This graphic has on the left the label "Clients" bounded by a dotted line. It is connected to "Load Balancer" by a line, which points to a box. This box is the first in a column of three labeled "Web/Servlet Cluster". The first box contains the labels "HTTP", "JSP", "Servlet", and "Stub". The other boxes contain the labels "HTTP", "JSP", and "Servlet".

To the right of the Web/Servlet Cluster is another column of three boxes labeled "Object Cluster". Each box contains the labels "EJB" and "JDBC".

The stub in the first box of the Web/Servlet Cluster points "EJB" in each of the boxes in the Object Cluster with arrows. "JDBC" in each of the boxes in the Object Cluster point to a Database.
