At smaller scale, managed databases usually feel interchangeable.
The application works.
Queries run.
Everything seems fine.
But once workloads grow and infrastructure costs start increasing, database discussions become much more operational than people initially expect.
Storage performance.
IOPS limits.
Latency.
Cost scaling.
That’s usually where infrastructure tradeoffs start becoming much more visible.
The pricing usually looks straightforward until higher performance tiers start becoming necessary.
In practice, performance discussions usually turn into infrastructure efficiency discussions pretty quickly.
I found this benchmark useful because it compares AWS RDS and Civo Postgres from both the performance and operational cost perspective instead of only comparing monthly cost numbers:

As database workloads scale, infrastructure cost and performance tradeoffs become increasingly visible. Managed databases that seem interchangeable at small scale diverge significantly when IOPS limits, storage performance, and latency requirements grow. A benchmark comparing AWS RDS and Civo Postgres from both performance and operational cost perspectives is highlighted as a useful resource for evaluating these tradeoffs.
