Figure 6-3 – Edge, regional, core cloud configuration in distributed cloud

Table 6-1 describes the generic model of distributed cloud by composing two or more clouds among core,
regional and edge cloud. The end device in the figure represents CSCs' devices such as mobile phones,
personal computers (PCs), laptops, etc.

Table 6-1 – Distributed cloud configuration model

Model Description
Model 0

Model 0 is a shape of cloud computing.
Model 1
(Regional – Core)

Model 1 is a shape of a distributed cloud in which the core cloud and the regional
cloud are configured together. Cloud services are provided from one or more
clouds among the regional cloud and the core cloud.
The regional cloud is hosted for a cloud service from the core cloud to a particular
region to support localization of cloud services. The regional cloud assists the core
cloud by mitigating traffic of cloud service.
