Framework and requirements for cloud computing 1

3.2 Terms defined in this Recommendation

This Recommendation defines the following terms:
3.2.1 cloud service image: An executable code with state information of virtual machine or container.
NOTE 1 – State information includes execution states, disk states and memory states of system, such as program
counter, registry, disk volume number, disk volume size, memory stack and information of allocated memory.
NOTE 2 – Cloud service image includes operating system, libraries, data files, applications, etc.
3.2.2 core cloud: A cloud computing, which manages resource pools including resources in the edge of
the network and enables cloud service.
NOTE – Enabled cloud service on the core cloud is provided by a cloud service provider (CSP).
3.2.3 distributed cloud: Distribution of cloud capabilities types to the edge of the network for enabling
cloud services with low latency and real time processing on limited bandwidth by interworking among pools
of physical or virtual resources.
3.2.3 edge cloud: A cloud computing deployed to the edge of the network accessed by cloud service
customers (CSCs) with small capacity resources enabling cloud service.
NOTE 1 – Enabled cloud service on the edge cloud is lightweight cloud service provided by a cloud service provider (CSP)
depending on cloud service category.
NOTE 2 – Lightweight cloud service refers to a portion of cloud service to reconfigure the functionality of cloud service
to fit on edge cloud such as base station and gateway with small capacity resource.
3.2.5 regional cloud: A cloud computing hosted from core cloud to particular geographical regions.

NOTE – Enabled cloud service on the regional cloud is entire or partial cloud service of core cloud provided by a cloud
service provider (CSP).
