Computing Grid in this paper is a Grid computing environment that supplies applications which run in a local computing site only, without any modification or adaptation for running globally in the Grid computing environment. Each stage of a running application is transcribed at all the management databases coupled with respective Web servers. The consistency is maintained by double-checking of every acknowledgement against a write to all the management databases and a circulated read response from either database. The storage spaces could be integrated into a single one by storage managers within a computing site. The modification of a file is broadcast to the storage managers sharing the storage space and their allocation tables are updated immediately. The system architecture is in a distributed control type, potentially the best match for Cloud computing.
