Relationship between the logical components and
the activities of cloud service broker for CSB

(This appendix does not form an integral part of this Recommendation.)

Activities of cloud service broker for CSB consist of (1) acquire and assess customers, (2) assess marketplace,
(3) set up legal agreement, (4) assist CSC for accessing service and (5) check and control service status.

Figure II.1 – Relationship between the logical components and the activities of
cloud service broker for CSB

NOTE – Figure II.1 identifies reused activities from [ITU-T Y.3502] as well as new activities needed to support cloud
service brokerage.
(1) Logical components that can cover the acquire and assess customers activity: The acquire and
assess customers activity includes the tasks required to market and sell cloud services up to the
point where a cloud service customer agrees a contract to use one or more services, see
clause 8.4.2.6 in [ITU-T Y.3502]. The workspace and the product catalogue management logical
components cover the acquire and assess customers activity. The workspace logical component
(clause 6.4.1) provides a user interface for CSCs to help to present service requirements and to
request a cloud service. Also the product catalogue management logical component (clause 6.4.2)
provides information to potential CSCs about available services and associated SLAs and contract
terms. So, both logical components support the marketing and selling of cloud services up to the
point where a cloud service customer agrees a contract to use one or more services.

(2) Logical components that can cover the assess marketplace activity: The assess marketplace activity
focuses on assessing the current cloud services marketplace to find cloud service(s) that meet the
customers' requirements see clause 8.4.2.7 in [ITU-T Y.3502]. The workspace logical component
(clause 6.4.1) and the product catalogue management logical component (clause 6.4.2) cover the
assess marketplace activity. The workspace logical component provides a user interface for CSPs. In
workspace, a CSP can register, modify and remove a service list to be sold through a cloud service
broker. Also the product catalogue management logical component gathers cloud services from
multiple CSPs through workspace, registers those cloud services and, if needed, cancels the
registered cloud services. So, both logical components support assessing the current cloud services
marketplace to find cloud service(s) that meet the customers' requirements.
