You need a managed, daily orchestration solution for a multi-step pipeline that runs Dataproc and Dataflow jobs with dependencies. Which tool do you choose?

Cloud Composer is the best choice because it's a fully managed Apache Airflow service, ideal for orchestrating complex, multi-step pipelines involving various Google Cloud services like Dataproc and Dataflow, with robust dependency management and scheduling capabilities. Cron is a basic Linux utility for time-based scheduling and lacks the advanced orchestration features, dependency management, and monitoring needed for complex pipelines. Cloud Scheduler is a fully managed cron job service but is limited to simple HTTP calls or Pub/Sub messages and doesn't offer the rich orchestration features of Airflow. Workflow Templates on Dataproc are specific to Dataproc jobs and cannot orchestrate Dataflow or other services.
