The document discusses the idea of an Inter-Cloud eXchange (ICX) to facilitate interoperability and neutrality between clouds, similar to how Internet exchanges (IXs) enable interconnection and peering between networks on the Internet. It frames key issues such as the role of IXs in cloud environments, the extent to which Internet peering is similar to cloud peering, and standards and flexibility needed for ICX. Diagrams show how an ICX ecosystem could operate as a common platform for clouds to communicate, trade, and share virtualized resources via common APIs, analogous to how IXs facilitate Internet peering.
