Google Cloud Composer is a fully managed workflow orchestration service that is scalable and built on the open-source platform, Apache Airflow . It provides comprehensive integration with Google Cloud products, making it a suitable option for users already utilizing Google's platform or those seeking a hybrid/multi-cloud tool to manage their workflows. Cloud Composer's key feature is its robust integration with Google Cloud Platform , yet it also supports hybrid functionality. This allows for the orchestration of workflows across different cloud providers or on-premise servers. Built on Apache Airflow, Cloud Composer's core functionality is open-source, providing users with freedom from lock-in and ensuring portability. The service includes built-in integration for several Google Cloud services, including BigQuery, Dataflow, Dataproc, Datastore, Cloud Storage, Pub/Sub, AI Platform, and more. Additionally, Apache Airflow and, by extension, Cloud Composer, enable the representation of Directed Acyclic Graphs (DAGs) as Python code. Being fully managed, Cloud Composer allows users to concentrate on authoring, scheduling, and monitoring their workflows, rather than provisioning resources.
