An engine runs pipelines.
You access Control Hub using a web browser. You use Control Hub to deploy engines to your corporate network, which can be on-premises or on a protected cloud computing platform.
When you view engine details in the Engines view, you can monitor the performance of the engine, the pipelines currently running on the engine, and the last time that the engine reported a heartbeat to Control Hub.
Engines registered with your organization send requests to Control Hub. To further secure your organization’s data, you can configure a list of trusted domains that can make requests to Control Hub. Control Hub verifies that each engine making a request to Control Hub on behalf of your organization belongs to one of the trusted domains.
