Method, system, apparatus, and computer program and computer program product provide on-demand, scalable computational resources to application providers over a distributed network and system. Resources are made available based on demand for applications. Application providers are charged fees based on the amount of resources utilized to satisfy the needs of the application. In providing compute resources, method and apparatus is capable of rapidly activating a plurality of instances of the applications as demand increases and to halt instances as demand drops. Application providers are charged based on metered amount of computational resources utilized in processing their applications. Application providers access the network to distribute applications onto network to utilize distributed compute resources for processing of the applications. Application providers are further capable of monitoring, updating and replacing distributed applications. Apparatus and system includes plurality of computing resources distributed across a network capable of restoring and snapshotting provisioned applications based on demand.

The present invention provides virtual mapping of system resource identifiers in use by a software application for the purpose of making the running state of an application node independent. By adding a layer of indirection between the application and the resource, new system resources are reallocated and then can be mapped to the application's existing resource requirements while it is running, without the application detecting a failure or change in resource handles. This layer of indirection makes the application's system resource identifier(system RID) transparent to the application. RID's are usually numeric in form, but can also be alphanumeric. RID's are unique to a machine, and can be reused once all claims to a specfic RID have been given up.

A system, methods, and computer program products are disclosed for creating virtual application templates for the purpose of propagating a single application snapshot into multiple, distinct images. Snapshot virtual templates allow multiple application instances to use the same fixed resource identifier by making the resource identifier virtual, privatizing it, and dynamically mapping it to a unique system resource identifier. When a snapshot is cloned from a virtual template, the common or shared data is used exactly as is, whereas the non-sharable data is either copied-on-write, multiplexed, virtualized, or customized-on-duplication. The present invention notes access to modified resources, fixed system IDs/keys and unique process-related identifies and automatically inserts a level of abstraction between these resources and the application. The resources contained in a snapshot virtual template can be dynamically redirected at restore time. Access to memory and storage is managed in a copy-on-write fashion. System resource handles are managed in a virtualize-on-allocate fashion or by a multiplex-on-access mechanism. Process-unique resources are managed in a redirect-on-duplicate fashion. Rules may be defined through an application configurator that allows some degree of control over the creation of non-sharable data. The snapshot virtual template is constructed by dividing the snapshot image into sharable and non-sharable data. Knowledge of which system resources can be shared is encoded in the application snapshot/restore framework.
