Where each one falls short

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

Amazon RDS

  • No super-user access or direct host connectivity limits advanced customization
  • Pricing unpredictable and expensive compared to GCP alternatives with equivalent features
  • Limited access to system procedures and tables requiring advanced permissions
  • No Oracle RAC (Real Application Clusters) support for high-availability Oracle deployments

Coder

  • Premium plan pricing is not published and requires contacting sales
  • Requires self-hosting and managing the underlying infrastructure, unlike fully managed cloud IDEs
  • High availability, audit logging, and RBAC are gated behind the paid Premium tier, so the free Community edition lacks enterprise controls
