Table II.3 – Distributed cloud infrastructure and service management

Use case

Name Distributed cloud infrastructure and service management
Description This use case describes the distributed cloud infrastructure and service management.
Distributed cloud infrastructure includes processing, storage, networking and other hardware
resources as well as software assets. Distributed cloud infrastructure management is the
management of hardware resources and software assets of distributed cloud.
Distributed cloud includes core, regional and edge clouds, which are different in size, hardware
types and software. For example, a distributed cloud resource may use a graphics processing unit
(GPU) or field-programmable gate array (FPGA) hardware for AR/VR scenarios and
microprocessor-based server instead of x86 server for some specified application. These
resources are distributed across various environments. Thus, resources need to be isolated and
protected in secure manner.
Distributed cloud provides flexible and agility network connectivity for core, regional and edge
clouds. The network connection can be changed on demand or based on policy, such as active-
standby policy.
The ultimate objective of distributed cloud is to provide distributed cloud services for the
customers. The distributed cloud encapsulates the capabilities of distributed cloud infrastructure
into various cloud services for the end customers.
Distributed cloud is a hierarchical system, in which each core cloud, regional cloud and edge cloud
could manage its local infrastructure and service, and the infrastructure and service of the whole
distributed cloud could be unified managed and coordinated by the distributed cloud
management.
