Description
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.
