Cloud Composer

• Cloud Composer is a fully managed workflow orchestration service, built on Apache Airflow, enabling workflow creation that spans across clouds and on-premises data centers.
• Cloud Composer requires no installation or has no management overhead.
• Cloud Composer integrates with Cloud Logging and Cloud Monitoring to provide a central place to view all Airflow service and workflow logs.

Cloud Composer Components

• Cloud Composer helps define a series of tasks as Workflow executed within an Environment
• Workflows are created using DAGs or Direct Acyclic Graphs
• A DAG is a collection of tasks that are scheduled and executed, organized in a way that reflects their relationships and dependencies.
• DAGs are stored in Cloud Storage
• Each Task can represent anything from ingestion, transform, filtering, monitoring, preparing, etc.
• Environments are self-contained Airflow deployments based on Google Kubernetes Engine, and they work with other Google Cloud services using connectors built into Airflow.
• Cloud Composer environment is a wrapper around Apache Airflow with components like GKE Cluster, Web Server, Database, Cloud Storage.

GCP Certification Exam Practice Questions

• Questions are collected from Internet and the answers are marked as per my knowledge and understanding (which might differ with yours).
• GCP services are updated everyday and both the answers and questions might be outdated soon, so research accordingly.
• GCP exam questions are not updated to keep up the pace with GCP updates, so even if the underlying feature has changed the question might not be updated
• Open to further feedback, discussion and correction.
