What Is Appsync

Power your applications with the right data, from one or more data sources, at global scale

AWS AppSync simplifies application development by letting you create a flexible API to securely access, manipulate, and combine data from one or more data sources. AppSync is a managed service that uses GraphQL to make it easy for applications to get exactly the data they need.

With AppSync, you can build scalable applications, including those requiring real-time updates, on a range of data sources such as NoSQL data stores, relational databases, HTTP APIs, and your custom data sources with AWS Lambda. For mobile and web apps, AppSync additionally provides local data access when devices go offline, and data synchronization with customizable conflict resolution, when they are back online.

Get started in minutes with the intuitive AWS AppSync management console, or use AWS Amplify CLI to automatically generate your API and client-side code. AWS AppSync integrates with Amazon DynamoDB, Amazon Elasticsearch, and Amazon Lambda, enabling you to create sophisticated applications, with virtually unlimited throughput and storage, that scale according to your business needs.

Real-time subscriptions and offline access

AWS AppSync enables real-time subscriptions across millions of devices, as well as offline access to app data. When an offline device reconnects, AWS AppSync syncs only the updates that occurred when the device was disconnected, and not the entire database. AWS AppSync offers user-customizable server-side conflict resolution that does the heavy lifting of managing data conflicts so you don’t have to.

Unify and secure access to your distributed data

Perform complex queries and aggregation across your on-premise or cloud data sources using GraphQL. AWS AppSync makes it easy to secure your app data using powerful fine-grained access controls.

Use cases

Real Time Collaboration

Data Broadcasting

You can use AWS AppSync to enable scalable, real-time collaboration use cases by broadcasting data from the backend to all connected clients (one-to-many) or broadcasting data between clients themselves (many-to-many). For example, you can build a second screen scenario where you broadcast the same data to all clients, and users then respond in real time by voting and commenting about what's on the screen.

Reference Architecture: Sample Code

Chat Applications

You can use AWS AppSync to power collaborative and conversational applications. For example, you can build a mobile and web application that supports multiple private chat rooms, offers access to conversation history, and enqueues outbound messages, even when the device is offline.

Reference Architecture: Sample Code

Internet of Things

You can use AWS AppSync to access IoT device data sent to AWS IoT. For instance, you can build a real-time dashboard in a mobile or web application to visualize telemetry from a connected car.

Data Layer

Polyglot Backend Data Access

What Is Appsync Aws

You can retrieve or modify data from multiple data sources (SQL databases in Amazon Aurora Serverless, NoSQL tables in Amazon DynamoDB, search data in Amazon Elasticsearch Service, REST endpoints in Amazon API Gateway, or serverless backends in AWS Lambda) with a single call. Query and create relations between data sources using GraphQL connections. Provide real-time and offline capabilities to web and mobile clients.

Microservices Access Layer

You can use AWS AppSync as a single interface to access and combine data from multiple microservices in your application, even if they're running in different environments such as containers in a VPC, behind a REST API on Amazon API Gateway, or behind a GraphQL API on another AWS AppSync endpoint.

Offline

Offline Delta Sync

You can use AWS AppSync to provide a seamless experience to mobile and web users when devices go offline, as well as automatically reconnect and sync data when the device comes back online. With delta sync, AppSync syncs only the modified data, instead of the whole data set.
