Certain embodiments enable resources assigned or allocated to an operating virtual machine (VM) to be modified while the VM is operating and without having to stop, restart, or reboot the VM. The modification may correspond to increasing or decreasing the amount of a resource being assigned to the VM. In this manner, resources assigned to a VM at the time of creation of the VM are not static and can instead be dynamically changed while the VM is operating without having to stop, reboot, or restart the VM. In some embodiments, the changes to the resources allocated to one or more VMs provided for a user (e.g., a customer) may be made according to or in response to a Service Level Agreement (SLA) entered into by the user, in response to an event such as a failover or switchover event, and the like.

The method includes sending data units by the senders over the communications network on working circuits, applying network coding to form a combination of data units from data units from a plurality of the senders, and sending the combination of data units over the communications network on a backup circuit. If one or more link failures occur in the working circuits resulting in loss of one or more of the data units, then the method further includes recovering the one or more of the data units from the combination of data units transmitted on the backup circuit. The backup circuit used to carry the combination of data units may be implemented in-band with user data or may be implemented as out-of-band backup circuits.

Systems, methods and computer program products that enable efficient roaming of virtual mobile devices. In one embodiment, multiple PoP locations having a set of common master images are maintained. A communication from a mobile device received at a central facility identifies a user, a location and a type of the mobile device. The central facility determines performance measures for the PoP locations and identifies a preferred PoP location in response to the communication. If the preferred PoP location has available capacity, the central facility directs the preferred PoP location to provision resources and instantiate a virtual device from a selected master image corresponding to the mobile device. If the preferred PoP location persistently stores a user data volume for the user, the virtual device is attached to the stored user data volume. Otherwise, data is transferred from the user's data volume to a cache attached to the virtual device.
