Optimal Provisioning for Elastic Service Oriented Virtual Network Request in Cloud Computing
In the cloud computing paradigm users access applications/services hosted and run on virtual machines in interconnected datacenters. Applications from the same user may need to interact and change data or information, thus, the authors may abstract the applications/services request from same user as a Virtual Network (VN). To improve performance and resource efficiency, it is critical that the VN request be optimally provisioned given the current resource state of the datacenters. However, all of the existing research about optimal VN provisioning conducted for deterministic services.
