Deployment Model and Topology

Siebel Chat is deployed as a hosted (subscription model) application. In a Siebel Chat hosted deployment, Siebel Call Center is located on customer premises, but Oracle Contact On Demand is hosted elsewhere either by Oracle or an Oracle Partner in a single or multitenant fashion. In addition, the host service provider is responsible for providing all information that is required to set up and configure chat in a hosted style. For a hosted solution:

• Deploy agent users behind the firewall if supporting internal agent users only.
• Deploy agent users in Customer-Facing Applications (or Tier One) if supporting external agents over the Internet.
