Abstract: Method for distributing and controlling traffic in cloud computing system and cloud computing system using the same. The cloud computing system may include a plurality of local data centers located at different regions and a control center coupled to the plurality of local data centers through a network. The plurality of local data centers each may be configured to process packets from user equipments in order to provide a requested service. The control center may be configured to distribute packets transmitted to one local data center into at least one other local data centers based on at least one given factor when an amount of the packets to the one local data center exceeds a given threshold.

Abstract: A method and an apparatus may be provided for migrating a source virtual machine disk of a virtual machine from a first storage device to a second storage device while the virtual machine is running. The method may include creating a target virtual machine disk in the second storage device, replicating the source virtual machine disk of the first storage device to the target virtual machine disk in the second storage device, detecting variation of the source virtual machine disk, reflecting the detected variation on the replication stored in the target virtual machine disk in the second storage device, and assigning the target virtual machine disk of the second storage device as a designated virtual machine disk for the virtual machine.

Abstract: Provided are method and system for provisioning a virtual server. The method may include receiving a request to create a virtual server from a client, determining a client purpose of the requested virtual server, obtaining a previous virtual server usage pattern associated with the client, and creating a virtual server provision based on the client purpose and the previous virtual server pattern.
