| description: | The controller is the brain of the Deis platform. |
The controller is the "brain" of the Deis platform. A controller manages :ref:`Clusters <cluster>`, comprised of groups of nodes providing proxy and runtime services for the application platform. A single controller manages multiple clusters and applications.
The controller is in charge of:
- Authenticating and authorizing clients
- Processing client API calls
- Managing a cluster with nodes to host services
- Managing containers that perform work for applications
- Managing proxies that route traffic to containers
- Managing users, keys and other base configuration
The controller stack includes:
- Django API Server for handling API calls
- Celery, backed by Redis, for dispatching tasks
