<title>Balancing Workload Across Servers</title>
<para>One main reason for deploying a directory proxy server is to balance
workload across the directory servers available. Load balancing works
particularly well for read operations, as each directory server can respond
to read operations without impact on other directory servers. Load balancing
can also be used in reverse for write operations, as in a replicated
environment the results of each write operation must be applied on all
directory servers to keep their data in sync.</para>
<para>This chapter demonstrates how to configure proxy load balancing of
client application traffic.</para>
