Embodiment 1

[0063] Such as figure 2 According to the present invention, the multi-target virtual machine scheduling method for multi-cloud resource management includes the following steps:

[0064] Step 1: Collect cloud allocation records in real time, and obtain the running cloud list P and special virtual machine set PV from the cloud allocation record data set R.

[0065] In order to facilitate the resource management of Duoyun, virtualization technology is adopted and virtual machine instances are used to represent the resources of Duoyun. In Duoyun, the system log file saves the distribution record log of Duoyun in real time. When the mobile service requests virtual machine instances for resource hosting, according to the number of requested virtual machine instances, the background will generate the same number of cloud allocation records. Assuming that at time t, there are M pieces of cloud allocation records in the data set of cloud allocation records, denoted as R={r 1 ,r 2 ...

Abstract

The invention discloses a multi-target virtual machine scheduling method for cloud resource management, and the method comprises the steps: collecting a cloud distribution record in real time, and obtaining a running cloud list P and a special virtual machine set PV from a cloud distribution record data set R; traversing the cloud distribution record data set R to obtain the free space of each cloud in the running cloud list P; calculating a virtual machine scheduling strategy set corresponding to all the clouds, and assessing the migration cost caused by the virtual machine scheduling strategy and the executed cloud load balancing variance according to the free space of the clouds; calculating a load balancing variance set and a migration cost set according to the executed cloud load balancing variance and migration cost; and through a simple weighting method and a multi-standard decision algorithm, seeking a virtual machine scheduling strategy with an optimal joint optimization effect. According to the method, the migration generation time of the virtual machine and the load balancing variance of the cloud after migration are comprehensively considered, the index is optimized while the cost requirement of migration is met, the resource idle possibility is reduced, and the energy consumption is reduced.

Description

technical field [0001] The invention relates to the fields of data processing and mobile cloud computing, in particular to a multi-objective virtual machine scheduling method and system for multi-cloud resource management. Background technique [0002] With the development of mobile network technology and the increasing demand of users for mobile services, more and more mobile terminal access services are provided to users. However, with the growth of user demands, the types of mobile applications are also increasing, especially many applications that require high computing power and delay time. The execution requirements of these applications have far exceeded the processing capabilities of the mobile device itself, resulting in longer delay times and faster power consumption. When cloud computing is introduced, mobile devices can send computing tasks to the remote cloud platform for execution, use the computing resources of the cloud data center to perform computing tasks...
