Cross-Stratum Optimization Aware Provisioning Algorithm for Cloud Data Centers

As virtualization technology matured, the concept of virtual network environment has emerged. Because of the flexibility of virtualization, the cloud computing services can serve various needs of its customers more efficiently. However, in some of virtual network provisioning algorithms decisions are made without any consideration of underlying network. In this paper, we are focusing on cross stratum optimization opportunities, e.g., combined optimization of resources in the application and network stratums, and proposing and an efficient and optimized provisioning algorithm. We propose a CSO-aware provisioning algorithm and show its benefits over traditional resource allocation.
