Providing high availability in a diverse client demand scenario is a key challenge of cloud computing providers. A possible approach to protect cloud systems from natural disasters corresponds to the utilization of redundant data centers located far enough apart. The time to migrate a virtual machine (VM) from a data center to another increases due to distance. As this time impacts the overall system behavior, performability evaluation considering VM migration time and different load balances… CONTINUE READING
