Recently, the Grid middleware provides almost functions in the style of Web service including Globus Toolkit, GOS, etc. Right now, the new Web Services are deployed manually into the Grid middleware containers and become effective after the containers are restarted. However, it is necessary to deploy the Web Services dynamically on the Grid nodes since the states of Grid environment are changing over time, and simplify the difficulties of the Web Services' operations. Because of the particularity of the visualization' flow, it is a good way to adopt the Grid scientific workflow to implement the flow of the visualization. This paper presents an architecture to deploy visualization services dynamically and use the visualization services as the form of Grid scientific workflow. According to the experiment results, it is obvious that the service consumer can use the visualization services more conveniently, flexibly and efficiently.
