Techniques you'll need to master:
Windows Server 2003 provides both the Cluster Service and Network Load Balancing for load balancing, high availability, and high reliability. Server systems and all their components have a rated reliability number (usually expressed in hours) called the Mean Time Between Failure ( MTBF ). The MTBF shows the measured failure rate of the system's individual components. A high-availability server is expected to be available at all times: 7 days a week, 52 weeks a year. In effect, the system is built and deployed with the consideration that it would never be offline. This is, of course, not always true because every server needs to be shut down periodically for upgrades or to recover from system failures. High-availability server deployments are normally undertaken as follows :
