Abstract

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.

2. Cloud Computing

The ideas and concepts behind cloud computing have existed for many years. It was started in 1950’s along with mainframe computing. In the 1970’s virtualization concept was created in which one or more operating systems can execute simultaneously in an isolated environment. In the early 1990’s, telecommunication companies were offering virtualized private network services to its users. In the late 1990’s the term “cloud” signifies the computing space among provider and end user. Later on, the cloud providers like salesforce.com, amazon.com, Google gained the major internet marketplace and proved the power of cloud computing to the real world.
