Explore the intersection of serverless computing and Internet of Things (IoT) in this conference talk from GOTO Amsterdam 2019. Dive into building an application that utilizes a simple IoT button with a serverless backend powered by AWS Lambda. Learn how to unbox and configure an IoT button for use with AWS IoT, set up required security measures, and create an application allowing session rating through multiple click options. Gain insights into serverless backends' flexibility and potential applications. Follow along as the speaker demonstrates the process, from introducing SAM (Serverless Application Model) and AWS CloudFormation to coding and testing. By the end, acquire a solid understanding of integrating IoT devices with serverless architectures and their practical implementations.
