AWS AppSync is a fully-managed, pay-per-use GraphQL service that enables developers to prototype and build web and mobile applications using real-time data. With AppSync, developers can create an API that is accessible under a single endpoint and utilizes GraphQL as a unified query language. AppSync handles the data requests and responses, as well as connections to one or more data sources like AWS Lambda, AWS DynamoDB, and HTTP APIs.

In this lab, you will work with the AWS AppSync interface via the AWS console to build a GraphQL API backed by multiple data sources. You will learn how to manage data models, schemas, resolvers, and more via the AWS AppSync console.

Note: GraphQL concepts and terminology are used throughout this lab. Students who are unfamiliar with GraphQL, or who need a refresher, are highly encouraged to perform the Introduction to GraphQL hands-on lab.
