Serverless Chaos Demo – Last video • We talked about blast radius and how to start with the smallest possible experiment. • Added per function injection control to Adrian Hornsby’s Latency Injection layer using parameter store and environment variables. • Made it easier to deploy the Latency Injection layer using Serverless Framework. • Performed a demo on the serverless application.

What has Adrian been up to?

What has Adrian been up to? • Merged our changes from the last video to his Lambda layer (Yay!). • Added HTTP Error status code injection using error_code. • Added exception injection using exception_msg. • Added functionality to control the rate of failure. • Renamed the layer to Failure Injection Layer.
