I think that shouldn’t cause much troubles in DO. I had it running for a while without the prometheus operator, and I didn’t have any issue.

In the beginning I was even running everything on a one $10/mo “cluster” (cheapest DO offers). Even Postgres and Redis, all inside the cluster.

As I got more customers, I needed something less risky, so added more nodes, and moved the database out.

But to be honest even the 1 instance $10 cluster was fine.
