RDS (Relational Database Service) एक managed database service है — यह आपके लिए relational databases (PostgreSQL, MySQL, SQL Server, आदि) चलाता है, operational कार्यों (setup, backups, patching, scaling, failover) को संभालता है ताकि आप database administration नहीं, बल्कि अपने application पर ध्यान केंद्रित करें।
RDS क्या प्रदान करता है: 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).
