Theory and Algorithms for Emerging Cloud Computing and its Sustainability

Abstract

With dramatically increasing demand on computing and storage systems, IT infrastructures have been scaled tremendously which results in huge amount of energy consumption, heat dissemination, greenhouse emission and even part of climate change. By taking advantage of virtualized resources, cloud computing presents an attractive means to address the challenges while realizing the potential of green and services computing. Consequently, com- putational scientists are turning their attention to emerging cloud computing architectu res. As such, green and sustainable computing has come to the picture seeking solutions for computing and IT infrastructures to be en- ergy ecient and environmentally friendly. This special issue is in response to the increasing convergence between emerging and cloud computing architectures, while dierent approaches exist, challenges and opportunities are numerous in this context. The research papers selected for this special issue represent recent progresses in the eld, including works on heterogeneous computing architectures, energy-aware technology, elastic algorithms, virtual- ization and networking. This special issue includes ve extended version of the selected paper originally presented at the 4th IEEE International Conference on Cloud Computing Technology and Science (IEEE CloudCom 2012), held at Taipei, Taiwan. The papers selected for this issue not only contribute valuable insights and results but also have particular relevance to the emerging and cloud computing architectures. All of them present high quality results for tackling problems arising from the ever-growing cloud computing, heterogeneous computing as well as sustainable computing technologies. We believe that this special issue provides novel ideas and state-of-the-art techniques in the eld, and stimulates future research in the emerging and cloud computing community.
