Description
The aim of the EGEE (Enabling Grids for E-Science in Europe) is to
create a reliable and dependable European Grid infrastructure for
e-Science. The objective of the Middleware Re-engineering and Integration
Research Activity is to provide robust middleware components,
deployable on several platforms and operating systems, corresponding
to the core Grid services for resource access, data management,
information collection, authentication & authorization, resource
matchmaking and brokering, and monitoring and accounting.
For achieving this objective, we developed an architecture and
design of the next generation Grid middleware leveraging experiences
and existing components mainly from AliEn, EDG, and VDT. The
architecture follows the service breakdown developed by the LCG ARDA
RTAG. Our goal is to do as little original development as possible but
rather re-engineer and harden existing Grid services. The evolution of
these middleware components towards a Service Oriented Architecture
(SOA) adopting existing standards (and following emerging ones) as
much as possible is another major goal of our activity.
A rapid prototyping approach has been adopted, providing a sequence of
more sophisticated prototypes to the EGEE candidate applications
coming from the LHC HEP experiments and the Biomedical field. The
close feedback loop with applications via these prototypes in
indispensible for achieving our ultimate goals of providing a reliable
and dependable Grid infrastructure.
In this paper we will report on the architecture and design of the
main Grid components and report on our experiences with early
prototype systems.
