<strong>Exceed</strong> <strong>onDemand</strong> 5 — A <strong>Technical</strong> <strong>Whitepaper</strong><br />
Cluster configuration — multiple <strong>Exceed</strong> <strong>onDemand</strong> Servers are programmatically linked together<br />
to form a large, single, logical computing unit. Each <strong>Exceed</strong> <strong>onDemand</strong> Server within a Cluster<br />
is called node.<br />

<strong>Exceed</strong> <strong>onDemand</strong> Server can be further divided into three major components: <strong>Exceed</strong> <strong>onDemand</strong><br />
Cluster Manager, X Proxy Manager and <strong>Exceed</strong> <strong>onDemand</strong> Proxy.<br />
<strong>Exceed</strong> <strong>onDemand</strong> Cluster Manager<br />
<strong>Exceed</strong> <strong>onDemand</strong> Cluster Manager is the top of the chain of command, and it is physically present<br />
in every installation of <strong>Exceed</strong> <strong>onDemand</strong> Server. It has the following tasks: auth/enticate users,<br />
govern license usage, manage all X Proxy Managers (see below), manage all types of configuration<br />
files, balance work load (in a cluster configuration) and keep track of shared and suspended sessions.<br />
Every Server or Server Cluster can only have ONE Cluster Manager. The role of <strong>Exceed</strong> <strong>onDemand</strong><br />
Cluster Manager is consistent in both Standalone and Cluster configurations.<br />
