Google Cloud SQL Auth Proxy
Securely connect to your Cloud SQL instances.
Overview
The Cloud SQL Auth proxy is a utility provided by Google Cloud that allows you to securely connect to your Cloud SQL instances. It works by creating a secure tunnel to the database, using IAM permissions to authorize connections. This removes the need for managing static IP addresses or complex SSL configurations.
✨ Key Features
- Secure, encrypted connections using TLS 1.3
- IAM database authentication
- No need for static IP allowlists
- Automatic mTLS encryption
- Can run as a binary or Docker container
🎯 Key Differentiators
- Focus on secure authentication and authorization via IAM
- Client-side proxy, not a connection pooler
- Deep integration with Google Cloud ecosystem
Unique Value: Provides a simple and secure method for connecting to Google Cloud SQL using IAM, abstracting away network security complexities.
