Multi Cloud Architecture is an emerging technology in cloud computing to improve the security of data and process management in single clouds. Dynamic Resource Allocation is a proven technique for efficient Resource Management in Single Cloud Architecture to mitigate resource overflow and underflow problems. Resource Management in Single Cloud Architecture is an improving area and still it has to address many problems of resource management like resource bottlenecks. Resource Management at

... e cloud always recommends the additional resources adoption due to frequent resource underflow problems. In this paper we proposed a Resource Grid Architecture for Multi Cloud Environment to allocate and manage the resources dynamically in virtual manner. This architecture introduces a resource management layer with logical resource grid and uses the virtual machines to map the resources against physical systems of single cloud. Experiments are proving that our Resource Grid Architecture is an efficient architecture to manage the resources against multiple clouds and supports the green computing.
