ELASTIC VIRTUAL MACHINE (VM) RESOURCE SCALING METHOD, APPARATUS AND SYSTEM

摘要

The present invention provides an elastic virtual machine (VM) resource scaling method, apparatus and system. The method comprises: determining, by a first node or an upstream node adjacent to the first node according to VM index information in the first node, that the first node reaches a predetermined threshold for performing elastic VM resource scaling; and performing elastic VM resource scaling on the first node by using the upstream node of the first node. The problem in the related art of excessive information exchange with an NFVO and high impact on the NFVO is solved, thereby achieving the effect of reducing the information exchange with the NFVO and lowering the impact on the NFVO.
