The Advanced Resource Connector (ARC) middleware introduced by NorduGrid is one of the leading Grid solutions used by scientists worldwide. Its simplicity, reliability and portability, matched by unparalleled efficiency, make it attractive for large-scale facilities like the Nordic DataGrid Facility (NDGF) and its Tier1 center, and also for smaller scale projects. Being well-proven in daily production use by a wide variety of sciences, ARC of today is still largely based on conventional Grid technologies introduced by Globus a decade ago. In order to guarantee sustainability, true cross-system portability, interoperability and standards-compliance, ARC community undertakes a massive effort of introducing Web Service based components into the middleware. With support from the EU KnowARC project, key ARC services are re-implemented in a service-oriented architecture, based on modern Grid standards. Such services include the resource-coupled execution service, the self-healing storage service and the peer-to-peer information system, to name a few. Gradual introduction of these new services and client tools into production middleware releases is carried out together with NDGF and thus ensures a smooth transition to the next generation Grid middleware. Standard interfaces and modularity of the new components design are essential for ARC contributions to the planned Universal Middleware Distribution by EGI. This talk will outline design principles of the new ARC services, update on the status of the middleware development, present the gradual transition process and lay out strategies for future ARC development and deployment.
