(3) Logical components that can cover the set up legal agreement activity: The set up legal agreement
activity concerns the service agreement between the cloud service customer and the chosen cloud
service provider(s) see clause 8.4.2.8 in [ITU-T Y.3502]. The contract management logical component
(clause 6.4.3) manages all contracts in CSB in terms of SLA. So, the contract management logical
component fully covers the set up legal agreement activity.
(4) Logical components that can cover the assist CSC for accessing service activity: The assist CSC for
accessing service activity focuses on acquiring access information for a cloud service from a CSP who
provides the cloud service and forwarding of the access information to the CSC who requested the
cloud service so that the CSC understands how to access to and use the service. The service access
manager logical component (clause 6.4.4) manages access information of cloud services brokered
by a cloud service broker by acquiring access information from the CSP. Also, the service access
management logical component is capable of forwarding access information to a proper CSC. So,
the service access management logical component fully supports the assist CSC for accessing service
activity.
(5) Logical components that can cover the check and control service status activity: The check and
control service status activity focuses on assisting CSCs in cloud service controls such as stopping,
resuming and terminating cloud services. Also, this activity involves checking status of running cloud
services by monitoring so that a cloud service broker enforces service qualities agreed in a SLA
instead of CSCs. Since the service management logical component (clause 6.4.5) is a logical
component to manage controls and status of running cloud services brokered by a cloud service
broker, the service management logical component fully supports the check and control service
status activity.
