Amazon Web Services
In this chapter, we will utilize Amazon Web Services (AWS) to create several serverless applications. We will use Lambda to create a Hello World function that is triggered by a test case that we’ll create. We will also use API Gateway resources and methods to trigger a Lambda function with RESTful HTTP requests that will return data from DynamoDB. Finally, we will explore a triggered storage application, where we are able to resize images uploaded to Amazon’s S3 service using a Lambda function. By the end of this chapter, we will have three serverless applications and experience with several AWS services.
