RDS (Relational Database Service) è un servizio di database gestito — esegue database relazionali (PostgreSQL, MySQL, SQL Server, ecc.) per te, gestendo i compiti operativi (setup, backup, patching, scaling, failover) in modo che tu possa concentrarti sulla tua applicazione, non sull'amministrazione del database.
Cosa fornisce RDS: database gestiti
RDS runs RELATIONAL DATABASES and MANAGES the operational burden for you:
→ SETUP — provision a database in minutes
→ BACKUPS — automated backups + point-in-time recovery
→ PATCHING — handles software updates/security patches
→ SCALING — resize compute/storage; read replicas
→ HIGH AVAILABILITY — Multi-AZ failover (standby in another zone)
→ MONITORING — built-in metrics
→ vs running a database YOURSELF on EC2 (you'd manage all of the above manually).
