Advances in Green Cloud Computing

Cloud computing is witnessing tremendous growth at a time when climate change and reducing emissions from energy use is gaining attention. With the growth of the Cloud, however, comes an increase in demand for energy. There is growing global awareness about reducing greenhouse gas emissions and healthy environments. Green computing in general aims to reduce the consumption of energy and carbon emission and also to recycle and reuse the energy usage in a beneficial and efficient way. Cloud data centers consume inordinate amounts of energy and have significant CO2 emissions. This chapter gives an overview about green cloud computing and its evolution, surveys related work, discusses associated integrated green cloud architecture (green cloud framework), innovations, and technologies, discusses green cloud computing scenarios, and highlights future work and challenges that need to be addressed to sustain an eco-friendly cloud computing environment that is poised for significant growth.
