Scenarios define events or conditions that you can apply to test the resilience of your applications, such as an AZ power interruption or cross-region connectivity interruption. Scenarios are created and owned by AWS, and minimize undifferentiated heavy lifting by providing you with pre-defined targets and fault actions (e.g., gradually increase CPU load from 90% to 100% for Amazon EC2instances) for possible application impairments. Scenarios are provided through the Scenario Library in the FIS console, and are run using an FIS experiment template. In order to run an experiment using a scenario, simply select the scenario from the library, copy it to your experiment template, and specify your application details. Each scenario includes a detailed description and suggested metrics to measure the response of your application during the experiment, helping you improve the resilience posture of your applications over time.
