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.
