An information processing system includes a preparation machine with an installed image; an execution machine on which the installed image is virtually installed; and a virtualizer for virtualizing the installed image on the execution machine to produce a virtually installed image by using a hierarchy of selective virtualizers, wherein the virtualizing is selective such that not all operations of the executing software of the installed image at any particular level are virtualized.

Simplifying the deployment and serviceability of commercial software environments

A method for executing on a first computer an application having an installed image prepared on a second computer, wherein the installed image is virtually installed on the first computer, is disclosed. The method includes emulating on the first computer a native environment of the second computer. The method further includes detecting an operation of the application upon data, wherein the operation requires an operation on data located on the first computer, and wherein a copy of the data is located in the virtually installed image. The method further includes directing the operation of the application to operate on the data located in the virtually installed image.
