Question

A company needs to implement a workflow to process transactions. Each transaction goes through multiple levels of validation. Each validation level depends on the preceding validation level. The workflow must either process or reject each transaction within 24-hours. The workflow must run for less than 24 hours total. Which solution will meet these requirements with the LEAST operational cost?

Accepted Answer

Correct answer: A. The correct answer is A. Option A: Create a standard workflow in AWS Step Functions. Implement a Wait for Callback pattern to wait for the validation steps to finish. AWS Step Functions coordinates multi-step workflows as a managed state machine.
