Cloud computing utilizes arbitrary mega-scale computing infrastructures and is currently revolutionizing the ICT landscape by allowing remote access to computing power and data over the Internet. Besides the huge economical impact Cloud technology exhibits a high potential to be a cornerstone of a new generation of sustainable and energy-efficient ICT. The challenging issue thereby is the energy-efficient utilization of Physical Machines (PMs) and the resource-efficient management of Virtual Machines (VMs) while attaining promised non-functional qualities of service expressed by means of Service Level Agreements (SLAs). Currently, there exist solutions for PM power management, VM migrations, and dynamic reconfiguration of VMs.
