Client/server topology
In this topology, the engine tier, repository tier, and services tier are all installed on a single computer. The client tier is installed on separate computers.
The client tier computers must run Microsoft Windows. The computer that hosts the other tiers can run any operating system that IBM® InfoSphere® Information Server supports.
This topology centralizes administration and isolates it from client users. The following diagram illustrates this topology. Although the diagram shows only one client tier computer, you can include multiple client tier computers.
