SUMMARY
This article describes how to configure Network Load Balancing Web services with a back-end SQL server.

Network Load Balancing distributes incoming Transmission Control Protocol/Internet Protocol (TCP/IP) traffic between multiple servers. When you use Network Load Balancing, your clustered programs, especially Web-server programs, can handle more traffic and provide faster response times.



MORE INFORMATION
Network Load Balancing can provide fault tolerance and scalable Web services that use a back-end SQL server. The preferred configuration for this scenario is:
 * Two network adapters for each host are required: one network adapter for cluster traffic and heartbeats, the other network adapter for replication and back-end processes.
 * Locate all cluster hosts on a single broadcast subnet.
 * For additional security, assign a private Internet Protocol (IP) address to the back-end network adapter.
 * Use an Lmhosts hosts file to ensure that the Hosts in the cluster use the back-end network adapter and private address to communicate with each other.
