Explore the integration of serverless technology and IoT in this 49-minute conference talk from GOTO Chicago 2019. Learn how to build an application using an IoT button with a serverless backend powered by AWS Lambda. Follow along as the speaker unboxes the button, configures it for AWS IoT, and sets up the necessary security measures. Discover how to create an application that allows real-time session rating using the button's multiple click options. Gain insights into the potential of combining serverless backends with IoT flexibility, and participate in a live vote at the end of the session. The talk covers topics such as IoT services, AWS architecture, Cloud Formation, coding demonstrations, and practical implementations like creating feedback stacks and web clients.
