Summary

In this chapter, you learned about AWS SAM, an open source framework that simplifies the development, testing, and deployment of serverless applications on AWS. SAM uses AWS CloudFormation to help build underlying infrastructure that supports your serverless application. It provides a syntax for expressing functions, APIs, and databases, allowing you to define and manage your IaC.

You also discovered the integration of AWS AppSync with Amazon DynamoDB, showcasing the powerful combination these services offer for building scalable, serverless, and real-time applications. By defining the GraphQL schema in AWS AppSync and configuring resolvers that map GraphQL operations directly to data operations in DynamoDB, you learned about the seamless interaction for efficient data synchronization and management without the need for intermediate layers, making it a highly effective solution for developing modern applications.

With AppSync, you can run queries and mutations to interact...
