Understanding Office SharePoint Server 2007 deployment topologies with IAG

Applies To: Intelligent Application Gateway (IAG)

This topic describes some of the commonly used topologies for deploying servers running SharePoint Products and Technologies through Whale Communication Intelligent Application Gateway (IAG) 2007, including the following information for each topology:

  • Relationships between servers running SharePoint Products and Technologies and IAG

  • Relationship between the SharePoint site's internal address, which is used to access the site from within the organization, and public address, which is the public-facing address that is used to access the site remotely

Publishing topologies that are discussed in this topic include the following:

  • Publishing a SharePoint Web application

  • Publishing multiple SharePoint Web applications

  • Publishing multiple SharePoint Web applications on a single port

  • Publishing a SharePoint Web application when using identical internal and public addresses

  • Publishing a single SharePoint Web application via multiple IAG trunks

Publishing a SharePoint Web application

The most basic, common topology consists of the following:

  • A server running SharePoint Products and Technologies publishes a single Web application.

  • The SharePoint Web application is published via only one IAG trunk.

  • The public address of the SharePoint site is different than the internal address of the site.

  • External users access the SharePoint site over HTTPS; internal users access the same site over HTTP.

Publishing multiple SharePoint Web applications

A topology that publishes multiple SharePoint Web applications on separate ports consists of the following:

  • A server running SharePoint Products and Technologies publishes multiple Web applications; each application is published via a unique port.

  • Each SharePoint Web application is published via only one IAG trunk.

  • The public address of the SharePoint site is different than the internal address of the site.

  • External users access the SharePoint site over HTTPS; internal users access the same site over HTTP.

Publishing multiple SharePoint Web applications on a single port

A topology that publishes multiple SharePoint Web applications on a single port consists of the following:

  • A server running SharePoint Products and Technologies publishes multiple Web applications on a single port, each with a unique host header.

  • Each SharePoint Web application is published via only one IAG trunk.

  • The public address of the SharePoint site is different than the internal address of the site.

  • External users access the SharePoint site over HTTPS; internal users access the same site over HTTP.

Publishing a SharePoint Web application when using identical internal and public addresses

This topology is commonly used in hosted services environments. This topology consists of the following:

  • A server running SharePoint Products and Technologies publishes a single Web application.

  • The SharePoint Web application is published via only one IAG trunk.

  • The public address of the SharePoint site is identical to the internal address of the site.

  • External users access the SharePoint site over HTTPS; internal users access the same site over HTTP.

Publishing a SharePoint Web application via multiple IAG trunks

This topology consists of the following:

  • A server running SharePoint Products and Technologies publishes a single Web application.

  • The SharePoint Web application is published via multiple IAG trunks.

  • The public address of the SharePoint site is different than the internal address of the site.

  • External users access the SharePoint site over HTTPS; internal users access the same site over HTTP.
