AWS Lambda is a compute service that runs your code in response to events and automatically manages the compute resources for you. Together with Amazon Cognito, Amazon SNS push notifications, and Amazon DynamoDB, AWS Lambda is a powerful tool to build a highly scalable back end for your mobile or IoT applications. This session will take a practical approach to developing real-world IoT and mobile applications with AWS in which the back end is serverless and can scale virtually unlimited users without any infrastructure or servers to manage. This session is for those who want to get started quickly. It includes a review of key concepts and how the AWS SDKs make it easy to create powerful applications for an always-on world that connects beyond the desktop.
