2 Cloud Computing management

10.4.1 Resource fulfilment functionalities

This covers a set of functionalities for the fulfilment management of resources for the support of cloud
services. This functionality includes resource order management.
10.4.1.1 Resource order management

This set of functionalities manages the E2E lifecycle of a resource order request. This includes validating
resource availability as well as the resource order request.
NOTE – Resource order management functionality will typically communicate with service order management and
resource layer functionalities. Notifications can be issued to the service order management functionalities during the
resource order orchestration process (especially upon completion). Such notification can trigger other steps in the
service order management functionalities (e.g., resource order completion).
Resource order management functionalities include:

1) resource order orchestration and distribution. This functionality provides workflow and
orchestration capability across resource order management. This functionality has the ability to
distribute the resource order. It also provides functionality to track and manage the overall resource
order as well as to track the overall order;

2) resource order validation. This functionality validates the resource order request based on contract,
catalogue, and provisioning rules;
3) resource order tracking and lifecycle management. This functionality issues valid and complete
resource orders, and stores the order into an appropriate repository;
4) resource assign. This functionality addresses resource configurations which are needed to support
a service order.

10.4.2 Resource assurance functionalities
This set of functionalities covers the assurance management of resources in support of cloud services. These
functionalities include resource performance management, resource fault management and resource test
management. The role of particular functionalities is described below.

10.4.2.1 Resource performance management

This set of functionalities monitors, analyses, and reports on the performance of the CSP resources. This
includes the following functionalities:

1) resource performance monitoring. This functionality supports data collection and performance
monitoring of the CSP resources;
2) resource performance analysing. This functionality analyses the performance of the various CSP
resources;
3) resource performance management reporting. This functionality generates reports about the
performance of the CSP resources.

10.4.2.2 Resource fault management
This set of functionalities is responsible for the management of faults associated with the resources of CSP.
This includes the following functionalities:

1) resource fault monitoring. This functionality collects and monitors the operational status of the
resource layer;
2) resource fault analysis. This functionality relates and analyses the various fault events in the
resource layer;
3) resource fault correction and restoration. This functionality is responsible for repairing or
replacement of faulty resources;
4) resource fault reporting. This functionality provides reports about the various faults within the
resource layer.
