The Service Order Management component is the entry point of the Product Domain. It is in charge of Customer-Facing-Service (CFS) delivery of resources (network and service platforms equipment). This component exposes in particular the API" ServiceOrder". It is triggered when the Product Order Orchestration Management component calls this API to request CFS delivery. To achieve delivery of a CFS, the SOM orchestrates the CFS delivery process which: • Identifies possible RFS and chooses one, using the catalogue and technical inventory. • Selects the resources (servers, equipment, etc.) and their instances. • Requests the ROM to update selected resource instances to deliver CFS. Request sent to the ROM contains the CFS and the list of configured resource instances to update.
