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.
