Web Hosting and GraphQL APIs

Web Hosting

GraphQL allows developers to easily create complex data structures for APIs without writing custom code, significantly shortening development times while increasing data structure flexibility and providing seamless integration between front-end and back-end systems.

A GraphQL query’s schema is defined hierarchically and declaratively and includes object types and fields, each strongly typed, such that the query engine ensures every field and value in the schema is returned in query results. Furthermore, queries won’t return more data than needed unlike REST APIs that often return more than is requested.

This approach allows for efficient UI rendering and data transfer costs reduction, and also allows GraphQL servers to combine data from different sources – including relational databases and NoSQL stores.

A GraphQL server can support subscription requests to allow clients to establish long-term, bidirectional communication channels with it and access data real time. As opposed to queries or mutations that use short-lived HTTP connections, subscription requests are fulfilled through long-running WebSocket sessions that run continuously in the background.

If you need a managed GraphQL API layer for your application, consider AWS AppSync. It takes care in parsing and resolving requests as well as connecting to back-end services like Amazon DynamoDB, NoSQL databases or AWS Lambda functions; charges will apply separately depending on which services are used, in addition to infrastructure charges.
