Framework and requirements for cloud computing                              1


            The  service  automation  functional  component  works  with  the  provisioning  functional  component  and
            service integration functional component to achieve its goals.

            9.2.5.3.6  Service level management
            The service level management functional component provides capabilities for managing the service levels of
            a particular cloud service, aiming to ensure that the cloud service meets the requirements of the SLA which
            applies to the service.
            The service level management functional component manages the capacity and performance relating to a
            cloud service. This can involve the application of service policies (e.g., a placement rule which aims to avoid
            single points of failure).

            The service level management functional component obtains monitoring information from the monitoring
            and reporting functional component in order to measure and record key performance indicators (KPIs) for
            the cloud service. Capacity is allocated or de-allocated based on the basis of these KPIs.

            The service level management functional component also keeps track of the overall state of allocated and
            available resources. The comparison of allocated capacity against cloud service performance KPIs can assist
            in the identification of current or potential bottlenecks, in support of capacity planning.

            9.2.5.3.7  Incident and problem management
            The  incident  and  problem  management  functional  component  provides  capabilities  for  the  capture  of
            incident or problem reports and managing those reports through to resolution.
            Incidents and problems can be detected and reported by the cloud service provider's systems, or they can
            be detected and reported by cloud service customers.
            9.2.5.3.8  Platform and virtualization management

            The platform and virtualization management functional component provides the capabilities for managing
            the underlying resources of the cloud service provider (compute, storage, networking) and for virtualizing
            the use of those resources (e.g., by means of hypervisors).

            The resources are typically organized into resource pools with key characteristics:
            •       standardized hardware componentry and configuration;
            •       readily expandable through the additional of new hardware capacity;
            •       automated shifting of resources as workload needs change;
            •       protection and isolation of neighbouring workloads and data;

            •       reduce and/or eliminate downtime through movement of workloads and data between resources;
            •       manage resource consumption based on goals (e.g., performance, availability, licences, energy use).
            9.2.5.3.9  Peer service management

            The peer service management  functional component provides capabilities for connecting the provider's
            operational support systems and business support systems to the administration capabilities and business
            capabilities of peer cloud service providers, in respect of peer cloud services that are used by the provider.

            The  peer service management  functional component  is  responsible  for  establishing  the  communication
            path(s) required, and for passing appropriate identity and credentials with requests made to the peer cloud
            service providers.

            9.2.5.4    Business support systems components
            The business support systems functional components encompass the set of business-related management
            capabilities dealing with customers and supporting processes.
