Green Cloud and Virtual Machines Migration Challenges
Cloud computing, currently, is one of the most efficient technologies over the IT and global application environments. This new environments has become one the major an effective working environment for small and medium scale enterprises. No one can deny the importance of the cloud computing, but replacing conventional data centers by cloud data centers need more attention. One of the important sides of cloud data centers is down time. To achieve this approach, data centers need to be active all the time and this approach needs more power. Thus, one of our concerns is about consuming more energy, because more energy needs more energy production. Therefore, traditional cloud data centers need huge electricity energy for running servers and cooling systems for example. Electricity production need carbon-based fuels, principally coal, oil, and natural gas cause the emission of the greenhouse gases like carbon dioxide (CO2). This emission may cause the global warming that has direct effects on humankind environment. To decrease greenhouse gases, it needed to consume less carbon-based fuels and green cloud data centers based on less consuming energy that known as high-efficient data centers. In green cloud we try to reduce the number of active devices and consume less electricity energy. The green data centers toke an advantage of the VMs ability of copying, deleting and moving across the data center. This action over servers may cause serious effect over all part of data centers in designing green data centers and in this paper bolds these challenges on this path.
