Resource Management by Virtual Machine Migration in Cloud Computing

Cloud computing is a quickly emerging field in computer science. It offers a wide variety of advantages over the traditional computing systems. Fast provisioning of resources, low upfront payment, minimal infrastructure management issues and so on. These enticing benefits offered by cloud computing has made it viable for many small organizations and keen individual developers as well. All of this cloud computing is possible with the help of datacenters running thousands of servers all through day and night, which means a lot of power is consumed by the servers alone. These datacenters in itself needs a lot of power for cooling, security and other essentials required to run a datacenter. All of this energy consumption by all of the datacenters worldwide means only one thing, a lot of carbon dioxide emissions, this carbon footprint can cause severe damage to the atmosphere in the years to come with this ever increasing need for cloud computing. All of the servers running in the datacenter are not necessarily running at full capacity, hence the cloudlets can be consolidated into a few servers whenever possible, so that servers that are being utilized below capacity can be turned into a less power consuming state and thereby overall reducing the cumulative power consumption of the servers in the datacenter.
