Summary: Owing to their ability to scale server farms and improve the security and availability of networked applications, load balancers are expected to grow into a multibillion-dollar market in the next few years. Written from the unique perspective of an industry insider, this book explains how this critical technology can be used to solve several challenges in managing today's server farms, Web sites, firewalls, and caches. Chandra Kopparapu offers you a close look at how load balancers work and explores the ability of load balancers to solve a multitude of network and server bottlenecks in the Internet age -- from dramatic improvements in server farm scalability to removing the firewall as a network bottleneck. This book provides a technical discussion of this fast-growing market, covering the full spectrum of topics, from server and firewall load balancing to transparent cache switching to global server load balancing. In the process, he delivers insight into the way new technologies are deployed in network infrastructure and how they work.
