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

"The feature that I have found the most valuable is that it works for my use case of application load balancing. I'm using it for PeerSense, and it's easy enough for PeerSense."
"We definitely saw fewer employees needed and money saved; we achieved 100% money savings and fewer employees with very little maintenance required."
"We don't have a problem with the user interface. it's good."
"​It has allowed us to evenly distribute the load across a number of servers, and check their health and automatically react to errors."
"HAProxy potentially has a good return on investment"
"The most valuable thing for me is TCP/IP Layer 4 stuff you can do with HAProxy. You can go down to the protocol level and make decisions on something."
"Tech support is super-quick to respond, and always on target with answers specific to the current issue."
"We use the solution for load balancing."
"It is a scalable product."
 

Cons

"There are three main areas to improve: 1) Make remote management more modern by adding API. 2) Propose a general HA ​solution for HAProxy (no I'm using keepalived for this). 3) Thread option should be a bit more stable."
"Pricing, monitoring, and reports can be improved."
"Documentation could be improved."
"I would like to see better search handling, and a user interface, with a complete functional graphical unit"
"HAProxy is very weak in the logging and monitoring part and requires improvement."
"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."
"The GUI should be more responsive and show the detailed output of logs."
"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."
"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

"HAProxy is free software. There are optional paid products (support/appliances)."
"HAProxy is an open-source solution."
"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​."
"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."
"If you don't have expertise then go with the licensed version. Otherwise, open-source is the best solution."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"The only cost is for the image manager, who is responsible for uploading the image, and that is trivial."
"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."
