Today, AWS announces the expanded support of AWS Fault Injection Simulator (FIS) for Amazon EC2 with a new SSM document to the fill disk of EC2 instances. FIS is a fully managed service which allows you to run experiments to test how your applications behaves during an impairment, and helps you improve application performance, observability, and resilience. The new disk fill document consumes disk space to see how the application behaves when disk space is unavailable.
