Abstract
Provided are a system and method for dynamically expanding a virtual cluster having one or more virtual machines (VMs), based on the resource availability of the virtual cluster and the type of the virtual cluster. The system for dynamically expanding a virtual cluster having one or more virtual machines (VMs), the system comprising a monitor unit which measures resource availability of a target virtual cluster and provides the resource availability to an expansion control unit, the expansion control unit which determines whether to expand the target virtual cluster based on the resource availability and determines a type and number of VM instances to be additionally allocated to the target virtual cluster by reflecting the resource availability and a type of the target virtual cluster and a virtual cluster configuration unit which modifies profile information of the target virtual cluster such that the determined number of VM instances of the determined type by the expansion control unit can be additionally allocated to the target virtual cluster.
