Cloud bursting technologies require network Agility The High Cost of Overprovisioning During the storage or virtual machine migration at the beginning of a cloudburst into the provider cloud, bandwidth of 1 to 10 gigabits per second will generally be required. However, for the remainder of that IaaS instance life-cycle, much lower bandwidth, rarely exceeding 200 megabits per second, is required.

Summary Optical network virtualization offers cloud providers & tenants high-bandwidth, low-latency connectivity on demand. Different models for optical network virtualization exist. A compromise between hiding the optical complexity and exposing the optical topology is required. Open approaches based on standardized GMPLS or emerging OpenFlow technologies are possible. 18
