Percona Kubernetes Operator

Pros: It's very easy to use and can do fast deployment.
Reliable and fully automated with high available DB lifecycle management solution.

Cons: No cons, Deployment and management are excellent and 100% accurate!

Overall: My overall experience has been excellent. Community has been really helpful. Easy and fast deployment.

Pros: Great tool to simplify complex Kubernetes deployments, Percona XtraBackup enables synchronous multi-primary replication.

Cons: The tool is new and isn't very flexible if moving form an existing technology so it would be better to check compatibility before using this.

Overall: The overall experience so far has been really great, the community forums, although small, is very helpful to get solutions for common issues.

Pros: Easy and fast deployment. A reliable, fully automated, high-available db lifecycle management solution. As they say "The Operator simplifies the deployment and management of the Percona XtraDB Cluster in Kubernetes-based environments", 100% accurate!

Cons: Percona XtraDB Cluster have some differences compared to "traditional" MySQL solution, so be sure to check these out before implementing the technology. We had some hard times trying to use it combined with pre-existing techs like WordPress, Magento, etc. Also the k8s environment features can have an impact on it, like the storage solutions. Be sure to match the requirements with the specific use case.

Overall: For a long time we struggled finding a viable solution to migrate our existing db workloads inside Kubernetes to leverage its benefits across our entire infrastructure (cloud native and multi-cloud). The state of db inside k8s is always been a critical topic. We started testing and using Kubernetes during it's early state, it's been always great at stateless workloads but using it with stateful apps was a pain. It got better with storage development and improvements. Before "operators era" proper db workloads required manual management, of course that easily raised administrative overhead. Then the future started to be brighter with the introduction of operators and the "official" Oracle's MySQL Operator, then Presslab's one, finally Percona's operator. With the last one we was able, for the first time, to ship production db workloads. We started with non-critical ones and after not much time we was "all-in" with all db workloads in Kubernetes. We had a very great time with Percona Kubernetes Operator for Percona XtraDB Cluster.

Pros: It is very handy in single region cluster scenario like single EKS or GKE cluster. You have proxysql or haproxy configured which I like very much.

Cons: I tried to use in multi region clusters but it does not support it. So I had to setup everything without operator on more than one cluster.

Overall: I like this kind of software, however at this point does not satisfy me due to lack of multi-region feature.
