AWS Fault Injection Service (FIS) launches new test scenarios for partial failures
News
This article announces two new test scenarios for AWS Fault Injection Service (FIS) designed to help applications handle partial disruptions and gray failures across Availability Zones.
- "AZ: Application Slowdown" tests latency and degraded performance within single AZs
- "Cross-AZ: Traffic Slowdown" tests multi-AZ applications handling traffic disruptions between AZs
- Both scenarios allow targeting specific application traffic portions for realistic testing
- Helps validate observability setups, tune alarm thresholds, and practice operational decisions
- New scenarios available in all AWS Regions where FIS is available, including GovCloud
These new FIS scenarios enable proactive testing of partial failures and gray failures, which are more common and harder to detect than complete outages.
