Appendix I

Comprehensive view of management layers
(This appendix does not form an integral part of this Recommendation.)

Figure I.1 is an attempt at describing the management layers and how the service management interface
(SMIs) for each layer correlate with each other to offer a complete picture. The cloud computing data centre
implementation layers are depicted by large circles parallel to each other. The SMIs are depicted by small
blue circles containing the information required by the management system in order to achieve a holistic
view of the entire operation. The straight lines between each plane show the flow of information and
relationship between what is happening at each layer, depicting how each layer is related to and affected by,
the neighbouring one. Looking at the diagram in its entirety helps the viewer to realize why it makes sense
to expose consistent SMIs from each layer and to expose management information and telemetry in a
consistent matter that can then be rolled up into a comprehensive diagnostics and management solution
that can be used by a telecom operator offering and consuming cloud services and products.
