Table II.2 – Customer-oriented cloud service provisioning on distributed cloud

Use case

Name Customer-oriented cloud service provisioning on distributed cloud.
Abstract This use case describes customer-oriented service deployment on distributed cloud.
A main benefit of distributed cloud is provisioning of a cloud service in close proximity to
CSC. For the provisioning, methods to support customer-oriented cloud service provisioning
on distributed cloud are needed and is called service routing. The service routing includes
packet routing, service awareness, etc. By service awareness on distributed cloud, a cloud
service is deployed on a cloud in close proximity to the CSC or the request of a cloud service
is delivered to another cloud. Accordingly, the service routing on distributed cloud enables:
– scaling or migrating a cloud service for supporting mobility as shown in figure <An
example of scaling or migrating a cloud service for supporting mobility>;
– deploying and providing a cloud service for low response time as shown in figure < An
example of deploying and providing a cloud service for low response time>; and
