Distributed computing has been applied to a variety of computational problems. Several software systems have been developed that make distributed applications available to an application programmer. Although these systems provide functionality for the design, execution, monitoring and control of distributed applications, they are not web-based The increasing use of Web technology for Internet and Intranet applications is making the web an attractive framework for solving distributed applications, in particular, because the interface can be made platform independent. This paper presents a web-based environment which provides remote management of distributed applications. The environment allows the user to con.gure, execute, monitor and dynamically reconfigure distributed components. In addition the tool tolerates node failures to ensure service availability, and can be tailored to different distributed application platforms. The proposed tool is developed without changing the front-end web server and does not require manual software installation on the client side as long as a client web browser is available.
