RDS (Relational Database Service) is een managed database service — het voert relationele databases (PostgreSQL, MySQL, SQL Server, enz.) voor je uit en handelt operationele taken af (setup, backups, patching, scaling, failover) zodat jij je kunt concentreren op je applicatie in plaats van databasebeheer.
Wat RDS biedt: managed databases
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).
