Abstract

A patching module being executed by a computing device may select a node comprising a first set of instances of a first module, a second set of instances of a second module, and infrastructure software used by the first and second set of instances. The patching module may apply an infrastructure patch to a copy of the infrastructure software to create patched infrastructure. The patching module may stop the first and second set of instances using the infrastructure software and restart the first and second set of instances to use the patched infrastructure. The patching module may determine that a module patch applies to the first module, copy the first module, and apply the module patch to the copy to create a patched module. The patching module may stop the first set of instances of the first module and start a third set of instances of the patched module.
