5                                            Intercloud and interoperability


            This function includes the following.

            –       Service provisioning automation. This allows automation of workflows to realize inter-cloud service
                    deployment between peer CSPs, without manual operations.
                    NOTE 1 – Typical use cases of service provision automation include: automatic recovery, scale-in and scale-
                    out, switchover and switchback of cloud services with peer CSPs.
            –       Service configuration automation. This allows automation of workflows to realize automated inter-
                    cloud service configuration, without manual operations.
                    NOTE 2 – Service provisioning and configuration automation allows for policy-based automated workflows for
                    inter-cloud services.

            7.2.6   Service level management
            The service level management function manages the service levels of a particular inter-cloud service to meet
            the requirements of the SLA.
            This function includes the following.

            –       SLA  negotiation. This  allows  for  negotiating  inter-cloud  service  level  information,  e.g.,  capacity,
                    performance, between peer CSPs.
            –       Service level tracking. This allows for measuring and recording of key performance indicators (KPIs)
                    of inter-cloud service between peer CSPs according to the monitoring results.
            –       Service  performance  management.  This  allows  for  adjusting  of  particular  inter-cloud  service
                    performance based on service performance tracking results to meet the requirements of the SLA.
            –       Service capacity management. This allows for identifying of current or potential capacity bottlenecks
                    by comparing the allocated inter-cloud service capacity with KPIs, and planning inter-cloud service
                    capacity to meet the requirements of the SLA.

            7.2.7   Incident and problem management
            The incident and problem management function detects and reports inter-cloud incidents and problems.
            This function includes the following.

            –       Incident  and  problem  detection.  This  allows  for  capturing  of  inter-cloud  incidents  or  problems
                    between peer CSPs.
            –       Incident and problem reporting. This allows for providing and exchanging of inter-cloud incident or
                    problem reports to peer CSPs.

            7.2.8   Peer service management
            The peer service management function allows for connecting of OSS and BSSs of a peer CSP, by adapting an
            inter-cloud management application programming interface (API).
            This function includes:

            –       Inter-cloud  connection  management.  This  allows  for  managing  of  connectivity  with  peer  CSPs
                    involved in an inter-cloud relationship.
            –       Access of the BSSs of a peer CSP. This allows for accessing to the inter-cloud BSSs of peer CSP with
                    appropriate identity and credentials to provide business capabilities. The identity and credentials
                    are provided by inter-cloud security (see clause 7.4). The functions of inter-cloud BSSs can be found
                    in clause 7.1.
            –       Access to the OSS of a peer CSP. This allows for accessing to the inter-cloud OSS of a peer CSP with
                    appropriate  identity  and  credentials  to  provide  administration  capabilities.  The  identity  and
                    credentials are provided by inter-cloud security (see clause 7.4). The functions of an inter-cloud OSS
                    can be found in clause 7.2.
            –       Inter-cloud management API adaptation. This allows for adapting of an inter-cloud BSS- and OSS-
                    related API from a peer CSP.
