A significant concern for Internet-based service providers is the continued operation and availability of services in the face of outages, whether planned or unplanned. This paper advocates a cooperative, context-aware approach to data center migration across WANs to deal with outages in a non-disruptive manner. It specifically seeks to achieve high availability of data center services in the face of both planned and unanticipated outages of data center facilities. Server virtualization technologies are used to enable the replication and migration of server functions. This paper proposes new network functions to enable server migration and replication across wide area networks (e.g., the Internet), and finally show the utility of intelligent and dynamic storage replication technology.
