This graphic has on the left the label "Client" bounded by a dotted line. It is connected by a line to a box labeled "Load Balancer," which points to a pentagon. That pentagon is the first in a column of three labeled "Web/Servlet Cluster." That first pentagon contains the labels "HTTP,""JSP," "Servlet" and Stub" The other pentagons contain the labels "HTTP,""JSP," and Servlet."
To the right of the Web/Servlet Cluster is another column of three pentagons labeled, "Object Cluster." Each pentagon contains the labels "EJB" and "JDBC."
The stub in the first pentagon in the first column points with three arrows to "EJB" in each of the pentagons in the second column. "JDBC" in each of the pentagons in the second column point to a database.
