As a result of Internet popularly, the World Wide Web, a killer application which improves the global network, is used much more frequently. Because World Wide Web is browsed through GUI (Graphic User Interface) which allows end-user to interact and operate with internet websites easily, more and more websites are created and operating. For this moment, the web based GUI proved its advantages that it can be applied not only to general website but also to electronic commerce, enterprise information system, and system resources administration. Today, the processing architecture evolves from early centralized processing architecture to recently distributed processing architecture which is composed of several servers and in which each server is responsible for a different system service. But because each system platform runs on its own unique operating system, system administrators have difficulties operating it. Due to increased numbers of servers, a well-defined systematic management architecture and remote management is necessary. This thesis contains the designs of web based system administration architecture through the designs of united library interface to increase the convenience of expansion on library. In this paper, a prototype system created during the research development will serve as theory verification and as an example for developers of future system management platforms.
