SAA-C03 Q671 · Serverless

Question

A company is moving its data management application to AWS. The company wants to transition to an event-driven architecture. The architecture needs to be more distributed and to use serverless concepts while performing the different aspects of the workflow. The company also wants to minimize operational overhead. Which solution will meet these requirements?

Accepted Answer

This answer satisfies every requirement stated in the question:

1. **Event-driven architecture**: AWS Step Functions is a workflow orchestration service that reacts to events and transitions between states based on outputs/conditions — a core event-driven pattern.

2. **Distributed workflow**: Step Functions' **state machine** model breaks the workflow into discrete, independent steps. Each step can be a separate Lambda function, making the architecture inherently distributed.

3. **Serverless concepts**: Both Step Functions and Lambda are fully serverless. There are no servers to provision, patch, or manage. You pay only for what you use (per state transition for Step Functions, per invocation/duration for Lambda).

4. **Minimize operational overhead**: Step Functions provides built-in e
