HA dependency between a master module and slave modules

This video shows HA (High Availability) dependency between a master module and slave modules.
The master module is replicating directories for 2 slave modules.
The slave modules manage restart of Microsoft Paint and Notepad on software failure.
And the master module manages the global failover on hardware failure.
