This article describes how to plan for administration sites in an Enterprise Project Management (EPM)/ Microsoft Office SharePoint Server 2007 extranet environment. For an overview of this chapter about how to plan for EPM extranets, see Plan an EPM/Office SharePoint Server 2007 extranet environment.

Administration sites

In the model, each administration site is hosted inside a dedicated application pool and Web application. The following list describes each administration Web site:

  • Shared services administration Web sites   The model shows a dedicated administration site for each SSP. Shared services administration sites cannot be isolated on a single server or set of servers. These sites are automatically mirrored across all front-end Web servers.

  • Central Administration Web sites   In the model, the SharePoint Central Administration Web site for each server farm is hosted on an application server. This protects the site from direct user contact. If a performance bottleneck or security compromise affects the availability of the front-end Web servers, the Central Administration site remains available.

The load-balanced URLs for administration sites are not articulated in the model or in this article. Recommendations include the following:

  • If port numbers are used in administrative URLs, use non-standard ports. By default, port numbers are included in URLs. Although port numbers are typically not used in customer-facing URLs, using port numbers for administration sites can increase security by limiting access to these sites to non-standard ports.

  • Allow access to administration sites only from an administrative domain.

  • Create separate DNS entries for administration sites.

In addition to following these recommendations, you have the option to load-balance the Central Administration site across multiple application servers to achieve redundancy.
