Automating application updates in a virtual computing environment

In a computer-implemented method for automating application updates in a virtual computing environment, an update script and a digital signature for the update script are received, where the update script comprises an application update for updating an application installed on the virtual computing environment. The digital signature of the update script is validated using a public key of the virtual computing environment. Provided the digital signature of the update script is validated, the update script is executed to update the application.
