A managed service for building APIs that let clients request exactly the data they need in a single query, rather than making multiple requests to different endpoints. Like ordering from a custom menu where you pick exactly what you want, instead of choosing from fixed meal combos.
A mobile app team uses AWS AppSync to build a GraphQL API that lets their iOS and Android apps fetch user profiles, posts, and comments in a single query — reducing network calls by 80% compared to their old REST API and dramatically improving load times on slow connections.
AWS AppSync is a fully managed GraphQL API service with built-in real-time subscriptions and offline/client sync integrations. Azure and GCP commonly provide GraphQL via API management gateways (Azure API Management, Apigee) in front of your own GraphQL server/resolvers running on compute (Functions/Container Apps/Cloud Run). OCI does not have a widely recognized first-party managed GraphQL service equivalent; GraphQL is typically self-hosted on OCI compute (e.g., OKE/Compute) and optionally fronted by OCI API Gateway.
