Overview

Grid

"Grids are persistent environments that enable software applications to integrate instruments, displays, computational and information resources that are managed by diverse organizations in widespread locations."

The Grid Problem?

The “Grid problem,” is a way of making flexible, secure, coordinated resource sharing among dynamic collections of individuals, institutions, and resources—what we refer to as virtual organizations. Read more on Grid

Need for an Open Architecture:

The Grid vision requires protocols (and interfaces and policies) that are not only open and general-purpose but also standard. It is standards that allow us to establish resource-sharing arrangements dynamically with any interested party and thus to create something more than a plethora of balkanized, incompatible, non-interoperable distributed systems. Standards are also important as a means of enabling general-purpose services and tools.

• OGSA: Open Grid Service Architecture

The Open Grid Services Architecture (OGSA) aims to define a new common and standard architecture for grid-based applications.

• OGSI: Open Grid Service Infrastructure

Building on both Grid and Web services technologies, the Open Grid Services Infrastructure (OGSI) defines mechanisms for creating, managing, and exchanging information among entities called Grid services. Specification for OGSA and OGSI

• GT3 Toolkit:

GT3 is a usable implementation of everything that is specified in OGSI (and, therefore, of everything that is defined in OGSA). http://www.globus.org
