Intercloud Exchanges and Roots Topology and Trust Blueprint

摘要

Cloud computing is a new design pattern for large, distributed datacenters. Initially, Service providers offering included cloud enabled productivity applications such as search, email, and social networks. Recently they have expanded their offerings to include compute-related capabilities such as virtual machines, storage, and complete operating system services. The cloud computing design yields breakthroughs in geographical distribution, resource utilization efficiency, and infrastructure automation. These "public clouds" have been replicated by IT vendors for corporations to build "private clouds" of their own. Public and private clouds offer their end consumers a "pay as you go " model - a powerful shift for computing, towards a utility model like the electricity system, the telephone system, or more recently the Internet. However, unlike those utilities, clouds cannot yet federate and interoperate. Such federation is called the "Intercloud". Working groups have proposed a layered set of protocols called "Intercloud Protocols " to solve this interoperability challenges. Instead of each cloud provider establishing connectivity with another in a Point-to-Point manner resulting into an n2 complexity problem, Intercloud interoperability embodies 1-to-many and many-to-many models as opposed to mere cloud to cloud. This paper is in continuation and subsequently builds on to our earlier "Intercloud" related work. The paper proposes the overall design of decentralized, scalable, self-organizing federated "Intercloud" topology by specifically delving deep into how each "Intercloud" component fits in within the overall topology and how these components interact with each other.
