SO's primary function is the automation of end-to-end service instance provisioning activities. SO is responsible for the instantiation and configuration of VNFs in support of overall end-to-end service instantiation, operations and management. SO executes well-defined processes to complete its objectives and is typically triggered by the receipt of service requests generated by other ONAP components or by Order Lifecycle Management in the BSS layer. The orchestration procedure is either created manually or obtained from the Service Design and Creation (SDC) component of ONAP, where all service designs are created and exposed/distributed for consumption
Internally, SO is organized as a set of modules with well defined responsibility. External adapters (SDNC, OpenStack, VFC and SOL003) encapsulate most communication with external systems. Persistence is exposed to other SO modules – not externally, by DB adapters (Catalog and Request). The underlying workflow component resides in the BPEL BPMN Execution Engine. The BEPL BPMN Execution Engine also interacts with other ONAP systems such as App controllers, AAI and OOF-HAS. Interactions with SNC are hosted by the SDC Controller. Likewise the API Request Handler exposes SOs API for interaction with clients. Finally there is also a monitoring component that allows insight into the execution state of workflows.
