Managing engines and engine hosts

The engine is a service that runs to handle application analytics and task automation. Engines can be installed on the management console web server or on separate, dedicated engine servers. Given appropriate resources, you can configure the engine service to support as many parallel processes as your deployments require.

The engines perform all the processing actions for deployments and configurations. They also serve as the system scheduler and notification manager. You can control the behavior of the engines using certain system preferences. For more information, see Adding-or-changing-system-settings.
