We Utilize Microsoft recommended 3-Tier deployment model. Presentation Tier. The presentation tier receives all incoming client requests from the Internet. This tier contains your Commerce Server 2002 Solution site, which runs on a Microsoft Internet Information Services (IIS) Web server. This tier also includes a Windows 2000 domain controller, as well as an ISA server, which is used as a firewall to protect the presentation tier from the Internet.

Data Tier. Two SQL Server 2000 servers host the Commerce Server 2002 run-time databases and the Commerce Server Data Warehouse respectively. The the first server runs Microsoft Commerce Server 2002 and the Business Desk application. Again there's a Windows 2000 domain controller, as well as an ISA server, which is used as a second firewall to protect the data tier from the presentation tier.

Corporate LAN Tier. The Corporate LAN tier is used for accessing Commerce Server 2002 Business Desk. A third ISA server is used as a firewall to protect the data tier from the Corporate LAN tier.
