1. A method for dynamically creating a high availability policy based upon entries in a configuration management database (CMDB) and a best practices template, the method comprising: displaying in a computer, a user interface through which an application is selected for high availability configuration; directing resource discovery in a CMDB for the selected application to discover components and dependencies of the selected application, the resource discovery processing different configuration items (CIs) in the CMDB in order to identify the components and dependencies of the selected application; selecting a best practices template from amongst other templates in a data store, the best practices template comprising a structured markup language document with different entries of the document specifying a parameterized high availability topology for the selected application that has been proven as a topology of a known arrangement of components of another application in order to deploy a highly available form of the other application including an arrangement directed to a concurrent execution of processes, an arrangement directed to an available network address and a file system mount point that must be available for a component of the other application to properly function; mapping the components and dependencies discovered for the selected application in the CMDB to the best practices template; and, storing the best practices template with mapped components and dependencies as a high availability policy for the selected application, the policy comprising parameterized entries of the template replaced with specific entries particular to the selected application, including a network address and file system mount point to be used when deploying the high availability policy.
