What a managed database costs across compute, storage and IO.
Database bills are dominated by compute, so right-sizing the instance and adding replicas only when needed beats micro-optimising storage. Compare a raw VM on the container hosting calculator.

Mostly the instance size (vCPU and RAM), then storage and backups, then options like replicas, multi-AZ failover and provisioned IOPS. Managed services add a premium over self-hosting for handling patching and failover.
Managed saves engineering time on backups, upgrades and failover — worth the premium for most teams. Self-hosting on a plain VM is cheaper per GB but you own the on-call. The right answer depends on your team, not just the price.
