Reducing costs for a distribution of applications executing in a multiple platform system

摘要

Embodiments of the claimed subject matter are directed to methods and a system that allows the reduction of costs attributed to executing applications on a multi-platform system (such as a mainframe) by migrating certain processes operating on one platform to another platform in the system. In one embodiment, the reduction of cost is achieved by a method for migrating an application executing in a partition operating a proprietary operating system to a second partition operating an alternate operating system and leveraging special purpose processors unavailable to the proprietary operating system, which can be much less costly to purchase and/or rent and license.

1. A computer-implemented method comprising:
executing a first instance of a particular application in a proprietary operating system hosted in a first partition on a particular server, then commencing processing of a particular transaction by the first instance of the particular application, the proprietary operating system being proprietary to a type of the server, and wherein processing the particular transaction by the first instance of the particular application comprises generating computer instructions for processing by one or more central processors of the particular server that are configured to process computer instructions associated with the proprietary operating system; (i) after the particular transaction has commenced processing by the first instance of the particular application and (ii) before the particular transaction has completed processing by the first instance of the particular application, executing a second instance of the particular application in a dissimilar, non-proprietary operating system hosted in a second partition on the particular server, then commencing processing of the particular transaction by the second instance of the particular application, wherein processing of the particular transaction by the second instance of the particular application comprises generating computer instructions for processing by one or more special purpose processors of the server that are not configured to process computer instructions associated with the proprietary operating system; and (i) before the particular transaction has completed processing by either the first instance of the particular application or the second instance of the particular application that is executing in the non-proprietary operating system, and (ii) when processing of the particular transaction by the first instance of the particular application reaches a same stage as the processing of the particular transaction by the second instance of the particular application, transferring primary operation of the particular transaction from the first instance of the particular application executing in the proprietary operating system to the second instance of the particular application executing in the non-proprietary operating system, then terminating processing of the particular transaction by the first instance of the particular application.
