AWS Fault Injection Simulator is a fully managed fault injection service that makes it easier for teams to discover an application’s weaknesses at scale in order to improve performance, observability, and resiliency.
Fault Injection Simulator 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.
With Fault Injection Simulator, teams can quickly set up experiments using pre-built templates that generate the desired disruptions. Fault Injection Simulator 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.
With a few clicks in the console, teams can run complex scenarios with common distributed system failures happening in parallel or building sequentially over time, enabling them to create the real world conditions necessary to find hidden weaknesses.
