Kubernetes has made huge improvements in the ability to run stateful workloads including databases and message queues, but I still prefer not to run them on Kubernetes.

Postgres is what happens when tech gets so good, for so long, it becomes boring. Dope since the 80s. https://t.co/zeoagBfMvW

PostgreSQL for relational.
PromQL for monitoring.

Two big alignments across the industry.

I'm super curious, how many people have successfully migrated their databases from Oracle to Postgres in production? I'm talking 100% migration with Oracle being turned off at the end.
— Kelsey Hightower (@kelseyhightower) November 1, 2021

Kubernetes can only meet stateful services half way. We need direct changes in databases, message brokers, and other stateful systems if we want to see a future where Kubernetes becomes the preferred destination to run them. The @vectorizedio team is doing their part. https://t.co/w94Q56nnXM

Sometimes we work for a database and need to connect to another (#migration ;) so I explained to a colleague the difference between Oracle SERVICE_NAME and SID. Pasting it here in case it helps 🧵

Kubernetes Database Operator is useful for building scalable database servers as a database cluster. But migrating existing databases to k8s requires a lot of manual work due to having to create new artifacts.

At our next meetup, we'll demo an open-source tool to solve this. pic.twitter.com/o55vnyITV2
