Topologies for Web Synchronization

  • Άρθρο

Applies to: SQL Server

You can choose from a variety of Microsoft SQL Server Web synchronization replication topologies. Common ways to configure Web synchronization include:

  • Single server

  • Two servers

  • Multiple Microsoft Internet Information Services (IIS) systems and SQL Server republishing

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

Single Server

In the simplest topology, IIS, the SQL Server Publisher, and the SQL Server 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 SQL Server Publisher/Distributor be on separate computers.

Two Servers

You can place IIS on one server and configure the SQL Server 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.

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 SQL Server, 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.
