IIS server configuration [SQL Server replication]

Topologies for Web Synchronization

[!INCLUDE SQL Server] You can choose from a variety of [!INCLUDEmsCoName] [!INCLUDEssNoVersion] Web synchronization replication topologies. Common ways to configure Web synchronization include:

  • Single server

  • Two servers

  • Multiple [!INCLUDEmsCoName] Internet Information Services (IIS) systems and [!INCLUDEssNoVersion] republishing

For information about configuring Web synchronization, see Configure Web Synchronization.

Single Server

In the simplest topology, IIS, the [!INCLUDEssNoVersion] Publisher, and the [!INCLUDEssNoVersion] Distributor all reside on a single server. Subscribers synchronize by connecting to IIS on the Publisher. The Publisher can be located behind a firewall.

Note

This configuration is recommended only for intranet scenarios. For other scenarios, it is recommended that the IIS server and [!INCLUDEssNoVersion] Publisher/Distributor be on separate computers.

Web synchronization with a single server

Two Servers

You can place IIS on one server and configure the [!INCLUDEssNoVersion] Publisher and Distributor on another server. The server running IIS can be isolated from the Internet by a firewall. Subscribers synchronize by connecting to IIS.

Web synchronization with two servers

Multiple IIS Systems and SQL Server Republishing

If you need to support very large numbers of Subscribers that synchronize at the same time, you can partition the work across multiple computers running IIS.

Web synchronization with multiple IIS servers

If further load balancing is required on the computer running [!INCLUDEssNoVersion], you can create a republishing hierarchy on multiple computers. The top-level Publisher publishes data to Subscribers, which in turn republish the data, load balancing requests from the Subscribers.

Note

Subscribers can only synchronize with a specific Publisher. For example, a Subscriber to republisher A cannot synchronize with republisher B when A is not available.
