About:
Cloud SQL Proxy provides secure access to your Cloud SQL instances by handling authentication and encryption. It allows you to connect to your database using standard networking without managing IP allowlists or SSL certificates. The proxy automatically manages IAM authentication and credential rotation for enhanced security.
Key Features:
  • Automatic IAM authentication
  • Encrypted connections without manual certificate management
  • Supports multiple database engines (MySQL, PostgreSQL, SQL Server)
  • Works with both public and private IP instances
Use Cases:
  • Connecting applications running on Google Cloud to Cloud SQL databases
  • Local development against Cloud SQL instances without exposing public endpoints
  • Containerized applications requiring secure database access
Alternatives:
  • pgcli – pgcli is a CLI client only, while cloud-sql-proxy provides secure connectivity layer
  • stunnel – stunnel provides generic SSL tunneling but lacks Cloud SQL specific authentication
