Virtual machines (VMs) offer an economic and scalable solution to efficiently utilize the physical resources. In this paper, we investigate the optimization of VM placement in IP over WDM core networks considering a VM workload that varies with the number of users served by the VM. Our results show that the optimal VM placement in distributed clouds yields up to 23% total power saving compared to a single cloud.
