(Part 1)<\/a>, we have discussed AWS Step functions, its features, benefits, use cases, etc. In this blog, we will discuss a business scenario to configure and create a serverless workflow to handle the issue resolution statuses raised by each of the customers and follow a systematic process for the same.<\/p>\n\n\n\n<h2><strong>Business Scenario:<\/strong><\/h2>\n\n\n\n<p class=\"has-text-align-justify\">Let\u2019s say a company has a department of customer service that handles all the service requests raised by the customers. It\u2019s getting difficult to handle the record of each issue raised by each of the customers. You are a developer at the same company and you have been addressed about this issue to be resolved as soon as possible. A senior in your team asks you to create a serverless application to automate the handling of the issue statuses raised by the customers. While you could have one Lambda function call the other, you worry that managing all of those connections will become challenging as the application becomes more sophisticated. Apart from this, if there are some same changes required in the application flow in multiple places, you could end up writing the same code over and over again.&nbsp;<\/p>\n\n\n\n<p class=\"has-text-align-justify\">So, to solve this issue, you decide to use AWS Step Functions.&nbsp;<\/p>\n\n\n\n<p>To implement this, we will do the following:<\/p>\n\n\n\n<ul><li>Sign in to your AWS console and navigate to the Step Function dashboard.<\/li><li>Create a new Step function state machine.<\/li><li>Create a JSON-formatted workflow execution for the step function.<\/li><li>Navigate to the IAM console and attach a policy to the created IAM Step Function role to perform the execution of the Lambda functions.<\/li><li>Navigate to the AWS Lambda console.<\/li><li>Create 5 Lambda functions for the different types of states with the specific codes in them.<\/li><li>Navigate back to the Step Function console, edit the state machine, and attach each Lambda function ARN to the respective states in the JSON-formatted Step Function code.<\/li><li>Save the state machine code and create a new execution.<\/li><li>Check the workflow in the Graph inspector on the AWS Step Function dashboard.<\/li><li>Check the execution details.<\/li><li>Create multiple executions to see the different types of execution and follow the same steps as above to check the execution.<\/li><\/ul>\n\n\n\n<p class=\"has-text-align-justify\">Sign in to your AWS account and navigate to the <a href=\"https:\/\/aws.amazon.com\/step-functions\/\" target=\"_blank\" rel=\"noreferrer noopener\">AWS Step Functions<\/a> dashboard.
