DEA-C01Domain 3: Data Operations and SupportData OperationsmediumSingle choice

A team has interdependent ETL jobs — job B only after job A succeeds, with retries and alerting — and wants managed Apache Airflow. Which service runs Airflow on AWS without self-managing?

A.AWS Step Functions

Step Functions orchestrates serverless workflows but isn't Airflow — teams with existing DAGs would need to rewrite.

B.Amazon MWAA

Correct. MWAA runs your Airflow DAGs in a managed environment.

C.Amazon EventBridge Scheduler

EventBridge Scheduler triggers single targets on a schedule — it doesn't model multi-step dependencies.

D.AWS Batch

Batch runs containerized jobs on compute it provisions — not a DAG orchestrator.

Why this answer

Amazon MWAA is managed Apache Airflow — DAGs, scheduling, retries, and dependency management without running Airflow infrastructure. Step Functions can orchestrate too, but the question asks for managed Airflow specifically.
