In developing any commercial system, it is essential to develop a scaled roadmap that allows validation of the service architecture in a lab or prototype phase, with a simple way to scale up to an initial commercial presence. Once this model is running, you can gradually meet increasing service loads, by separating functionality across computers, almost without limit. The following two-server configuration is quite capable of prototyping all of the functionality described here. A commercial deployment would separate functionality as described in a later chapter.
Hardware | Installed Software |
Gateway Server
| Windows 2000 with latest service pack Internet Security and Acceleration (ISA) Server |
Small Space Server
| Windows 2000 Server SP2 Internet Information Systems (IIS) 5.0 MSMQ SQL Server 2000 Exchange Server 2000 (if SMTP supported) |
A full capability configuration can be built from the following components:
Configuration | Installed Software |
Gateway Server Array (1-16 servers)
| Windows 2000 Server SP2 ISA Server Enterprise Edition Host Integration Server (opt) |
Transport Conversion Server Cluster (2-16 servers)
| Windows 2000 Advanced Server SP2 .NET Framework IIS 5.0 MSMQ Exchange Server 2000 |
Accounting Server (2-4 servers)
| Windows 2000 Advanced Server SQL Server 2000 .NET Framework Commerce Server 2000 (opt) |
Core Navigation Server (2-16 servers)
| Windows 2000 with latest service pack IIS 5.0 .NET Framework Host Integration Server (opt) |
Host Integration Server can be included if it is necessary to establish client-server connectivity with a mainframe system at the Gateway or for content integration at the Core Navigation server. These options are discussed in more detail in the next chapter.
