A re-stacking and security vulnerability data display is generated that includes individual graphic representations of instances (virtual computing systems) used to provide a software application in a cloud computing environment. The re-stacking and security vulnerability data display shows a launch date for each instance, a termination date for the instance, an indication of an instance vulnerability score assigned to the instance, and the base instance creation template release dates for each of the base instance creation templates. Consequently, the re-stacking policy and security vulnerabilities associated with that re-stacking policy for an account can be readily determined by a simple examination of the re-stacking and security vulnerability data display. As a result, any potential security issues and vulnerabilities can be readily identified and addressed.
