- MAY be based on the micro-services architecture
Below is a formal definition of the Tango Controls System.
; Tango Control System consists of set of device_servers and clients applications tango_controls_system = *device_server *client [tango_database] [access_control] ; Device Server instantiate admin_devcie and other devices device_server = admin_device *device tango_database = device ;where device provides functionality of Tango Database access_control = device ;where device provides functionality to manage access to Tango Controls System admin_device = device ;where device provides functionality to manage a device_server it belongs to and devices instantiated by this device_server
