Question 68 of 100 | ← Chapter 1

A company uses Amazon EMR as an extract, transform, and load (ETL) pipeline to transform data that comes from multiple sources. A data Engineer must orchestrate the pipeline to maximize performance. Which AWS service will meet this requirement MOST cost effectively?

• A. Amazon EventBridge
• B. Amazon Managed Workflows for Apache Airflow (Amazon MWAA)
• C. AWS Step Functions ✓
• D. AWS Glue Workflows

Correct Answer: C. AWS Step Functions

Explanation

AWSStepFunctions是一种用于协调和编排多步骤工作流的服务。对于需要最大化ETL管道性能的情况，它能够提供可视化的工作流设计、可靠的执行和错误处理机制，并且在成本效益方面表现出色。相比之下，AmazonEventBridge主要用于事件驱动的架构，AmazonMWAA是针对ApacheAirflow的托管服务，AWSGlueWorkflows更侧重于数据集成和转换任务的编排。综合考虑，AWSStepFunctions最能满足需求且具有较高的成本效益，所以答案选C。
