Why teams migrate from Cloud SQL to RDS
Good fit when
- +Teams moving database workloads to AWS alongside compute migrations.
- +Organizations wanting RDS features like Multi-AZ, read replicas, or Aurora compatibility.
- +Teams consolidating data services within AWS.
Strengths
- RDS offers more instance types and storage options.
- Multi-AZ deployments and cross-region read replicas are mature.
- Deep integration with AWS IAM, VPC, and CloudWatch.
Tradeoffs
- Cloud SQL's simpler configuration model is replaced by more granular RDS options.
- Parameter groups and option groups add configuration complexity.
- IAM database authentication setup differs from Cloud SQL IAM auth.
Migration notes
- Use pg_dump/pg_restore or mysqldump for data transfer.
- Consider AWS DMS for continuous replication during cutover.
- Remap connection strings, security groups, and subnet groups.
- Verify PostgreSQL extension and MySQL plugin compatibility.
