Cloud computing resource scheduling method based on repeat removing

Abstract

The invention discloses a cloud computing resource scheduling method based on repeat removing. The method includes the following steps that compute nodes send resource scheduling requests to a management node; the management node evaluates the system load level of each compute node; whether available cloud computing resources can satisfy the scheduling requests or not is judged, if not, the scheduling process is ended, and if yes, the scheduling process is continued; the management node calculates the semantic similarity between a virtual machine to be scheduled and virtual machines running on the compute nodes; the management node weights the sum of the semantic similarity of the virtual machine to be scheduled and the virtual machines running on the corresponding compute nodes so as to find out a selectable target compute node; whether the selectable target compute node is unique or not is judged, if yes, the last step is executed, and if not, the steps are sequentially executed; a selectable node is randomly selected as the target compute node; the target compute node distributes the computing resources to the virtual machine to be scheduled so that the virtual machine to be scheduled can run. The method can simultaneously optimize the I / O performance of a cloud computing system, keep node cluster loads balanced, and improve the use ratio of the resources.

Description

technical field [0001] The invention belongs to the field of virtualization and cloud computing, in particular to a deduplication-based cloud computing resource scheduling method. Background technique [0002] Cloud computing can use virtualization technology to abstract the computing resources of each physical node in the data center into multiple virtual machines with independent computing capabilities, and provide users with virtual machine-based computing services on demand through the Internet. Due to the dynamic changes in user computing service requirements, uneven distribution of physical node resources, dynamic expansion of cloud computing systems, and replacement of physical nodes, cloud computing resource scheduling technology has become one of the key technologies of cloud computing. , Stable and reliable operation plays a vital role. [0003] In a cloud computing system, a virtual machine runs on a cluster of physical computing nodes, and the file data of the v...
