Used for load balancing, but its dashboard and reporting could be improved
We use the solution for load balancing The solution's implementation and troubleshooting are not easy. The solution's dashboards and reports could be improved. I have been using HAProxy for 12 years. We didn’t face any issues with the solution’s stability. I rate the solution’s stability an…
Arjun Pandey - PeerSpot reviewer
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 improves our scalability and responsiveness services to meet our demanding customer requirements."
"The most important features would be the load-balancing of HTTP and TCP requests, according to multiple LB-algorithms (busyness, weighted-busyness, round robin, traffic, etc). Another important feature that we cannot live without is the username/passwd authentication for legacy systems that had none."
"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."
"Scalable and inexpensive."
"I am also able to make configuration changes during the day, in production, with no worries of problems and/or downtime occurring."
"It is stable. Period. Will not fail unless you do something wrong."
"Load balancing is valuable, and we are also using the WAF feature."
"The solution is effective in managing our traffic."
"It is a scalable product."
 

Cons

"The solution can be improved by controlling TCP behavior better and mandating to clients what the expected outcome must be in order to avoid receiving contestant timeout logs."
"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."
"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."
"HAProxy could do with some good combination integrations."
"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 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."
"We've changed solutions as it doesn't fit with our current needs."
"The visibility could be improved."
"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."
"HAProxy is free in the initial offer. However, pricing can be improved."
"The only cost is for the image manager, who is responsible for uploading the image, and that is trivial."
"Very good value for the money. One of the simplest licensing schemes in this category of products."
"We use NGINX as well. However, because the health checks are a paid feature, I like to avoid it whenever possible​."
"The licensing fee for the solution is $690 per unit annually."
"The product is open source."
"The tool is open-source."
"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."
