1. A computer readable memory having stored thereon a multi-tiered management architecture for implementation by a computer, the management architecture comprising: an application development tier at which applications are developed for execution on one or more computers, the application development tier being implemented on a client console communicatively coupled to the one or more computers, wherein the client console is located remotely from a cluster operation tier console and an application operations tier console; an application operations tier at which execution of the applications is managed, the application operations tier being implemented on the application operation management console at a location remote from the oneor more computers; and a cluster operations tier to manage the operation of the computers without concern for what applications are executing on the one or more computers, wherein the cluster operations tier is responsible for securing a computer cluster boundary based on network filters received from the cluster operation tier console and the application operation management console giving precedence to those from the cluster operation tier console over the application operation management console to prevent a plurality of other computers that are not part of the computer cluster from accessing the one or more computers in the computer cluster.
