A data engineer is designing a hybrid data orchestration workflow that uses both on-premises and cloud resources and wants to prioritize portability and open-source tools. Which service should be used in both environments?

Amazon Managed Workflows for Apache Airflow (Amazon MWAA) is the correct choice because Apache Airflow is an open-source workflow management platform widely used for orchestrating complex data pipelines. Its open-source nature ensures portability, allowing the same workflows to run on-premises and in the cloud (via MWAA). This aligns perfectly with the requirement for both portability and open-source tools in a hybrid environment. AWS Data Exchange is a data marketplace, not a workflow orchestration service. Amazon Simple Workflow Service (SWF) is a fully managed workflow service but is not open-source and lacks the broad community support and portability of Airflow. AWS Glue is an extract, transform, and load (ETL) service, not a general-purpose workflow orchestrator for hybrid environments.
