SYSTEM AND METHOD FOR DYNAMIC MANAGEMENT OF VIRTUAL MACHINES IN A CLOUD COMPUTING ENVIRONMENT

摘要

The invention relates to a dynamic management system of virtual machines in a cloud computing environment, and a corresponding method, with application to the optimized management of the placement of virtual machines {VMi} on servers {Sj}, able to host one or several virtual machines, in this environment 1, in order to consolidate the physical infrastructure. The system is adapted to receive a placement request on all or part of the servers of N new virtual machines {VMn}, with N≥1, and comprising a module 2 for determining an investment plan (x1n, j), ( x2n, j) new virtual machines on the servers, and a module 3 placing a new virtual machine on one of the servers and moving a virtual machine from one to another of the servers. Module 2 determines: - a general placement plan (x1i, j) of the N new virtual machines and virtual machines already hosted on the servers, which includes the placement plan (x1n, j) of the N new virtual machines on the servers combined with a plan for moving the virtual machines already hosted on the servers, and a cost of this general investment plan, - the placement plan (x2n, j) of the N new virtual machines on the independent servers, without a plan for moving the virtual machines. virtual machines already hosted on the servers, and a cost of this independent placement plan; - a general travel plan (x2i, j) of the N new virtual machines and virtual machines already hosted on the servers, which includes the movement of the set of virtual machines including the N new virtual machines placed according to the independent displacement plan, and a cost of this general displacement plan, and compares the cost of the general investment plan with the sum of the cost of the independent investment plan and the cost of the overall travel plan, and the investment module implements the appropriate investment plan based on the outcome of the comparison.
