17. A system comprising: means for receiving a properties file at a front-end layer of a configuration tool, the properties file having one or more properties to specify a configuration for a cluster of application server instances, the cluster having an application server architecture comprising at least one application server instance, each application server instance comprising a group of application servers configured with a redundant set of application logic and associated data, the cluster application server architecture further comprising a central database and a central services instance, the central database and central services instance being shared by the application server instances in the cluster, the central services instance having a locking service and a messaging service to facilitate communication and synchronization between each of the application servers in an application server instance being configured with a redundant set of application logic and associated data; means for storing the configuration for the cluster of application server instances in a data layer of the configuration tool, the data layer including the cluster's central database; means for displaying the configuration in the front-end layer of the configuration tool; means for generating a markup language file having one or more logical tasks, the one or more logical tasks based, at least in part, on the received properties; and means for passing the markup language file to a logic-layer of the configuration tool, the logic-layer to configure the cluster of application server instances in the data-layer of the configuration tool based, at least in part, on the one or more logical tasks of the markup language file.
17. A system comprising: means for receiving a properties file at a front-end layer of a configuration tool, the properties file having one or more properties to specify a configuration for a cluster of application server instances, the cluster having an application server architecture comprising at least one application server instance, each application server instance comprising a group of application servers configured with a redundant set of application logic and associated data, the cluster application server architecture further comprising a central database and a central services instance, the central database and central services instance being shared by the application server instances in the cluster, the central services instance having a locking service and a messaging service to facilitate communication and synchronization between each of the application servers in an application server instance being configured with a redundant set of application logic and associated data; means for storing the configuration for the cluster of application server instances in a data layer of the configuration tool, the data layer including the cluster's central database; means for displaying the configuration in the front-end layer of the configuration tool; means for generating a markup language file having one or more logical tasks, the one or more logical tasks based, at least in part, on the received properties; and means for passing the markup language file to a logic-layer of the configuration tool, the logic-layer to configure the cluster of application server instances in the data-layer of the configuration tool based, at least in part, on the one or more logical tasks of the markup language file. 18. The system of claim 17 , further comprising: means for executing the one or more logical tasks to configure the cluster of application server instances.
