A Case for Databases on Kubernetes from a Former Skeptic - The New Stack

Kubernetes is everywhere. Transactional apps, video streaming services and machine learning workloads are finding a home on this ever-growing platform. But what about databases? If you had asked me this question five years ago, the answer would have been a resounding “No!” — based on my experience in development and operations. In the following years, as more resources emerged for stateful applications, my answer would have changed to “Maybe,” but always with a qualifier: “It’s fine for development or test environments…” or “If the rest of your tooling is Kubernetes-based, and you have extensive experience…”

But how about today? Should you run a database on Kubernetes? With complex operations and the requirements of persistent, consistent data, let’s retrace the stages in the journey to my current answer: “In a cloud native environment? Yes!

“Kubernetes is everywhere” is a very bad way of starting an article because it’s not a factual statement.

Started reading but the “former skeptic” thing is not visible to me. I’m seeing masked fanboyism only, so far at least.

I understand that it may be not the best way of starting the article, but if you are developer inside the cloud native bubble it will make all the sense when reading it.

Maybe if it had been complemented with something in the likes of In a cloud native world Kubernetes is everywhere then readers that are not deep inside the cloud native bubble would not feel it as an overstatement.

He explains why he is a former skeptic, you just need to read the article. He does it in the introduction and later here:

My hopes of running a database on Kubernetes came roaring back. Could Cassandra deal with the ephemeral nature of containers? At the time, it felt like a begrudging “I guess?“. It seemed possible, but there were significant gaps in the tooling. To take this to production, I’d need a team of Kubernetes and Cassandra veterans, plus a suite of tooling and runbooks to fill in the operational gaps.

The author is on the K8ssandra project, its a MVP for the Cassandra community and works at DataStax, therefore I understand that he is so enthusiastic about what he is talking about, after all he is a Developer Advocate for Cassandra.

I learned something from the article, but I am a fan of Docker and Kubernetes and I considered to be a DevOps before I came into API security, therefore I have a little of the cloud native bubble inside me :slight_smile:

I’ve still yet to ever touch kubernates other than articles saying how horrible it was to build a fake type system in it to work around Golang’s limitations. I’m still not entirely sure what it does, something like docker swarm but more, or… Lol, I just need to look in to it someday.
