A method for modeling a computing architecture is provided. Computing layers of the computing architecture are identified, wherein each computing layer represents a functional layer of the computing architecture. Computing systems of the computing system are identified. Computing layers implemented by the computing system are identified. Stacked bars are displayed to represent the computing layers. Second bars orthogonal to the stacked bars are displayed to represent the computing systems, wherein each second bar extends through a portion of the stacked bars an amount corresponding to the computing layers implemented by the computing system represented by the second bar.
