AWS AppSync Documentation

Organizations choose to build APIs with GraphQL because it helps them develop applications faster, by giving front-end developers the ability to query multiple databases, microservices, and APIs with a single GraphQL endpoint.
 
AWS AppSync is a fully managed service that helps develop GraphQL APIs by handling the heavy lifting of securely connecting to data sources like AWS DynamoDB, Lambda, and more. AWS AppSync also helps add caches to improve performance, subscriptions to support real-time updates, and client-side data stores that keep off-line clients in sync. Once deployed, AWS AppSync scales your GraphQL API execution engine up and down to meet API request volumes.
