The MSO subsystem runs autonomously within OpenECOMP. Orchestration, in conjunction with policies, can be used to create flexible processes that are guided by business and technical policies and driven by process designers.

Orchestration exists throughout the D2 architecture and should not be limited to the constraints implied by the term “workflow” as it typically implies some degree of human intervention. Orchestration in D2 will not involve human intervention/decision/ guidance in the vast majority of cases. The human involvement in orchestration is typically performed up front in the design process although there may be processes that will require intervention or alternate action such as exception or fallout processing.To support the large number of Orchestration requests, the orchestration engine will be exposed as engine is a reusable service. With this approach, any Any component of the architecture can execute process recipes. Orchestration Services will be capable of consuming a process recipe and executing against it to completion. The Service model maintains consistency and reusability across all orchestration activities and ensures consistent methods, structure and version of the workflow execution environment.
