Test how your application handles a Cloud Storage outage. Run Gremlin network experiments and reliability tests to validate timeouts and fallbacks.
Google Cloud Storage offers strong consistency, which removes a class of bug teams used to design around and encourages treating the service as always correct. Correctness and availability are different guarantees, and applications built on the first assumption tend to ignore the second.
Fan-out workloads make that expensive. A job iterating over thousands of objects with no timeout on individual reads can stall on one and hold everything behind it. Resumable uploads add a second problem: an interrupted upload leaves state that has to be resumed or abandoned deliberately, and code that skips that path leaves partial objects and orphaned sessions behind.
Gremlin shows you whether your bulk operations have bounded behavior. Latency experiments slow the storage endpoint so you can find the operations with no upper limit on how long they will wait. Blackhole experiments remove it entirely, which tells you whether your application degrades or hangs.
Bulk operations tend to be written for the day storage answers quickly. Testing tells you what happens on the day it doesn't.
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.
Unreliable Networks - Dependencies
Simulate unreliable network conditions when communicating with dependencies by adding latency to API calls. Test whether your users are affected when dependency response times degrade.
* 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.
