• get nsdId, nsName and nsDescription parameter
• get a ns package by the given nsdId from ETSI Catalog Manager
• check if ns instance exists from the NFVO_NSINST database table
  • if it exists, log it exists
• create an ns instance id (uuid) and store it with other nsd info, status (NOT_INSTANTIATED) to NFVO_NSINST database table
• create an ns instance record (service-instance-id, service-instance-name, service-type, service-role) in AAI
• return 201 Created with the NsInstance
• Send NsIdentifierCreationNotification

• Get an ns instance id from the parameter
• create a job for the ns instance id
• create an occ id for the ns instance id
• Update the ns instance id row of the NFVO_NSINST database table for status (= INSTANTIATING)
• get a ns instance data from the NFVO_NSINST for the ns instance id
• get and store additional Parameters for NS
• get an VIM id from the cloud owner and cloud region parameters
• get an VNF VIM from he location constraints
• set the job status with 'Start Query NSD'
• get and parse a nsd for the ns package id
• modify nsd state
• get VNF list from the nsd 
• for each VNF,

  • select VNFM by leveraging AAI ESR
  • store VNF pararms in collection, with vnf info including vnfmInstanceId
• set vl vim id

    • get vnfdId and vimId
    • add vimId into VL array
• update NFVO_NSINST with the nsd model
• get PNF parameters
• get VNF parameters (from VNF params above)
• set up Plan Input with job_id, ns_inst_id, tosca plan, additional NS params, VNF params, PNF params)
• start workflows with the job_id, ns_inst, plan_input, occ_id)
  • get service template id from ETSI Catalog Manager
