Cloud computing has been created a revolution in the IT industry by providing enough resources while using it. Profitability of cloud computing had caused to create very large data centers around the world which contain thousand of computing nodes; But these centers consume too much electricity that leads to increase their operating costs and produce a large amount of carbon dioxide too. This research provides new techniques and algorithms for dynamic integration of virtual machines in the cloud computing centers. Our goal is to improve resources’ efficiency and reduce energy consumption of cloud computing centers without violating the limitations of desired service quality. Dynamic integration of virtual machines use changes of virtual machines’ workload and allocate them nearly to the optimization of physical nodes in order to minimize the number of the woken up physical nodes and consequently save energy. The proposed method is distributed, scalable and efficient in the compromise management between system efficiency and its consumed energy. The most important finding of this study is to provide a distributed method for the dynamic integration of virtual machines and heuristic algorithms.
