Why we moved from AWS RDS to Postgres in Kubernetes

General storage IOPS scales with disk size, roughly and to a point. It's often cheaper and faster to increase the instance storage than move to EBS, prioritized or not.

Of course if you need to recover quickly in a disaster you'll want a hot standby or replica. Still may be cheaper than PIOPs. (Especially if you need HA anyway.)

Thanks for the reply.

You're saying it may well be cheaper to increase storage in order to get more IOPS than moving to an EBS-optimized instance type?

Regarding HA, not relevant for at this point (assuming I understood you correctly). We've only got a single primary and one replica, the latter being used primarily for analytics.
