RDBMS

RDS Postgres

Amazon RDS for PostgreSQL is a managed relational database service — AWS handles provisioning, patching, backups, and failover for a standard PostgreSQL instance.

What “managed” buys you:

Automated backups — point-in-time restore without hand-rolled scripts
Multi-AZ failover — a standby replica takes over automatically on failure
Read replicas — scale read traffic without touching the primary
Patching — minor version upgrades applied in a maintenance window

You still write standard Postgres SQL and connect with any Postgres driver — RDS just removes the server administration layer underneath it.
