Cloud to cloud interoperability

Cloud computing describes a new distributed computing paradigm that allows system of systems to access a shared pool of configurable computing resources (e.g., networks, servers, storage, data, applications, and services) that can be rapidly provisioned and released over the Internet with minimal user-management effort or cloud-provider interaction. Interoperability is central to enabling sharing of resources from a pool of cloud-service providers in a seamless fashion. In this paper we describe some of the challenges in achieving interoperability for cloud computing and recommend an adaptation of the U.S. Department of Defense's LISI Maturity Model to address cloud-to-cloud interoperability.
