Energy-Efficient Cloud Computing Energy efficiency is increasingly important for future ICT Rapid growth of the demand for computational power has led to the creation of large-scale data centers Energy savings are achieved by continuous consolidation of VMs Page 2 Green Cloud Computing Energy distribution in the data centre [1] Page 3 Green Cloud Computing Introduction Elastic characteristic of Clouds In 2006 the cost of energy consumption by IT infrastructures in US was estimated as 4.5 billion dollars and it is likely to double by 2011 Virtualization technology allows : create several Virtual Machines on a physical server improved fault and performance isolation using live or off-line migration Page 4 Green Cloud Computing Vision and Potential of Cloud Computing Computer networks grow up and become sophisticated! Computing utilities based on a service provisioning model Users can access applications as services from anywhere in the world on demand Our Contributions to minimize the energy consumption Page 5 Green Cloud Computing Open Challenges Ability to transfer VMs between physical nodes using live migration Energy-aware Dynamic Resource Allocation QoS-based Resource Selection and Provisioning Optimization of Virtual Network Topologies Autonomic Optimization Efficient Consolidation of VMs Page 6 Green Cloud Computing
