Test Azure Container Instances reliability with Gremlin Failure Flags. Inject latency and errors to validate graceful degradation without host access.
Azure Container Instances gives you a container with no orchestrator around it. No scheduler to reschedule it, no service mesh to route around it, no node pool to absorb a problem. Whatever resilience exists has to live inside the container or in whatever calls it.
That makes ACI a common home for utility workloads: batch tasks, integrations, glue between systems. Those workloads receive the least engineering attention and the least error handling, which is an uncomfortable pairing with the least platform protection.
Since there's no host to work with, testing happens in the code. Add Failure Flags to your container and you can inject latency and errors against a running instance. You'll learn whether it retries, whether it exits in a way that signals failure to whatever invoked it, and whether it can hang indefinitely.
For a container with nothing watching it, hanging silently is the worst available outcome, and it's the one most applications default to.
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.
* Failure Flags works wherever you can add the SDK to your application and run the Gremlin sidecar. Not every language and platform combination has been individually tested, and not all are officially supported. Check our compatibility documentation for what's verified, or get in touch if you don't see your runtime.
