Enabling Declarative Service Composition for Cloud Application

Abstract

Cloud applications provides users with services that can be accessed on demand through the Internet. Fertile service frameworks are considered as one of the most critical ingredients for the envisaged benefits so as to further interactions among cloud computing resources and application components. Such foundations should lead to the proliferation of new innovative services and applications. Research community has been exploring OSGi’s potential as a top candidate for cloud application platforms. Although the current OSGi specification provides some level of support for dynamic service discovery, tracking, and composition, more should be done to be able to adequately address the need for diverse interaction patterns for cloud applications. This paper introduces a novel service framework built upon OSGi platforms that supports a directed-acyclic-graph style composition of constituent services.
