14. The one or more memories of claim 13 , wherein the acts further comprise marking at least one of the one or more configuration items as optional or mandatory, and wherein setting the deployment configuration comprises determining for each of the one or more configuration items whether the configuration item is marked as mandatory, and if the configuration item is marked as mandatory, then a user input is required for that configuration item before deploying the virtual application package.

15. The one or more memories of claim 11 , wherein:

the deployment configuration is a first deployment configuration;

deploying the virtual application package to instantiate the software application comprises deploying the virtual application package to instantiate the software application in a first instance of the software application;
