Amazon Web Services (AWS) Lambda is a compute service that executes arbitrary Python code in response to developer-defined AWS events, such as inbound API calls or file uploads to AWS' Simple Storage Service (S3).
Lambda is often used as a "serverless" compute architecture, which allows developers to upload their Python code instead of spinning and configuring servers, deploying their code and scaling based on traffic.
