7 Lack of Automated, Programmable Network Today: VM on- boarding is measured in minutes 60+ % Percent of servers virtualized 93% Use storage virtualization? Use network virtualization But today: mul>- >er virtual- system connec>vity is measured in days. John Manville, Cisco IT; The Power of a Programmable Cloud, OFC 2013 (OM2D.2): It takes about 5 days from an end- end point of view to provision something like that (a mul>- >er system). Goal is to get at least to sub- one day. 7 Source: 2012 IBM Data Center Study: IBM Corporation

22 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.

34 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. 34
