Logical architecture is the manner in which logical components of a solution are organized and integrated. In Microsoft Office SharePoint Server 2007, the logical components include Shared Services Providers (SSPs), Internet Information Services (IIS) application pools, Web applications, zones, policy for Web applications, content databases, site collections, sites, host-named site collections, and My Sites.

In this chapter:

• Logical architecture components introduces each of the logical architecture components and discusses the following considerations for each component: capacity, sharing and isolation, configurable items, administration, and planning recommendations.

• Logical architecture model: Corporate deployment describes a practical implementation of logical architecture components to achieve a workable design, including the configuration of users, authentication, and administration sites. The accompanying model illustrates a design example of a corporate deployment of Office SharePoint Server 2007. The model illustrates how the components of the logical architecture are incorporated into the overall design. This article describes the design goals for the model and explains how the goals are achieved using the logical architecture components illustrated in the model.

• Plan alternate access mappings (Office SharePoint Server) provides information about configuring Office SharePoint Server 2007 to map Web requests to the correct Web applications and sites. It describes how to implement alternate access mappings for common Internet deployment scenarios in which a Web application that receives a request for an internal URL, in one of the five authentication zones, returns pages that contain links to the public URL for the zone.

• Update a Web application URL and IIS bindings (Office SharePoint Server) provides guidance for changing the URL and IIS bindings of a Web application.

• Design an intranet solution architecture:

  • Design logical architecture for collaboration sites provides logical architecture design recommendations for deploying team sites within a server farm.

  • Design My Sites architecture provides logical architecture design recommendations for deploying My Sites within a server-farm.

• Design Records Center architecture provides recommendations that can help you configure and organize the logical components of a records management solution based on Office SharePoint Server 2007 and provides guidance for configuring key features of your records management solution.
