Amazon API Gateway is a fully managed service that makes it easy for developers to create, deploy, secure, and monitor APIs at any scale. In this presentation, you’ll find out how to quickly declare an API interface and connect it with code running on AWS Lambda. Amazon API Gateway handles all of the tasks involved in accepting and processing up to hundreds of thousands of concurrent API calls, including traffic management, authorization and access control, monitoring, and API version management. We will demonstrate how to build an API that uses AWS Identity and Access Management (IAM) for authorization and Amazon Cognito to retrieve temporary credentials for your API calls. We will write the AWS Lambda function code in Java and build an iOS sample application in Objective C.
