Abstract

The present disclosure relates to resource sharing between clouds. According to the present disclosure, a control apparatus comprises: a resource monitor, a resource decider, a secondary cloud determiner, and a deployer. The resource monitor monitors a resource usage state of a cloud in a cloud group. The resource decider, with a creation request for a new application to a primary cloud in the cloud group serving as a trigger, decides whether or not a resource for deploying all components for constructing the new application is in the primary cloud. Based on the size of available resources if a surplus component that cannot be deployed in the primary cloud is deployed in a cloud other than the primary cloud in the cloud group, the secondary cloud determiner determines a secondary cloud in which the surplus component is to be deployed. The deployer deploys the surplus component in the secondary cloud.

First claim

1 . A control apparatus that comprises one or more processors and, with at least one of the one or more processors, performs:
monitoring a resource usage state of a cloud in a cloud group; with a creation request for a new application to a primary cloud in the cloud group serving as a trigger, deciding whether or not a resource for deploying all CNFs (Containerized Network Functions) for constructing the new application is in the primary cloud; based on a size of available resources if a surplus CNF that cannot be deployed in the primary cloud is deployed in a cloud other than the primary cloud in the cloud group, determining a secondary cloud in which the surplus CNF is to be deployed; and deploying the surplus CNF in the secondary cloud.

2 . The control apparatus according to claim 1 , wherein the secondary cloud is the cloud with the greatest size of available resources.

3 . The control apparatus according to claim 1 , which further determines the secondary cloud based on a distance between the primary cloud and a cloud other than the primary cloud.

4 . The control apparatus according to claim 3 , wherein when there is a plurality of clouds with the same size of available resources, the secondary cloud is the cloud with the shortest distance from the primary cloud among the plurality of clouds with the same size of available resources.

5 . The control apparatus according to claim 3 , wherein the secondary cloud is the cloud with the shortest distance from the primary cloud.

6 . The control apparatus according to claim 1 , wherein the size of available resources of a cloud (i) in the cloud group is calculated using an evaluation function Q i .

f max i is a maximum number of CNFs that can be placed in the cloud (i),
f sum i is a sum obtained by adding a number of CNFs for constructing the new application, which have been requested to be placed in the cloud (i), to a number of CNFs already placed in the cloud (i), and
f d is a number of surplus CNFs that cannot be deployed in the primary cloud among all CNFs for constructing the new application.
