AWS FIS Adds Partial-Failure Test Scenarios for AZs

🧪 AWS Fault Injection Service (FIS) introduces two new pre-built experiment scenarios to simulate partial, cross- and single-AZ disruptions. The AZ: Application Slowdown scenario simulates increased latency and degraded performance within a single Availability Zone to validate observability, alarms, and AZ evacuation playbooks. The Cross-AZ: Traffic Slowdown scenario simulates degraded traffic between AZs and lets you target subsets of traffic for realistic gray-failure testing. These scenarios are available in all Regions where AWS FIS is offered, including AWS GovCloud (US).

AWS FIS Adds EBS I/O Latency Injection for Testing

⚙️ Amazon EBS now provides a latency injection action in AWS Fault Injection Service (FIS) to simulate degraded I/O performance on EBS volumes as part of controlled fault injection experiments. The action reproduces real-world signals such as Amazon CloudWatch alarms and OS timeouts so teams can observe application behavior and validate recovery. Pre-defined templates are available in the EBS and FIS consoles, and experiments can be customized or combined with other actions to integrate into chaos engineering and CI workflows. The capability is available in all Regions where FIS is supported.
