A data engineer wants to orchestrate a set of extract, transform, and load (ETL) jobs that run on AWS. The ETL jobs contain tasks that must run…

Amazon Managed Workflows for Apache Airflow (Amazon MWAA) is the most suitable service. Apache Airflow is an open-source platform designed to programmatically author, schedule, and monitor workflows. A key feature is that workflows, known as Directed Acyclic Graphs (DAGs), are defined as Python code. This directly fulfills the requirement to use Python for orchestration. Airflow provides a rich library of operators to interact with various AWS services, including Amazon EMR and Amazon Redshift, and can easily make API calls. Its core functionality includes robust scheduling, dependency management, and automatic handling of task failures and retries.

and load (ETL) activities that are composed of multiple jobs

crawlers

and triggers. Each of these workflows can be thought of as a directed acyclic graph (DAG)." (Note: This describes a GUI/API-defined DAG

not a Python-scripted one like Airflow).
