Benefits

Find performance bottlenecks or other unknown weaknesses missed by traditional software tests.

Define specific conditions to stop an experiment or roll back to the pre-experiment state.

Run experiments in minutes using pre-built scenarios from the FIS Scenario Library.

Get superior insights by generating real-world failure conditions, such as impaired performance of different resources.

How it works

Part of AWS Resilience Hub, AWS Fault Injection Service (FIS) is a fully managed service for running fault injection experiments to improve an application’s performance, observability, and resilience. FIS simplifies the process of setting up and running controlled fault injection experiments across a range of AWS services, so teams can build confidence in their application behavior.

Why FIS?

FIS provides the controls and guardrails that teams need to run experiments in production, such as automatically rolling back or stopping the experiment if specific conditions are met.

Use cases

Simulate previous failures, known process or team weaknesses, or seasonal spikes in demand, and monitor the performance of your system.

Repeatedly test the impact of fault actions, such as injecting task-level container failures, as part of your software delivery process.

Test how your applications handle CPU stress and if CPU utilization exceeds your specified threshold.
