Abstract

The present invention relates to cloud computing technology, in particular to a device and method for determining an operation for adjusting the number of virtual machines, and is used for providing a solution for flexibly configuring VMs. In the device for determining an operation for adjusting the number of VMs provided by the embodiments of the present invention, a data collection module acquires a load index of a system and the number of VMs used by the system at the current moment; and a first judgement module determines, according to the load index of the system and the number of VMs used by the system at the current moment, a first operation to be executed on the system, wherein the first operation comprises: increasing the number of VMs to be m, decreasing the number of VMs to be n, or keeping the number of VMs unchanged, with m and n being positive integers and being determined by the first judgement module according to the load index of the system and the number of VMs used by the system at the current moment. Since the increased or decreased number of VMs can be determined according to a load index of a system and the number of VMs used by the system at the current moment, and is no longer a fixed set value, the implementation thereof is more flexible.

Description

technical field [0001] The invention relates to cloud computing technology, in particular to a device and method for determining the number adjustment operation of virtual machines. Background technique [0002] Cloud computing (Cloud Computing) technology gathers computing, storage, service components, network software / hardware and other resources distributed on the network, and provides users with convenient and fast services based on resource virtualization. [0003] For traditional networks, one or more virtual machines can be used to realize the functions of network elements in the network. For example: for the mobile communication core network——Evolved Packet Core (EPC), the EPC network elements in the EPC network, such as: Mobility Management Entity (Mobility Management Entity, MME), Packet Data Network Gateway (Packetdata network GateWay, PGW), serving gateway (Serving GateWay, SGW), home subscriber server (Home Subscriber Server, HSS), etc., can be deployed in the ...
