AWS AppSync Events is a fully managed service that allows developers to create secure and performant WebSocket APIs. Starting today, developers can use their AppSync Events APIs to publish events directly over WebSocket connections, complementing the existing HTTP API publishing capability. This enhancement enables applications to both publish and subscribe to events using a single WebSocket connection, streamlining the implementation of real-time features. The new WebSocket publishing capability simplifies the development of collaborative applications such as chat systems, multiplayer games, and shared document editing. Developers can now maintain a single connection for bi-directional communication, reducing complexity and improving performance by eliminating the need to manage separate connections for publishing and subscribing to events. This approach helps reduce latency in real-time interactive applications by removing the overhead of establishing new HTTP connections for each event publication. This feature is now available in all AWS Regions where AWS AppSync is supported. To get started, developers can use their favorite WebSocket client. For more information, view our new https://aws.amazon.com/blogs/mobile/building-real-time-apps-with-aws-appsync-events-websocket-publishing/ and visit the AWS AppSync https://docs.aws.amazon.com/appsync/latest/eventapi/publish-websocket.html for detailed implementation examples and best practices.

AWS AppSync is a fully managed API management service that connects applications to events, data, and AI models. AppSync now supports sharing GraphQL APIs across AWS accounts using AWS Resource Access Manager (RAM). This new feature allows customers to securely share their AppSync GraphQL APIs configured with IAM authorization, including private APIs, with other AWS accounts within their organization or with third parties. Before today, customers had to set up additional networking infrastructure to share their private GraphQL APIs between their organization accounts. With this enhancement, customers can now centralize their GraphQL API management in a dedicated account and share access to these APIs with other accounts. For example, a central API team can create and manage private GraphQL APIs, then share them with different application or networking teams in different accounts. This approach simplifies API governance, improves security, and enables more flexible and scalable architectures for multi-account environments. Customers can optionally enable CloudTrail to capture API activities related to AWS AppSync GraphQL APIs as events for additional security and visibility. This feature is now available in all AWS Regions where AWS AppSync is available. To get started, refer to the https://docs.aws.amazon.com/appsync/latest/devguide/sharing-graphql-apis.html, and visit the AWS RAM console to start sharing your APIs. For more information about sharing resources with AWS RAM, see the https://docs.aws.amazon.com/ram/latest/userguide/what-is.html.
