This document discusses building a serverless GraphQL API using AWS API Gateway and AWS Lambda. It proposes hosting a GraphQL endpoint behind API Gateway that can distribute GraphQL queries to multiple Lambda functions acting as resolvers. This serverless architecture allows building declarative, introspective GraphQL APIs without multiple round trips to the server.
