Creating a data workflow using AWS Step Functions

AWS Step Functions is a serverless workflow orchestration service that enables you to connect and manage various AWS services within a streamlined workflow. This allows for the rapid development and updating of applications.

Step Functions employs a state machine approach, where each step in the workflow is represented by a state. These states are defined using the Amazon States Language, a JSON-based format. By chaining together different states, you can create complex workflows that integrate services such as AWS Lambda, AWS Fargate, and Amazon SageMaker to build powerful applications.

In this recipe, we’ll create a simple AWS Step Functions workflow that uses two AWS Lambda functions: one that gets data and one that processes data.

How to do it…

1. Create two Lambda functions:
   1. Go to the AWS Management Console.
   2. Navigate to Lambda by searching for Lambda in the services search bar.
   3. Create a new Lambda function...
