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.
