Load balancing improves network performance by distributing traffic efficiently so that individual servers are not overwhelmed by sudden fluctuations in activity. Server Load Balancing is a guide to this critical component of high availability, clustering, and fault tolerance, all of which provide the infrastructure for reliable Internet sites and large corporate networks. Much of the information on load balancing comes from vendor-specific manuals that use inconsistent terminology and are often biased toward the products they cover. Server Load Balancing explains to engineers and technicians the concepts and terminology of load balancing and offers practical guidance for planning and implementing it in almost any environment. It includes a configuration guide with diagrams and sample configurations for installing, configuring, and maintaining products from the four major vendors: * Alteon WebSystems * Cisco's CSS Series (formerly ArrowPoint) * F5's BIG-IP * the Foundry ServerIron series By comparing several load balancing products, you'll gain a deeper understanding of the technology and how best to use it to improve your network performance.
No system administrator responsible for traffic management should be without this practical guide.
