Semantic and Agnostic Representation of Cloud Patterns for Cloud Interoperability and Portability

This paper focuses on two aspects related to the widespread of cloud computing: first, the definition of a common formalism, based on a unique and shared model, which could be used to completely describe Cloud patterns; second, the investigation of a methodology to automatize the recognition of similar elements in Design and Cloud patterns, thus defining an automatic mapping among representations of application that follow these patterns. These aspects are handled on one hand by extending an existing semantic based Design pattern language in order to properly represent both Design and Cloud patterns together with its possible related architectural implementations and on the other hand by using these agnostic representations to define a mapping between Design patterns ( a single design pattern or a composition of pattern) and Cloud patterns, in order to obtain a clear model of the cloud applications which could satisfy its original requirements and exploit all the benefits of cloud computing at the same time.
