Abstract: System and method for designing and deploying a building-related service in a building automation management system (BAMS) based on a software-defined master system (SDMS) architecture. The master system of the BAMS comprising a plurality of building automation systems (BASs) receives a request to create a building-related service involving dynamic coordination between at least two BASs. The request may include a workflow comprising a set of actions and configurations defining the building-related service. The master system uses system description data generated from the workflow to instantiate a blueprint that defines data exchanges with the at least two BASs, information about target hosts, and any dependencies to be resolved. Upon parsing the blueprint to resolve any dependencies, the master system builds a deployment plan that includes a sequence of steps and configurations for implementing the building-related service.
