Test how your application handles a Cloud SQL outage. Run Gremlin network experiments and reliability tests to validate timeouts and failover.
Most applications never connect to Cloud SQL directly. They go through the Auth Proxy or a connector library that handles IAM and encryption, and in the process, this becomes a component with its own failure modes. Teams think about the database and forget the layer sitting in front of it.
Testing the whole connection path answers questions that database metrics can't:
- Is this a database problem or a proxy problem? A proxy that can't refresh credentials produces symptoms that look like database failures. Knowing the difference shortens every incident.
- Does your connection pool survive a failover? Blackhole experiments make the endpoint unreachable so you can confirm the application automatically reconnects instead of holding a dead socket.
- Do your timeouts fire before your callers give up? Latency experiments slow the path so you can verify your callers timeout gracefully.
Telling the database apart from the proxy is the difference between a five-minute fix and an hour of guesswork while your customers wait.
Dependencies: Failure Test
Simulate a failed dependency by dropping all network traffic to the dependency.
Dependencies: Latency Test
Recreate poor network conditions by delaying all network traffic to a dependency by 100ms.
* Testing a dependency doesn't require installing anything on it. Gremlin runs the experiment from the service that calls it, so compatibility depends on that host rather than on the dependency itself. Check our compatibility documentation for supported operating systems and platforms, or get in touch if you don't see yours.
