As described, this configuration uses the components for a heavy load system. If you expect a light load on the network, you might consider installing the WebSpeed Transaction Server and OpenEdge Workgroup RDBMS instead of the Enterprise Transaction Server and OpenEdge Enterprise RDBMS. The WebSpeed Transaction Server can handle up to 50 WebSpeed Agents. The OpenEdge Workgroup RDBMS can handle up to 65 connections.

You can expand the capacity of either side of this configuration by adding new server machines with the same products installed. Register the WebSpeed Transaction Servers on the new machines with the NameServer that is handling the Transaction Servers for that side.

When you expect heavy loads on your network or want to increase its fault tolerance, you might want to add the load balancing option for the NameServer. If you deploy several WebSpeed Transaction Servers that support the same application service, you can use load balancing to control how the load is spread over them. See Understanding the NameServer's load balancing option for additional information.

If you are going to use a non-OpenEdge database, you must install the appropriate DataServer on the Nereid and Proteus servers.
