Abstract
The rapid growth in demand for computational power driven by modern application services along with the drop in storage and bandwidth pricing has led to the shift to Cloud Computing paradigm and to the establishment of large scale virtualized data centers, which consume enormous amounts of electrical energy.
In our work, we focus on minimizing the energy consumption of cloud computing architectures using task consolidation and migration techniques. We also try to minimize the task delays associated with the profit loss of the provider. We assume that a number of consumers send their applications (tasks) and are processed by a number of resources that the provider offers.
We first implemented an energy – conscious task consolidation algorithm from the literature on an extensive framework, CloudSim ToolKit. We then designed and incorporated into our system a live Virtual Machine migration process in order to reduce the energy consumed by the system. As a last step, we implemented MinDelay, an algorithm which minimizes the task delays while taking provider profit into account; we combined MinDelay with our energy-efficient approach in order to study the potential gains of the hybrid scheme.
