A method of defining and deploying a networked computer system, comprising the steps of: creating and storing a graphical representation of a logical configuration of the networked computer system by generating a display of a graphical workspace that can receive the graphical representation; receiving user input representing selecting one or more icons that represent nodes of the networked computer system and moving the one or more icons into the graphical workspace; receiving user input representing connecting one or more of the icons with one or more other icons; receiving user input representing configuring one or more parameter values associated with one or more of the nodes; instantiating an operable computer system that conforms to the logical configuration.
