AWS RDS (Relational Database Service) manages your database (MySQL, PostgreSQL, MariaDB, SQL Server, Oracle). AWS handles patching, backups (35-day retention), failover to standby, monitoring. You provision instance size (db.t3.small to db.r6g.16xlarge), manage via console or AWS SDK, monitor performance. Mastery means understanding instance types, parameter groups, multi-AZ failover, backup strategies, query optimization, and cost optimization. Learning path: SQL basics (1 week) → RDS setup (1 week) → backups + monitoring (2 weeks) → multi-AZ + scaling (3 weeks).

AWS RDS Relational म्हणजे काय

AWS RDS (Relational Database Service) manages relational databases for you. Supports MySQL, PostgreSQL, MariaDB, SQL Server, and Oracle. AWS handles patching, backups (automated, 35-day retention), failover (multi-AZ), and monitoring. You choose instance type, define parameter groups, and manage via console. RDS is simpler than self-hosting. You don't patch OS, manage storage, or handle replication manually.

❓ FAQ

Should I use RDS or Aurora?
RDS: standard MySQL/PostgreSQL, cheaper upfront. Aurora: cloud-native, 5x faster, scales better, more expensive. Use RDS for small/medium; Aurora for scale.
What's Multi-AZ?
Multi-AZ: primary database in one Availability Zone, synchronous standby in another. On primary failure, RDS auto-failover to standby (<1 min). High availability.
How long does backup/restore take?
Automated backups: continuous incremental, kept 35 days. Restore: depends on data size (1GB = 1 min, typically). Manual snapshots: instant (point-in-time).
Can I upgrade database engine?
Yes, upgrade MySQL 5.7 → 8.0, PostgreSQL 12 → 15. Requires downtime (minor: seconds; major: minutes). Test in staging first.
What about database maintenance windows?
RDS performs backups and patching during maintenance window. Choose window (e.g., Sunday 3-4am) to minimize impact.
How much does RDS cost?
db.t3.micro: ~$0.017/hour (~$12/mo). db.r6g.xlarge: ~$1.50/hour (~$1000/mo). Storage: ~$0.10/GB/month. Multi-AZ: 2x price. Reserved instances: 30-70% discount.
Is RDS suitable for production?
Yes, standard for production. Multi-AZ for high availability, automated backups for recovery. Caveats: query optimization critical, scaling requires replicas (Aurora better).
