AWS AppSync Use Cases

Let’s explore some common use cases for AWS AppSync, where AWS AppSync can help to build GraphQL APIs fast. Simple Data-Centric GraphQL API A typical use-case for AppSync is providing a data-centric API to an existing data source. The advantage

Building GraphQL APIs with AWS AppSync

GraphQL is great but requires the manual installation and maintenance of software infrastructure components, tedious configuration, and some manual tweaking. And when running a productive GraphQL system, you need to find a way to scale the system up and down

Find your way in AppSync – AWS AppSync Architecture

Find your way in AppSync – AWS AppSync Architecture

AWS AppSync is a fully-managed serverless GraphQL infrastructure. Because it runs on a serverless, managed infrastructure, it scales automatically and does not require any manual installation nor any maintenance. Thus, AppSync allows us to get started quickly without any impediments.

What is a GraphQL Pattern?

GraphQL queries consist of one or more patterns which are matched against the big graph containing all the data on the server. The patterns describe a subgraph of the big graph and is used to search for the relevant data in the

AppSync Architecture

Let’s have a look at the AppSync architecture. In the figure below we have depicted such a high-level solution architecture for an app, an AppSync API and AWS data sources. On the left-hand side we have the clients connecting to
