Jason Butz Chaos Engineering with FIS and Lambda Functions
AWS Community Day Midwest 2025 Jason Butz Chaos Engineering with FIS and Lambda Functions Imagine intentionally breaking your AWS Lambda functions to make them better. With the recent integration of AWS Fault Injection Service (FIS) and Lambda, you can now simulate real-world failures to test your system’s resilience and identify potential weaknesses. Dive into the world of chaos engineering and discover how FIS can help you build more robust and reliable serverless applications. This talk will introduce chaos engineering and AWS FIS, explain what capabilities FIS supports with Lambda, explain how the integration works, provide examples of how you can use FIS to test your serverless application, and show how to set up an FIS experiment with a Lambda function.
