Abstract: A system, method, and apparatus for providing continuous operations of a user e-mail application at a user computing device. At least two application servers, such as e-mail servers, are provided with each application server running the user e-mail application concurrently and independently. Each application server may have a persistent storage device associated with it for storing data. In response to a user request for data processing within the user application, the user request is transmitted to the at least two application servers for processing therein. A return result—responsive to the user request as processed by the one of the at least two application servers—is passed to the user computing device from one of the at least two application servers. In this manner, if one of the application servers fails or becomes unavailable due to a disaster or otherwise, the user e-mail requests can be continuously processed by at least the other application server without any delays.
