Abstract

The invention provides a method and a device for removing virtual machines and an automatic elastic cluster. The method comprises steps as follows: preset conditions allowing a virtual machine cluster to remove virtual machines in the virtual machine cluster are monitored, the preset number N of the virtual machines to be removed is acquired, and N is a positive integer; M candidate virtual machines in the virtual machine cluster are selected to execute service data protection operation, and the service data protection operation is used for guaranteeing service data of the candidate virtual machines, wherein M is a positive integer larger than N; after service data protection operation in any candidate virtual machine of the M candidate virtual machines is confirmed to have been executed, the candidate virtual machines completing service data protection operation are removed, the number of the removed candidate virtual machines is ensured to reach N, and service data protection operation of the remaining (M-N) candidate virtual machines is suspended. According to the method and the device for removing the virtual machines and the automatic elastic cluster, the user experience can be improved.

Description

technical field [0001] The invention relates to cloud computing technology, in particular to a method, device and automatic elastic group for removing a virtual machine. Background technique [0002] In the prior art, cloud service (Cloud Service) is more and more widely used. Cloud service providers conduct unified management, scheduling and allocation of a large number of computing, network, storage and other resources. For users, cloud service providers provide a huge resource pool for users to use. The advantages of cloud services include on-demand allocation of resources (On-Demand), payment according to actual use (Pay-as-you-go), etc. advantage. Generally speaking, cloud service facilities are considered to be composed of three levels, from bottom to top: Infrastructure-as-a-Service (IaaS), Platform-as-a-Service (Platform-as-a-Service), And Software as a Service (Software-as-a-Service, SaaS). [0003] Auto Scaling is an important means for cloud computing to achie...
