Software patch application and testing optimization

Abstract:

One or more computer processors receive a patch request containing a testing requirement for a target platform. The one or more computer processors create a plurality of clusters containing a plurality of previously patched platforms associated with the target platform. The one or more computer processors calculate a similarity index of previously patched platforms and the target platform utilizing the created plurality of clusters, wherein the similarity index represents a similarity between the target platform and the plurality of patched platforms. The one or more computer processors adjust the testing requirement utilizing one or more similar platforms that are determined by the calculated similarity index and associated testing requirements. The one or more computer processors execute the requested patch utilizing the adjusted testing requirement.
