Two Ways to Grid: The Contribution of Open Grid Services Architecture (OGSA) Mechanisms to Service-Centric and Resource-Centric Lifecycles |

Service Oriented Architectures (SOAs) support service lifecycle tasks, including Development, Deployment, Discovery and Use.
We observe that there are two disparate ways to use Grid SOAs such as the Open Grid Services Architecture (OGSA) as exemplified
in the Globus Toolkit (GT3/4). One is a traditional enterprise SOA use where end-user services are developed, deployed and
resourced behind firewalls, for use by external consumers: a service-centric (or ‘first-order’) approach. The other supports
end-user development, deployment, and resourcing of applications across organizations via the use of execution and resource
management services: A Resource-centric (or ‘second-order’) approach. We analyze and compare the two approaches using a combination
of empirical experiments and an architectural evaluation methodology (scenario, mechanism, and quality attributes) to reveal
common and distinct strengths and weaknesses. The impact of potential improvements (which are likely to be manifested by GT4)
is estimated, and opportunities for alternative architectures and technologies explored. We conclude by investigating if the
two approaches can be converged or combined, and if they are compatible on shared resources. |
