ABSTRACT:
Methods, systems, and computer-readable media for expressing fault correlation constrains to a developer of a service application are provided. Initially, the fault correlation constraints are identified by inspecting an architecture of resources comprising a data center. Based on the resources, sets of nodes that become concurrently unavailable due to a failure mode or update scheme are aggregated. These fault correlation constraints, upon being communicated to the developer, then may be incorporated into a service model produced thereby. Accordingly, the service model is tailored to the specific characteristics of the data center and is provided with instructions as to how to partition instances of the service application throughout the distributed resources of the data center. Thus, the fault correlation constraints provide a developer with insight into rules and structures on which the data center is constructed and assurances of a certain level of fault tolerance upon deploying the service application.
