Serverless Architecture
This document discusses serverless architecture and frameworks. It describes backend as a service (BaaS) and function as a service (FaaS), with examples like Amazon Lambda, Google Cloud Functions, and Azure Functions. Frameworks for serverless apps are presented, including Apex, Serverless, Zappa, and Sparta. The document also covers security, testing, example architectures, and resources for serverless development.
