    Why switch from Google Cloud Composer (Managed Airflow)

    Managed Airflow from the project's main commercial backer, runnable on AWS, Azure or Google Cloud.

    Pros

    • Runs standard Airflow DAGs, so existing pipelines move over with little change
    • Workers scale to zero when idle
    • Private cloud option for regulated environments
    • Buyable through AWS, Azure and GCP marketplaces

    Cons

    • Deployments bill by the hour even when no tasks run
    • Only orchestrates Airflow, so it doesn't help if you prefer another framework
    • SSO enforcement and longer audit logs need the Business tier or higher
