Some embodiments of the invention provide a graphical user interface for receiving a server configuration (e.g., receiving a new configuration or a modification to an existing configuration). The graphical user interface (UI) includes several UI control elements for defining components of the server configuration. It also includes a display area for displaying graphical representations of the defined components of the server configuration. Examples of control elements in some embodiments include control elements for adding, deleting, and modifying servers. In some embodiments, at least one control element is displayed when a cursor control operation is performed on the UI. The cursor control operation (e.g., a right hand click operation) in some embodiments opens a display area that shows the control element. In some embodiments, at least two different components in the server configuration correspond to two different layers (e.g., a web server layer and a data storage layer) in the server configuration. The display area of some embodiments includes multiple tiers, where each tier is for displaying graphical representation of components in a particular layer of the server configuration. At least two tiers in some embodiments are displayed simultaneously in the display area.
