CA ITCM has two management tiers, the domain and the enterprise, with management databases being present at both tiers. In situations where multiple domains are deployed within an organization, an enterprise can be deployed to provide a single point of management.
The following illustration shows an example of a two-tier architecture consisting of the company's enterprise manager and two domain managers, which have two scalability servers connected to each of them:
The enterprise manager, called duck.com, and two domain managers, one for managing tasks and devices in the North-America area (northamerica.duck.com) and the other for managing tasks and devices in the Europe area (europe.duck.com). Two scalability servers are connected to each of the domain managers to reduce the workload of the domain managers by managing end user devices such as laptops and workstations and further servers.
