The short version

  • Each has a real cost: Google Cloud SQL locked into Google Cloud ecosystem with limited cross-cloud portability; Terraform hCL syntax requires learning a domain-specific language with limited GUI alternatives
  • They diverge on capability: Google Cloud SQL covers High Availability, Terraform covers Infrastructure as code.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Google Cloud SQL

  • Locked into Google Cloud ecosystem with limited cross-cloud portability
  • Pay-as-you-go pricing can become expensive with unpredictable workloads
  • Limited customization options compared to self-managed databases

Terraform

  • HCL syntax requires learning a domain-specific language with limited GUI alternatives
  • State file management is complex, especially at scale with multiple workspaces
  • terraform import workflow is fiddly and must be done one resource at a time
  • No native error handling or try-catch capabilities like traditional programming languages
  • No automatic rollback capability - must manually delete and re-run if needed
