Real-Time Messaging with Serverless Web Applications

Broadcast Date: June 9, 2020

In this session - the second in a five part series - you will communicate with your front-end application using WebSockets. The theme park application uses this mechanism to publish ride wait times back to the client application. We will use AWS IoT Core and Amazon SNS to build a publish-subscribe topic to broadcast wait times to app users. Expect to leave with a solid understanding of IoT and MQTT functionality as it applies to Innovator Island, as well as how to pass messages between front and back end. In the next session, we’ll build on this and set up photo processing functionality.

In this episode, we'll talk about:

• How IoT Core and MQTT works in this application
• Passing messages between the backend and front-end
• How Cognito works in this implementation

Who should attend?

Front-end and Backend Developers, IT Professionals, Systems Architects
