Secure, IAM‑Based Cloud SQL Connections with the Auth Proxy on Compute Engine
Eliminate SSL certificates and IP whitelists for Cloud SQL by using the Auth Proxy on Compute Engine. A step‑by‑step guide shows how to set up a service account, install the proxy, and connect PostgreSQL locally. Learn the trade‑offs, verify the connection, and secure your database access with IAM.
Cloud SQL Auth Proxy Connection Pool Exhaustion: Diagnosing Intermittent Spikes
When Cloud SQL instances experience sudden spikes in connection count, the culprit is often the Auth Proxy’s connection‑pool behavior. Version 2.0.0 introduces a --max_connections flag that caps concurrent connections, but omitting it lets the proxy open a new connection per request. Coupled with a hard‑coded 60‑second idle timeout, this can leave orphaned s
Cloud Run and Cloud SQL Integration: Is the Auth Proxy a Connection Bottleneck?
Goal The goal is to quantify the potential connection bottleneck when a Cloud Run service talks to Cloud SQL through the Cloud SQL Auth proxy. Each incoming request typically opens a new TCP connection to the database, and Cloud Run’s default maximum concurrency is 80. If each request opens a distinct connection, the Cloud SQL instance may quickly hit its pe
cloudrunCloud SQL Auth Proxy and Cloud Run Application Connection Pools: Which Limit Governs Exhaustion Behavior?
Interoperability Boundary A Cloud Run service uses an application-level connection pool (for example, HikariCP with maxPoolSize=20 ) while the Cloud SQL Auth Proxy sidecar runs with --max_connections=10 . Both components enforce a connection ceiling, but the documented interaction between the two limits is not explicit about which one effectively governs bac
