Start with GCP managed Postgres alignment
If your application is already on AWS and you need a production-grade managed relational database with automatic failover, multi-AZ replication, and deep IAM integration, Amazon Aurora PostgreSQL is the default choice. Aurora's serverless v2 option eliminates capacity planning for variable-load applications. The cost is meaningful — Aurora is 3-5x more expensive than running PostgreSQL on EC2 directly — but the operational savings on patching, backups, and failover management are real for teams without dedicated database administrators.
