SRA includes other Java technology processes called Netlet Proxy and
Rewriter Proxy. You use these proxies to extend the security perimeter from
behind the firewall, and limit the number of holes in the DMZ. You can install
these proxies on separate nodes.
Working with Portal Server Building Modules
Because deploying Portal Server is a complex process involving many other
systems, this section describes a specific configuration that provides optimum
performance and horizontal scalability. This configuration is known as a Portal
Server building module.
A Portal Server building module is a hardware and software construct with limited
or no dependencies on shared services. A typical deployment uses multiple
building modules to achieve optimum performance and horizontal scalability.
Figure 5-2
shows the building module architecture.

Portal Server Building Module Architecture
NOTE
The Portal Server building module is simply a recommended
configuration. In some cases, a different configuration might result
in slightly better throughput (usually at the cost of added
complexity). For example, adding another instance of Portal Server
to a four CPU system might result in up to ten percent additional
throughput, at the cost of requiring a load balancer even when using
just a single system.
