Cloud SQL Auth Proxy
A utility for connecting securely to your Cloud SQL instances
Cloud SQL Proxy is a secure connectivity utility that enables applications to connect to Google Cloud SQL instances without requiring manual configuration of SSL certificates or network access rules.

The proxy runs locally or alongside applications, exposing a local TCP port or Unix socket that applications can use as if they were connecting to a standard database. This abstraction simplifies development and deployment by allowing developers to use familiar database clients while the proxy handles authentication and encryption behind the scenes. It supports both public and private IP connections and can be deployed in environments such as local machines, virtual machines, Kubernetes clusters, or as a sidecar container. -
