A data structure called a product version map is introduced. The product version map contains a catalog of available application versions to be used by the application orchestration services. It can describe the available versions. For each version, there is an image, such as a Docker® container image, that can be used to instantiate the application instance. Furthermore, in some example embodiments, an expiration date can be given, which could be used to enforce upgrades of application instances when their used version expires.
