Grid Middlewares: Interface Between Grid Resorces and Applications

Abstract

The Grid is computing and data management infrastructure, which provides the electronic underpinning for a global society in business, government and research. To realize the global grid environment we need a standard architecture to cope up the heterogeneity and the interoperatability among the various sites present in grid infrastructure. The grid architecture is realized using the various components like fabric, user and core level middlewares, applications and the portals. The middleware component is of extreme importance while building the Grid environment, as the majority of the Grid specific features are implemented using the Grid middleware. The grid middlewares act as glue between the grid resource components and the application components. They provide a high level of abstraction to the end users, hiding the underlying details. There exists a lot of implementation of these components in the market, each focusing on some different aspects. This thesis discusses these middlewares in detail. It elaborates how middlewares are realizing the architecture to create the grid environment. This creates a lot of confusion for the users to select a particular middleware for the grid setup or to be the part of the grid. In this thesis work, we have undertaken the problem to compare these middleware on the various factors so that it become easy for the end user to select the middleware to create a grid environment in which he can effectively and efficiently utilize the grid potential.
