AWS RDS — Managed Databases¶
AWSRDSAuroraDatabases 5 min read
Relational Database Service. Multi-AZ, Read Replicas, Aurora, backup, and performance tuning.
Supported Engines¶
- Aurora — AWS-native, 5× MySQL performance, up to 15 read replicas
- PostgreSQL / MySQL / MariaDB — open-source engines
- Oracle / SQL Server — enterprise, BYOL or included license
Multi-AZ and Read Replicas¶
aws rds create-db-instance \
--db-instance-identifier mydb \
--db-instance-class db.r6g.xlarge \
--engine aurora-postgresql \
--multi-az \
--allocated-storage 100
Multi-AZ = synchronous replication, automatic failover. Read Replicas = asynchronous, for read-heavy workloads.
Backup¶
- Automatic snapshots — 1–35 day retention
- Point-in-Time Recovery — restore to any point in time
- Aurora Backtrack — “undo” without restore
Summary¶
RDS eliminates DB ops overhead. For maximum performance, choose Aurora with Multi-AZ and Read Replicas.
