Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 351 discussion

This is why I’m voting D…..QUESTION ASKED FOR IT TO: use serverless concepts while performing the different aspects of the workflow. Is option D utilizing Serverless concepts?

It is D. Cannot be C because C is "scheduled"

While considering this requirement: The architecture needs to be more distributed and to use serverless concepts while performing the different aspects of the workflow And checking the following link : https://aws.amazon.com/step-functions/?nc1=h_ls, Answer D is the best for this use case

One of the use cases for step functions is to Automate extract, transform, and load (ETL) processes. https://aws.amazon.com/step-functions/#:~:text=for%20modern%20applications.-,Use%20cases,-Automate%20extract%2C%20transform

Step Functions is based on state machines and tasks. A state machine is a workflow. A task is a state in a workflow that represents a single unit of work that another AWS service performs. Each step in a workflow is a state. Depending on your use case, you can have Step Functions call AWS services, such as Lambda, to perform tasks. https://docs.aws.amazon.com/step-functions/latest/dg/welcome.html

There are two main types of routers used in event-driven architectures: event buses and event topics. At AWS, we offer Amazon EventBridge to build event buses and Amazon Simple Notification Service (SNS) to build event topics. https://aws.amazon.com/event-driven-architecture/

Step 3: Create a State Machine Use the Step Functions console to create a state machine that invokes the Lambda function that you created earlier in Step 1. https://docs.aws.amazon.com/step-functions/latest/dg/tutorial-creating-lambda-state-machine.html In Step Functions, a workflow is called a state machine, which is a series of event-driven steps. Each step in a workflow is called a state.

Vou de C, orientada a eventos

AWS Step functions is serverless Visual workflows for distributed applications https://aws.amazon.com/step-functions/

Could it be a C because it's event-driven architecture?

Option D.. AWS Step functions are used for distributed applications
