AWS Fault Injection Simulator

Improve resiliency and performance with controlled experiments  

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.

Use prebuilt templates to set up and run high-quality experiments in minutes.

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

How it works

AWS Fault Injection Simulator (FIS) is a fully managed service for running fault injection experiments to improve an application’s performance, observability, and resiliency. 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

Run a game-day simulation

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

Integrate with your delivery pipeline

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

Run CPU stress on an instance

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