Amazon S3 Express One Zone now supports resilience testing with AWS Fault Injection Service

Amazon S3 Express One Zone, a high-performance S3 storage class for latency-sensitive applications, now supports resilience testing with AWS Fault Injection Service (FIS). With this launch, you can use the FIS network disruption action to test the failover response and recovery of your latency-sensitive applications in the unlikely event of a disruption to an Availability Zone (AZ) that impairs access to your data. You can use the results of FIS experiments to verify your monitoring, test recovery processes, and improve application resilience.

With FIS, you can disrupt connectivity to your S3 Express One Zone data in S3 directory buckets, helping you validate application resilience. During the FIS experiment, data plane requests made to directory buckets will timeout. This fault action is also included in the FIS AZ Availability: Power Interruption scenario, so you can test the resilience of your applications when an AZ event impacts multiple AWS services.

You can use the updated FIS network disruption action for S3 Express One Zone data in all AWS Regions where the storage class is available. To get started with testing the resilience of applications that store data in S3 Express One Zone, you can use the AWS Management Console, AWS CLI, or FIS API.
