All refrences to claim(s) which appear below refer to the numbering after this setence.
1. A method for managing escalating resources needs of a job submitted in a grid environment, comprising:
enabling a grid environment comprising a plurality of computing systems each comprising at least one resource and communicatively connected over a network to share each said at least one resource through at least one grid service implemented within an open grid services architecture;
organizing, by a grid management system, said at least one resource into a hierarchy of discrete sets of resources comprising a plurality of local resources, a plurality of capacity on demand resources, and a plurality of external grid resources;
receiving a plurality of separate job requests from a plurality of client systems over said network at a grid management system;
submitting a particular job from among said plurality of jobs received at a said grid management system from a particular client system from among said plurality of client systems to a virtual organization comprising a first selection of said plurality of local resources from among said hierarchy of discrete sets of resources;
monitoring a performance level of said virtual organization handling said particular job;
comparing said performance level of said virtual organization with a performance requirement for said particular job;
responsive to a performance level of said virtual organization not meeting a required performance level for said particular job, querying said hierarchy of discrete sets of resources in an order designated by said hierarchy from among said second selection of capacity on demand resources and said third selection of external grid resources to meet said required performance level for said particular job; and
responsive to identifying at least one available additional resource from said hierarchy of discrete sets of resources, adding said at least one available additional resource to said virtual organization of said resources handling said particular job within said grid environment, such that escalating resource needs of said particular job in said grid environment are managed by hierarchically adding resources from discrete sets of resources within said grid environment to said virtual organization of said resources already handling said particular job.
2. The method according to claim 1 for managing escalating resource needs of a job submitted in a grid environment wherein submitting a particular job from among said plurality of jobs received at a said grid management system from a particular client system from among said plurality of client systems to a virtual organization comprising a first selection of said plurality of local resources from among said hierarchy of discrete sets of resources further comprises:
submitting said particular job to said virtual organization comprising said first selection of resources comprising at least one from among resources locally accessible to said particular client system initiating said job and resources accessible within an enterprise within which said particular client system operates.
3. The method according to claim 1 for managing escalating resource needs of a job submitted in a grid environment, wherein said hierarchy of discrete sets of resources is particularly specified for said particular job.
4. The method according to claim 1 for managing escalating resource needs of a job submitted in a grid environment, further comprising:
responsive to said performance level of said virtual organization of said first selection of resources not meeting said required performance level for said particular job, determining whether said particular job qualifies for additional resources; and
only querying said hierarchy of discrete sets of resources for available resources if said particular job qualifies for additional resources.
5. The method according to claim 1 for managing escalating resource needs of a job submitted in a grid environment, further comprising:
responsive to said performance level of said virtual organization of said first selection of resources not meeting said required performance level for said particular job, determining whether said particular job qualifies for at least one capacity on demand resource; and
responsive to said capacity on demand resource being identified as said at least one available additional resource from said hierarchy of discrete sets of resources, activating said capacity on demand resource by paying a fee in return for an electronic key which unlocks use of said capacity on demand resource.
6. The method according to claim 5 for managing escalating resource needs of a job submitted in a grid environment, further comprising:
deallocating said capacity on demand resource when not needed for said particular job.
