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

"Overall, it's a good solution."

"I have found HAProxy very helpful in replicating production environment architecture in a development and testing environment."

"Performance configuration options with threads, processes, and core stickiness are very valuable."

"I can simplify configurations of many internal services (e.g. Web server configs) by moving some elements (like SSL) to HAProxy. I can also disable additional applications, like Varnish, by moving traffic shaping configurations to HAProxy."

"I estimate that this product has saved our company hundreds, if not thousands, of dollars in possible downtime from previous load balancers. We make a lot of our money from online sales, so it is critical to have 99.9% uptime."

"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."

"What I like best about the product is its simplicity and speed. When you need to set up a load balancer quickly, HAProxy offers options like sticky sessions and round-robin. It's also fast to configure, including adding SSL for security. While it may have fewer options than other solutions like F5, HAProxy gets the job done for basic load-balancing tasks."

"Reliability. HAProxy is the most reliable product I have ever used."

More HAProxy pros

"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."

"Sometimes it's challenging to get through the log, and you need a log to understand what is going on. It isn't easy to map the logging with the documentation, and every time I read the log, I have to pull out the documentation to understand what I'm reading."

"The only area that I can see needing improvement is the management interface, since it is pretty much all through the CLI or configuration. A GUI/web interface could be helpful for users who are not as experienced in the Linux shell. However, HAProxy does have another product that we evaluated called ALOHA, which has a web front-end, but we found it did not meet our needs."

"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."

"The product does not have any new technologies."

"HAProxy needs to improve its ability to handle a lot of connections, to be more like NGINX."

"The solution's dashboards and reports could be improved."

"I would like to see better search handling, and a user interface, with a complete functional graphical unit."

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

"It is free of cost."

"When it comes to pricing HAProxy is free."

"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 free software. There are optional paid products (support/appliances)."

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

"Test/lab virtual machines can be installed without a licence. They can't be used for performance testing but otherwise behave like production nodes."

"Very good value for the money. One of the simplest licensing schemes in this category of products."

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."
