Title: SCALING METHOD AND DEVICE FOR VIRTUAL MACHINE (VM)
Abstract:
A scaling method and device for a virtual machine (VM). The method comprises: when a new VM needs to be added in an application, determining a VM resource pool corresponding to the application (101); according to a parameter of the new VM that needs to be added in the application, searching in the determined VM resource pool for the VM conforming to the parameter (102); registering the found VM to a load balancer (LB); and starting the VM to provide a service for the application (103). That is, when a new VM needs to be added in an application, the VM satisfying the requirement of the application is selected from a VM resource pool that is created in advance, and the selected VM is registered and provides a service for the application. Therefore, the process for creating the virtual machine is not needed, the time for creating the virtual machine is reduced, and the scaling efficiency of the virtual machine is effectively increased.
