Software accesses a code database and determines that a specified percentage of the code in the code database for an application has been updated. The software then accesses an application database and obtains the application as currently deployed. The software obtains one or more application specifications from the application database, based at least in part on a scan of the application. And the software obtains one or more code-module specifications from the code database, based at least in part on the one or more application specifications. The software then determines that an update can be made to the application as currently deployed, based at least in part on code-module dependencies identified in the one or more application specifications and updated code modules for the application in the code database. And the software creates a new version of the application using the updated code modules and deploys the new version.
