Next Generation Clouds, the Chameleon Cloud Testbed, and Software Defined Networking (SDN)

Abstract

Next generation clouds, based on highly programmable, high performance networks, especially those supported by Software-Defined-Networking (SDN) have attracted significant interest by research communities. In recognition of the increasing importance of advancing cloud services and technologies, especially for providing Internet services, the US National Science Foundation (NSF) established a project, the NSF Cloud initiative, to enable the computer science research community to develop and experiment with novel cloud architectures and create new, architecturally enabled innovative applications for cloud computing through empirical research experimentation by using large scale distributed cloud test beds. This paper provides an overview of one of those test beds, the Chameleon Cloud tested, with an additional description of the integration of that test bed with high programmable, high performance networks, based on SDN. The Chameleon project is designing, deploying, and operating a large scale, highly distributed experimental environment for empirical cloud research, integrated with high programmable networks as a foundation resource.
