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

A method of controlling operation of a building control device using a virtual controller that is hosted on a cloud server having system resources, the building control device located at a building site, the method comprising:

• hosting the virtual controller on the cloud server, with some of the system resources selectively assigned to the virtual controller;
• providing an edge controller that is configured to control the building control device, the edge controller in operable communicating with the virtual controller over a network;
• sending control commands from the virtual controller hosted on the cloud server to the edge controller via the network to control the building control device;
• monitoring one or more performance parameters of the virtual controller hosted on the cloud server;
• and
• selectively adjusting the system resources of the cloud server that are assigned to the virtual controller based at least in part on the one or more performance parameters of the virtual controller.

A method of controlling operation of a plurality of building control devices using a plurality of virtual controllers that are hosted on a server having system resources, the method comprising:

• hosting the plurality of virtual controllers on the server, with each of the plurality of virtual controllers assigned a respective portion of the system resources of the server;
• sending control commands from the plurality of virtual controllers to control the plurality of building control devices;
• monitoring a work load and/or other performance parameters of each of the plurality of virtual controllers hosted on the server;
• and
• adjusting the respective portion of the system resources of the server that are assigned to one or more of the plurality of virtual controllers to accommodate changes in the work load and/or other performance parameters associated with one or more of the plurality of virtual controllers.
