Using AWS Step Functions and the AWS SDK for Java to build workflows that sends notifications over multiple channels
You can use Amazon Web Services to create a workflow that sends notifications over multiple channels. There are many practical business needs for this type of functionality. For example, a weather agency needs to warn many people about a storm, or a school wants to send parents alerts when kids are missing. The use case for this AWS tutorial assumes you work at a school and you need to alert parents when a student skips school. Do you send an email message, do you phone the parents, or do you send a text message to a mobile device? The AWS workflow created in this tutorial sends messages over multiple channels, including email, as shown in this illustration. In this AWS tutorial, you create an AWS serverless workflow by using the AWS SDK for Java and AWS Step Functions. Each workflow step is implemented by using an AWS Lambda function. Lambda is a compute service that enables you to run code without provisioning or managing servers. For more information about Lambda, see Wh...
