VM placement algorithm based on recruitment process within ant colonies

The Cloud computing forges the shape of the current era and the following ones based on delocalized IT infrastructure and sharing resources. However, the rebellious rise of cloud computing comes with concerns over energy consumption. Numerous reports which inspected Cloud energy consumption showed that the Cloud is an energy monster, specifically the data centers that holds 2% of overall energy consumed in the world on 2011 [6]. More closely, it has been proven that the servers (Physical machines PM) are the most energy-hungry elements of the data center [7]. Server consolidation based on virtualization is a key mechanism for energy consumption taming. Within this context, our aim in this paper is to propose a VM Placement Algorithm Based on Recruitment process within Ant Colonies proposed by Bonabeau [12] that seeks to maximize PM resources exploitation along with maximizing resources balance. The exprimental results showed that our algorithm generates always a significantly good solution.
