Each resource is capable of being configured by multiple elements that provide a different configuration of the resource. Service information is maintained indicating at least one performance and availability attribute of the configuration of the resource by the element. At least one administrator specified performance and availability attribute for a configuration is received. A determination is made of at least one element for each resource having service information indicating at least one performance and availability attribute that satisfies the at least one administrator specified performance and availability attribute.
