The OASIS TOSCA specification [OAS13b] aims at enhancing the portability and interoperability of cloud-based applications by providing a language to describe and manage them across heterogeneous clouds. A cloud-based application is modelled by a service template, an orchestration of typed nodes which can be in turn instantiated by matching [BS13] other service templates. In this paper we present a methodology to non-intrusively adapt a service template S into a new service template newS which exactly matches a node type N, and hence to easily reuse any actual service modelled by S to deploy cloud-based applications that rely on N.

Abstract
The OASIS TOSCA specification [OAS13b] aims at enhancing the portability and interoperability of cloud-based applications by providing a language to describe and manage them across heterogeneous clouds. A cloud-based application is modelled by a service template, an orchestration of typed nodes which can be in turn instantiated by matching [BS13] other service templates. In this paper we present a methodology to non-intrusively adapt a service template S into a new service template newS which exactly matches a node type N, and hence to easily reuse any actual service modelled by S to deploy cloud-based applications that rely on N.File in questo prodotto:
