II.4 Distributed cloud infrastructure and service provisioning
Table II.4 – Distributed cloud infrastructure and service provisioning
Use case
Name Distributed cloud infrastructure and service provisioning.
Description This use case describes the distributed cloud infrastructure and service provisioning.
Distributed cloud can provision infrastructure and deliver service among core, regional and edge
cloud.
The distributed cloud infrastructure contains various hardware and software, including servers,
storage, network devices and software. The edge cloud especially is resource-constrained due to
space and power. The infrastructure provision process includes hardware initiation, network
configuration and software installation. After provisioning, the services including security
functions and suites can be provided based on the infrastructure. Also, if a cloud service needs
to use an edge cloud resource, it is reconfigured or developed to run on the edge cloud with small
capacity and heterogeneous resources.
The distributed cloud infrastructure can be maintained and upgraded by distributed cloud
management. The provisioning is a policy-based process so it can be done automatically on
distributed cloud resources.
Once the distributed cloud infrastructure has been provisioned, the cloud service should be
deployed and delivered rapidly to the suitable distributed cloud resource by high-speed and
reliable network connectivity based on service's SLA, such as required resources, maximum
latency, required or useful services, etc. The deployed service can be maintained and upgraded
based on global management. For accurate global management, status information of cloud
service and distributed cloud resource are synchronized from edge/regional cloud to core cloud.
