A cloud service computing system can provide a runtime snapshot for an application in response to a request from a client computing system for the application. A cloud service computing system executes the application to an execution state and creates a snapshot that includes information indicating the application objects created by the application during execution of the application and the state of the application objects at the execution state. The snapshot further includes bytecode for the application and may also include configuration settings for the runtime under which the application was executed by the cloud service computing system to generate the snapshot. The client computing system can place the application in a ready to service state by initializing a managed heap with the bytecode and the heap objects based on information contained in the snapshot and placing the heap objects into a state indicated by information contained in the snapshot.
