Method and system for managing virtual controllers in a building management system

A control system for controlling operation of a plurality of building control devices, the control system comprising:

• a pool of virtual controllers hosted on a computing device, each of the virtual controllers in the pool of virtual controllers configured to provide control commands for controlling one or more associate building control devices of the plurality of building control devices over a network;
• a plurality of edge controllers, each of the plurality of edge controllers associated with at least one building control device and configured to receive via the network and execute control commands from one or more of the plurality of virtual controllers of the pool of virtual controllers to control the associated one or more building control devices;
• an orchestrator configured to monitor one or more operational characteristics of each of the plurality of virtual controllers in the pool of virtual controllers hosted on the computing device;
• and
• the orchestrator further configured to automatically replace a virtual controller in the pool of virtual controllers with a new virtual controller and mapping one or more of the plurality of edge controllers that were associated with the replaced virtual controller to the new virtual controller when one or more of the operational characteristics of the replaced virtual controller meets one or more predetermined characteristics.
