Master Infrastructure Controller (mic)
Description
Manages changes to the entire system infrastructure, manages the distribution and synchronization of configurations and the upgrade process.
Reserved in Active-Passive mode. Not scalable.
If the role is unavailable, the system continues to function properly, eliminating the ability to change the configuration and upgrade the system. The zone from which the master site is inaccessible remains without configuration changes or updates until it is connected. The system can be broken up into several zones, each of which continues to perform its functions separately.
