(Oct 9, 2002) Windows 2000 Advance Server comes with Network Load Balancing service. This allows us to form a cluster of servers that respond to a single ip address.
This in turn is perfect for providing highly scalable and highly redandunt webservice. Websites that are hosted in this cluster will always be up and available, even if one or more of the servers in the cluster farm fails.
Look to this feature in our future web service offerings.
