Abstract
Embodiments described herein are directed to updating the various software associated with a distributed application in a piecemeal fashion. All instances of the software are analyzed and separated into different portions, called “roles.” Each instance of a role is strategically assigned to an update domain based on the structural information included in the service model of the distributed application. The distributed application is upgraded one update at a time by selecting an update or host update domain, bringing the roles assigned thereto offline, updating the offline roles, bringing the roles back online, and repeating for other update or host update domains.
