Host resource dynamic capacity expanding and shrinking method and system

Abstract

The invention provides a host resource dynamic capacity expanding and shrinking method. The method comprises the following steps: detecting the real-time use condition of resources of a target host; when it is detected that the resource use condition of the target host meets the preset capacity expansion condition or capacity shrinkage condition, sending the resource use condition to target personnel in the form of a message, and notifying the target personnel of making a corresponding capacity expansion plan or a corresponding capacity shrinkage plan; after it is detected that the applicationservice of the target host is paused and a corresponding expansion plan or shrinkage plan is made, carrying out system backup on the target host; and after it is determined that the backup work of the target host system is completed, executing a capacity expansion plan or a capacity shrinkage plan on the target host, and after the capacity expansion plan or the capacity shrinkage plan to be executed is completed, notifying target personnel of starting the suspended application service of the target host and check the suspended application service. By implementing the method and the system, the phenomenon of unreasonable use of existing host resources can be overcome, flexible adjustment and saving of the host resources are realized, and the IT resource purchasing cost of enterprises is reduced.

Description

technical field [0001] The invention relates to the technical field of computer operation and maintenance, in particular to a method and system for dynamically expanding and contracting host resources. Background technique [0002] The use of host resources on the virtualization platform has always been irrational, and resources cannot be allocated reasonably according to actual usage requirements, which leads to wasteful and inflexible use of host resources, and increases the cost of enterprise IT resource procurement. Contents of the invention [0003] The technical problem to be solved by the embodiments of the present invention is to provide a method and system for dynamic expansion and contraction of host resources, which can overcome the unreasonable use of existing host resources, realize flexible adjustment and saving of host resources, and reduce enterprise IT resources. Resource procurement costs. [0004] In order to solve the above-mentioned technical problems...
