Duplicate SQL databaseRemove SQL database
Managed PostgreSQL with comparable vCPU and memory on each cloud. Cloudflare D1 has no instance size; it is priced from the rows read and written.

Keeps a standby copy in a second zone that takes over automatically if the first fails. Roughly doubles the database cost on AWS, Google Cloud and Azure.

Which is cheaper, Amazon RDS or Google Cloud SQL?

Monthly list prices in US East with the always-free allowances applied:

Usage per monthAmazon RDSGoogle Cloud SQLCheaper
Starter: burstable, about 2 GB memory, 20 GB storage$25.66$28.95Amazon RDS by $3.29
Production: 2 vCPU, 8 GB, 100 GB storage$141.44$118.18Google Cloud SQL by $23.26
High availability: 8 vCPU, 32 GB, 500 GB, standby in a second zone$1,154.52$979.42Google Cloud SQL by $175.10

Google Cloud SQL is cheaper for a production database in all 12 regions the calculator covers. The high-availability level uses RDS Multi-AZ (one standby) and Cloud SQL's regional HA configuration.

What are the key differences between Amazon RDS and Google Cloud SQL?

  • Pricing. RDS sells fixed instance sizes; Cloud SQL Enterprise prices any combination of vCPUs and memory, billed per second.
  • Storage. RDS gp3 costs less per GB-month than Cloud SQL SSD storage in US East.
  • SLA. RDS gives a single instance 99.5% and Multi-AZ 99.95%; Cloud SQL gives HA 99.95% and no SLA for single-zone instances.
  • Backups. Cloud SQL keeps automated backups up to 365 days; RDS up to 35 days.

Should you choose Amazon RDS or Google Cloud SQL?

Choose Amazon RDS if

  • you want cheaper storage for large databases
  • you want an SLA on a single, non-HA instance
  • your app runs on AWS

Choose Google Cloud SQL if

  • you need an unusual vCPU-to-memory ratio
  • you need backups kept longer than 35 days
  • your app runs on Google Cloud
