The Dynatrace Managed components are illustrated in the image below.

The Managed Cluster is responsible for managing various monitoring environments. A Managed Cluster typically comprises multiple nodes. Each Managed Cluster is assigned to a Cluster Management Console for its orchestration.
The Managed Cluster provides Mission Control with self-monitoring and licensing data to enable proactive support.
You need to obtain a license every time you want to set up a new Managed Cluster.
The Managed Installer handles the installation of Dynatrace Managed and all the necessary components:
All listed components are deployed on the first node you create when setting up a Managed Cluster, as well as on every subsequent node.
For each Managed Cluster you set up, there is a dedicated Cluster Management Console. The Cluster Management Console is a web-based UI for efficiently managing your Managed Cluster. From here you can view the deployment status of your Managed Cluster at any time.
With the Cluster Management Console, you can, for example:
Mission Control receives self-monitoring and license data from the Managed Cluster. Based on this data, the Dynatrace Mission Control team can proactively analyze and detect misconfigurations or potential incompatibilities with your installation. Mission Control, in turn, provides software updates for the Managed Cluster.
