Figure 1-21. Three-Tier LVS Topology
This topology is suited well for busy FTP servers, where accessible data is stored on a cen-
tral, highly available server and accessed by each real server via an exported NFS direc-
tory or Samba share. This topology is also recommended for websites that access a central,
high-availability database for transactions. Additionally, using an active-active configura-
tion with a Red Hat cluster, you can configure one high-availability cluster to serve both of
these roles simultaneously.
