Ecosystem of Cloud Naming Systems: An Approach for the Management and Integration of Independent Cloud Name Spaces

Cloud computing is a highly dynamic environment where resources can be composed with other ones to provide many kinds of services to clients. In such scenario naming and resource location become critical issues and the existing Domain Name System (DNS), considered alone, is not able to address the new emerging problems. A cloud environment offers a variety of concrete and abstracted entities which need to be identified, whose states can frequently change: a virtual resource, could be allocated, deallocated or moved from a context to another. Moreover, a cloud entity could hold one or more names, identifiers, and representations in various cloud contexts where name alterations could frequently occur. In such environment, the management and integration of independent cloud name spaces is then becoming more compelling. This paper aims to propose a cloud naming system able to address such problems, providing an implementation practice in a cloud federation use case.
