Method and device for realizing service isolation in cloud computing system, and cloud server

Abstract

The embodiment of the invention provides a method and a device for realizing isolated services in a cloud computing system, and a cloud server. The method comprises the following steps of: monitoring a progress of an application program running in the cloud server; and when centre process unit (CPU) resources occupied by the progress are greater than or equal to a preset threshold value, sending a pause signal to a scheduling unit corresponding to the progress so as to temporarily stop the scheduling unit from distributing the CPU resources to the progress. By the embodiment of the invention, the problem of a finite number of services isolated by a virtual machine due to a large quantity of system resources, occupied by a mapping of a virtual machine monitor (VMM) from the virtual machine to a physical machine, in the cloud computing system in the prior art can be solved, so that isolation of more services can be realized; therefore, the resource utilization rate of the cloud computing system can be increased.

Description

technical field [0001] Embodiments of the present invention relate to information processing technologies, and in particular, to a method and device for realizing service isolation in a cloud computing system, and a cloud server. Background technique [0002] The cloud computing system includes a "cloud" with powerful computing capabilities, that is, a cloud server, and a user terminal, that is, a cloud terminal. The terminal is simplified into a simple input and output device, and can enjoy the powerful computing and processing capabilities of the cloud server on demand. In a cloud computing system, in order to achieve business isolation, a cloud server (referred to as a physical machine) can usually be virtualized into multiple virtual cloud servers (referred to as a virtual machine) through a virtual machine monitor (Virtual Machine Monitor, referred to as VMM). Different business applications run on each virtual machine. [0003] However, the virtual machine actually r...
