Serverless Bookstore: Getting Started with AWS Lambda Functions

Overview

Welcome to this comprehensive guide on building serverless applications with AWS. Modern cloud architecture allows developers to create scalable applications without managing traditional server infrastructure. AWS provides a robust ecosystem of serverless technologies, including:

  • AWS Lambda for executing code
  • Amazon DynamoDB for data persistence
  • Amazon API Gateway for handling API requests
  • Amazon S3 and AWS Amplify for static web hosting

Here’s how these components work together in a typical serverless web application:
