Cloud-Managed Airflow — Zero Infrastructure Overhead
For production workloads, many organizations prefer managed Airflow services that handle infrastructure, scaling, patching, and monitoring automatically.

Google Cloud Composer
# Create a Cloud Composer environment
gcloud composer environments create my-airflow \
--location us-central1 \
--image-version composer-2.9.0-airflow-2.10.0 \
--environment-size small
# Upload a DAG
gcloud composer environments storage dags import \
--environment my-airflow \
--location us-central1 \
--source my_dag.py
AWS MWAA (Managed Workflows for Apache Airflow)
# Create via AWS CLI
aws mwaa create-environment \
--name my-airflow \
--airflow-version 2.10.0 \
--source-bucket-arn arn:aws:s3:::my-airflow-bucket \
--dag-s3-path dags/ \
--execution-role-arn arn:aws:iam::123456789:role/mwaa-role \
--environment-class mw1.small
# Upload DAGs to S3
aws s3 cp my_dag.py s3://my-airflow-bucket/dags/
📘 Note
The choice between managed services usually depends on your existing cloud provider. If you're already on AWS, MWAA is the natural choice. If you're on GCP, Cloud Composer integrates natively with BigQuery, Dataflow, and GCS.

Self-Managed vs Managed: Decision Guide
| Factor | Self-Managed | Managed Service |
|---|---|---|
| Control | Full control over configuration | Limited to service options |
| Maintenance | You handle upgrades, patches | Automatic updates |
| Cost (Small) | Cheaper for small setups | Higher base cost |
| Cost (Large) | Expensive (team time) | More predictable |
| Time to Production | Weeks to months | Hours to days |
| Customization | Full (plugins, custom images) | Limited (varies by service) |
| Recommendation | Teams with K8s expertise | Most production teams |
