AWS AppSync GraphQL
AWS AppSync lets you build production GraphQL APIs with zero backend code management. Covers GraphQL schema design, resolver mapping templates (VTL or JavaScript), authentication (API keys, Cognito, IAM, OIDC), subscriptions for real-time data, and caching strategies. Mastery means building $100k+ SaaS APIs with automatic scaling. Learning path: GraphQL basics (2 weeks) → AppSync fundamentals (3 weeks) → resolvers + data sources (2 weeks) → auth + permissions (1 week) → production patterns (2 weeks).
What is AWS AppSync GraphQL
AWS AppSync is a managed GraphQL service that sits between your client and backend data sources, Lambda, DynamoDB, RDS, Elasticsearch, HTTP endpoints. You define your GraphQL schema, write resolver mapping templates (VTL or JavaScript), and AppSync handles schema validation, field resolution, authentication, real-time subscriptions (via WebSocket), and automatic scaling. In 2026, AppSync is the default serverless GraphQL platform on AWS. No GraphQL server to deploy, no horizontal scaling headaches. You pay per request + data transfer, and you get built-in caching, authorization rules, and offline support via AWS Amplify.
