Grid computing can benefit from the improvement of cloud computing by deploying it on (grid-enabled resources). The usage of virtualization technology on cloud will improve the management and reliability of those resources. The aim of this paper is to study the benefit of applying cloud computing, by adding a service manager in grid infrastructures. This device should be able to help bearing the demand requests from distributed services and pass it to external partner (cloud), exploiting the benefit concept of pay-per-use and the powerful storage facility which exist on cloud computing technology. This will improve the quality of service (QoS) or meet the request of peak demands within the grid environment. This paper identifies the relevant work, and specified the problem that should be solved. Eventually, an architecture includes the device manager is proposed. © 2012 IEEE.
