Sustainable Cloud Computing
Cloud Computing is rising fast with its data centres growing at an unprecedented rate. However, this has come with concerns over privacy, efficiency at the expense of resilience, and environmental sustainability, because of the dependence on Cloud vendors such as Google, Amazon and Microsoft. The authors' response is an alternative model for the Cloud conceptualization, providing a paradigm for Clouds in the community, utilizing networked personal computers for liberation from the centralized vendor model. Community Cloud Computing (C3) offers an alternative architecture, created by combing the Cloud with paradigms from Grid Computing, principles from Digital Ecosystems and sustainability from Green Computing, while remaining true to the original vision of the Internet.
