The document discusses using Python with AWS Lambda. It introduces serverless frameworks like AWS Lambda, Google Cloud Functions, and Microsoft Azure Functions. It then focuses on using Python with AWS Lambda, including how to package dependencies, deploy code, and leverage the Serverless framework to simplify deployments. Logging to CloudWatch Logs and adding unit tests are also covered.
