AWS AppSync
#238 · Level 3 · Modern architecture · Web, mobile and business appsConcept
Section titled “Concept”AWS AppSync is a managed GraphQL API service. GraphQL is an API method where the app itself says exactly which data it needs. AppSync has a schema, and resolvers send each request to data sources such as DynamoDB, Lambda, OpenSearch or an HTTP API. With subscriptions, connected apps get an update right away when data changes. AWS does the work of running servers, scaling and handling connections.
