Test Azure Web App for Containers reliability with Gremlin Failure Flags. Inject latency and errors to validate dependency failure handling.
Running a container on Azure App Service is often a migration destination: an application that used to run somewhere with more control, now packaged and deployed onto a managed platform. The packaging changed. The application's assumptions about its environment usually didn't.
Those assumptions matter. Code written for a long-lived VM may hold connections, cache aggressively in memory, or assume it will be restarted rarely. On a platform that recycles instances on its own schedule, those behaviors interact with dependency failures in ways nobody designed for.
Add Failure Flags to your containerized application and inject latency or errors into a specific dependency. You'll find out whether the migration preserved the resilience the application had before, or whether it only preserved the functionality.
Teams verify that a migrated application works, which is necessary. Functional parity and failure parity are different things, and only one of them usually gets checked.
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.
