Why Composer: Managed Airflow on GCPāno cluster ops; integrated with BigQuery, GCS, Pub/Sub. Architectural logic: Creates Airflow environment; DAGs via GCS bucket; automatic upgrades. Supports Airflow 2.x, Celery/K8s executors. When to use: GCP-native pipelines; teams wanting orchestration without ops. Scalability: Auto-scaling workers; environment size configurable. Trade-offs: Cost can add up; less control than self-hosted. Cost: Environment size (CPU, memory) + worker costs. Compare to self-hosted (K8s + Airflow) for cost at scale.
Red Flag: 'We use Airflow' without managed vs. self-hosted context. Pro-Move: 'Composer for GCP; we evaluatedāmanaged worth the premium vs. our K8s ops overhead.'
