With the increasing popularity of cloud computing, the cloud data center suffers from both limited resources and the variation of users' requests. One important feature of cloud computing is on-demand scaling, enabling the fluctuation of one user's resource demand. However, amongst previous paper concerning the Virtual Machine (VM) placement in data centers, satisfying requested resources of VMs is the primary objective, which neglects the future demand variation. In this paper, the authors propose the concept of elasticity, referring to how well the data center can satisfy the growth of the input VMs' resource demands under both the limitations of Physical Machines (PMs) capacities and links capacities.
