{"_comment":"Skeleton AWS FIS experiment template for an AZ power-interruption-style test, with a CloudWatch alarm stop condition and tag-scoped targets. This is a STARTING POINT illustrating the safety wiring (stopConditions + tag targeting), not a drop-in template. Prefer the managed 'AZ Availability: Power Interruption' scenario from the FIS Scenario Library for the full multi-service symptom set. Replace ACCOUNT, REGION, ROLE, ALARM, and tag values. Run in a NON-PROD account first.","description":"AZ impairment rehearsal - stop EC2 in one AZ, scoped by tag, halted on SLO breach","roleArn":"arn:aws:iam::ACCOUNT:role/fis-experiment-role","stopConditions":[{"source":"aws:cloudwatch:alarm","value":"arn:aws:cloudwatch:REGION:ACCOUNT:alarm:steady-state-slo-breach"}],"targets":{"ChaosEligibleInstances":{"resourceType":"aws:ec2:instance","selectionMode":"ALL","resourceTags":{"chaos-eligible":"true","az-impact-group":"az-a"},"filters":[{"path":"State.Name","values":["running"]},{"path":"Placement.AvailabilityZone","values":["REGION-a"]}]}},"actions":{"StopInstancesInAZ":{"actionId":"aws:ec2:stop-instances","description":"Simulate compute loss in one AZ; multi-AZ design should ride through","parameters":{"startInstancesAfterDuration":"PT30M"},"targets":{"Instances":"ChaosEligibleInstances"}}},"tags":{"Name":"az-power-interruption-rehearsal","environment":"non-prod"}}
