+### Ways to Use DataBuild in Production
+
+- **As a CLI build tool**: You can run DataBuild builds from the command line or in a remote environment - no build event log required!
+- **As a standalone service**: Similar to Dagster or Airflow, you can run a persistent service that you send build requests to, and which serves an API and web dashboard.
+- **As a cloud-native containerized build tool**: Build containers from your graphs and launch scheduled builds using a container service like ECS, or even your own kubernetes cluster.
