Towards Liquid Service Oriented Architectures

The advent of Cloud computing platforms, and the growing pervasiveness of Multicore processor architectures have re-vealed the inadequateness of traditional programming mod-els based on sequential computations, opening up many chal-lenges for research on parallel programming models for build-ing distributed, service-oriented systems. More in detail, the dynamic nature of Cloud computing and its virtualized infrastructure pose new challenges in term of application design, deployment and dynamic reconfiguration. An appli-cation developed to be delivered as a service in the Cloud has to deal with poorly understood issues such as elasticity, infinite scalability and portability across heterogeneous vir-tualized environments. In this position paper we define the problem of providing a novel parallel programming model for building application services that can be transparently deployed on multicore and cloud execution environments. To this end, we introduce and motivate a research plan for the definition of a novel programming framework for Web service-based applications. Our vision called “Liquid Archi-tecture ” is based on a programming model inspired by core ideas tied to the REST architectural style coupled with a self-configuring runtime that allows transparent deployment of Web services on a broad range of heterogeneous platforms, from multicores to clouds
