Extending Grid Infrastructure Using Cloud Computing

Abstract

The computational domain is becoming huge and complex. Cloud computing has begun as a general computing model to support processing large volumetric data using clusters of commodity computers. In recent years, there is a need for extension of Grid Infrastructure to provide dedicated resources to the user. Cloud computing can fulfill resource requirements with the help of virtualization technology. By integrating the cloud computing with grid infrastructure, resource usage can be satisfied as per user demand. In this paper Globus toolkit is used as the grid middleware for the extension of the grid infrastructure using eucalyptus cloud environment. Virtual machines deployed at the Grid resource would satisfy the needs of the user application. Virtualization in the context of Grid can be implemented by combining the GT4 and Eucalyptus features. Globus tool kit, the middleware for Grid computing added the virtual machines via the Eucalyptus to extend the Grid computing environment to access the external Cloud environment. Grid computing community shows research interests in deploying computing systems or test beds with virtual machines. The extension of the GT4 grid middleware using Eucalyptus cloud environment will help the user to execute the jobs remotely with maximum utilization of the resources.
