Virtualized IT infrastructures combined with virtual machine migration technologies have a potential to support IT services that are resilient to partial physical infrastructure failures caused by extreme events. This paper experimentally evaluates the migration of multiple VMs across long geographical distances - an activity that is required to move virtualized IT systems from a disaster site to a safe location. Taking into account the resource availability parameters observed after the Great East Japan Earthquake, experimental results show that if (1) service downtime in the order of minutes is acceptable, (2) VMs can be kept with small storage footprint, and (3) power and network are available for tens of minutes, it is possible to migrate tens of VMs from damaged sites to a very distant stable location.
