5 Conventions

In this Recommendation:
The keywords "is required to" indicate a requirement which must be strictly followed and from which no
deviation is permitted if conformance to this document is to be claimed.
The keywords "is recommended" indicate a requirement which is recommended but which is not absolutely
required. Thus this requirement need not be present to claim conformance.

In the body of this Recommendation and its appendices, the words shall, shall not, should, and may
sometimes appear, in which case they are to be interpreted, respectively, as is required to, is prohibited from,
is recommended, and can optionally. The appearance of such phrases or keywords in an appendix or in
material explicitly marked as informative are to be interpreted as having no normative intent.

6 End to end cloud resource management overview

The following clauses provide an overview of the general concepts of end to end cloud computing resource
management in a telecommunication rich environment.

6.1 Introduction
One significant value of cloud service providers will most likely be the rapid design, development, deployment
and management of cloud services. With the adoption of cloud computing service delivery capabilities,
multiple service providers will provide more cloud services as composite or mash-up services. Service
providers will increasingly have as their objective the rapid delivery of more customized, composite cloud-
based services tailored to various customer scenarios [b-FGCC Part 4].
In this Recommendation, the term multi-cloud refers to usage scenarios involving the use of various cloud
services implemented by more than one cloud service provider (CSP), though this multiplicity of CSPs may
not be visible to the cloud service customer (CSC). This is not to be confused with the multi-platform cloud
computing environment, which is a characteristic of cloud service providers that have chosen to offer a
variety of programming and runtime execution facilities to assist in the development and execution of cloud
applications. Nor should it be confused with the term "inter-cloud" which refers to the relationship and
interconnection between CSPs and not to the overall end to end system.

Cloud applications (also known as cloud workloads) are applications (i.e., software programs designed for a
specific purpose) that require execution in the cloud service provider's data centres in order for cloud services
