It sounds pretty simple and enticing. Any problems convincing the team of this route?





Speaking from experience..

This is fine if you have a small single node database that can have some downtime. Once you need replicas, to fit your database in ram for performance, or reliability with a hot standby for failovers it becomes a lot more complicated.

You should consider what (if anything) you miss out on by just running in a single vm that you can scale out much easier down the road should you need to. Alternatively pay extra for a hosted solution that simplifies those steps further.


> single vm that you can scale out much easier

I’m not sure how experience could lead you to this conclusion. This wouldn’t work for any of our production needs.


Historically speaking, convincing anyone to run data stores on k8s is a giant pain. This isn't helped by all the mythology around "k8s is great for stateless" further promoted by folks like Kelsey Hightower who firmly believes that one should rely on the cloud provider's data stores.

This is great for the cloud provider as those are high margin services, I for one would rather have a single orchestration API that I have to interact with, that being the one offered by k8s. All the benefits of running workloads in k8s apply equally to data stores. Cattle, not pets. If your data store needs coddling then it's a pet and you're doing it wrong.
