The short version

  • Each has a real cost: AWS API Gateway rEST APIs cost $3.50 per million calls against $1.00 for HTTP APIs, so the older and more featureful type is three and a half times dearer; Google Cloud SQL locked into Google Cloud ecosystem with limited cross-cloud portability
  • They diverge on capability: AWS API Gateway covers REST APIs, Google Cloud SQL covers High Availability.
  • Prices and features above were last checked on 30 August 2026.
