload it."
"It is scalable."
"The licensing fee for the entire WAF solution is very affordable with Loadbalancer.org, and there are no separate charges for HAProxy and WAF."
"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."
"We were able to use HAProxy for round robin with our databases, or for a centralized TCP connection in one host."
"We use the solution for load balancing."
"It is a scalable product."
 

Cons

"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 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."
"​It needs proper HTTP/2 support.​"
"I would like to evaluate load-balancing algorithms other than round robin and SSL offloading."
"A significant area for improvement in HAProxy is its tenancy model; managing multiple environments can be challenging, especially with mergers, acquisitions, or domain changes."
"An alerting system would be better as I need to check log files if any backend is down."
"I would improve the web-based UI, but it’s a matter of personal preference."
"From my point of view, the configuration should be more friendly, perhaps with a Web interface."
"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."
"I use the open-source version of the product. I don't have experience with the licensed version of the solution."
"HAProxy is a free open-source solution."
"When it comes to pricing HAProxy is free."
"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 open-source software."
"HAProxy is an open-source solution."
"If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."
"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."
