1. A computer implemented method for automatically creating application service level representations of applications executing on a cluster and being made highly available, based on cluster level operational representations of the applications and their associated resources, the method comprising the steps of: maintaining, by a computer, a repository of multiple application service templates, wherein each application service template defines attributes of an application type to include in corresponding application service level representations, and information defining how the attributes of the application service template are to be populated with values to represent a specific instance of an application of the application type at a service level; for a specific instance of an application executing on the cluster and being made highly available, selecting, by the computer, an application service template from the repository to use to create a corresponding application service level representation; populating, by the computer, the attributes of a copy of the selected application service template with values describing the specific instance of the application and its associated resources, thereby automatically creating a service level representation of the specific instance of the application, wherein the populating the attributes further comprises assigning a value to a service identifier which can be used to access and reference the specific instance of the application at the service level; validating, by the computer, the values used to populate the attributes of the service level representation created for the specific instance of the application; and publishing, by the computer, the service level representation created for the specific instance of the application to an application service consumer for which the application is being made highly available, wherein the application service consumer can access the specific instance of the application executing on the cluster at the service level through the service identifier.
