Cloud Network Infrastructure as a Service : An Exercise in Multi-Domain

Cloud computing is now a successful and wellunderstood example of the Infrastructure as a Service (IaaS) model. This paper explores how to extend IaaS clouds to other kinds of substrate resources beyond servers and storage, and to link these elements together in a coordinated, multi-provider “web” of cloud infrastructure services. The vision is to enable cloud applications to request virtual servers at multiple points in the network, together with bandwidth-provisioned network pipes and other network resources to interconnect them. We outline new software to orchestrate end-to-end connections over multi-layer networks, coordinated with Eucalyptus clouds and other resources at the edge. We present results from a demonstration experiment with the prototype, and discuss various architectural challenges arising in multi-domain cloud computing with dynamic circuit networks.
