Disaster-aware data-center and content placement in cloud networks

Recent occurrences of disasters and targeted attacks have made disaster-resilient data-center network design an important issue. Network operators are investigating proactive and reactive measures to avoid huge data loss and service disruptions in case of a disaster. Disaster-aware data-center and content placement can mitigate the effects of such failures by avoiding placement in disaster-vulnerable locations. Compared to disaster-unaware approach, this approach can significantly reduce the risk, i.e., expected loss of content due to a disaster, in a cloud network.
