This document provides an overview of AWS Lambda, including its history, supported languages, use cases, performance, pricing, and alternatives. AWS Lambda allows writing code that runs in response to events and automatically manages the computing resources required to run the code. It is useful for tasks like log processing, event stream processing, deployment automation, infrastructure automation, and serverless APIs. The document also includes a demo of using AWS Lambda for infrastructure automation with Route53.
