1 Framework and requirements for cloud computing

• service level management;

• incident and problem management;
• platform and virtualization management;
• peer service management.

9.2.5.3.1 Service catalogue
The service catalogue functional component provides a listing of all the cloud services of a particular cloud
service provider. A service catalogue can contain/reference all relevant technical information required to
deploy, provision and run a cloud service.

9.2.5.3.2 Provisioning

The provisioning functional component provides the capabilities for provisioning services, both in terms of
the provisioning of service implementations and of access end points and the workflow required to ensure
that elements are provisioned in the correct sequence.

9.2.5.3.3 Monitoring and reporting
The monitoring and reporting functional component provides capabilities for:
• monitoring the cloud computing activities of other functional components throughout the cloud
service provider's system. This includes the functional components that are involved in the direct
use of cloud services by the CSC:cloud service users such as the service access and service
implementation (e.g., the invocation of a cloud service operation by a particular user). This also
includes functional components involved in the support of cloud services, such as functional
components in the OSS itself like the service automation functional component (e.g., the
provisioning of a service instance for a particular customer);
• providing reports on the behaviour of the cloud service provider's system, which can take the form
of alerts for behaviour which has a time-sensitive aspect (e.g., the occurrence of a fault, the
completion of a task), or it can take the form of aggregated forms of historical data (e.g., service
usage data);

• storage and retrieval of monitoring and event data as logging records.
There is a need to guarantee the availability, confidentiality and integrity of the logging records held by the
monitoring and reporting functional component. For multi-tenant cloud services, there is also a need to
design access to the records so that particular tenants can only gain access to information about their own
tenancy and about no other tenancy.

9.2.5.3.4 Service policy management
The service policy management functional component provides capabilities to define, store and retrieve
policies that apply to cloud services. Policies can include business, technical, security, privacy and
certification policies that apply to cloud services and their usage by cloud service customers.
Some policies can be general and apply to a cloud service irrespective of the customer concerned. Other
policies can be specific to a particular customer.
9.2.5.3.5 Service automation

The service automation functional component provides capabilities for service delivery including the
management and execution of service templates and the orchestration of services. The service automation
functional component holds the service templates which define the cloud computing activities and
workflows required to provision and deliver a specific entry in the service catalogue.
Cloud service provisioning can be automated in order to support scalable resource operations, including
configuration and charging.
Cloud service administration activities of the cloud service customer can be capable of being automated and
need not require any intervention by the cloud service provider.
