Semantic Techniques for Multi-Cloud Applications Portability and Interoperability

The composition of Cloud Services to satisfy customer requirements is a complex task, owing to the huge number of services that arecurrentlyavailable. TheadventofBigDataandInternetofThings(IoT),whichrelyonCloudresourcesforbetterperformances and scalability, is pushing researchers to find new solutions to the Cloud Services composition problem. In this paper a semanticbased representation of Application Patterns and Cloud Services is presented, with an example of its use in a typical distributed application, which shows how the proposed approach can be successfully employed for the discovery and composition of Cloud Services..
