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, andfault 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 WebSystemsCisco's CSS Series (formerly ArrowPoint)F5's BIG-IPthe Foundry ServerIron seriesBy 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.

Simple Network Management Protocol (SNMP) provides a "simple" set of operations that allows you to more easily monitor and manage network devices like routers, switches, servers, printers, and more. The information you can monitor with SNMP is wide-ranging--from standard items, like the amount of traffic flowing into an interface, to far more esoteric items, like the air temperature inside a router. In spite of its name, though, SNMP is not especially simple to learn.O'Reilly has answered the call for help with a practical introduction that shows how to install, configure, and manage SNMP. Written for network and system administrators, the book introduces the basics of SNMP and then offers a technical background on how to use it effectively. Essential SNMP explores both commercial and open source packages, and elements like OIDs, MIBs, community strings, and traps are covered in depth. The book contains five new chapters and various updates throughout. Other new topics include:Expanded coverage of SNMPv1, SNMPv2, and SNMPv3Expanded coverage of SNMPcThe concepts behind network management and change managementRRDTool and CricketThe use of scripts for a variety of tasksHow Java can be used to create SNMP applicationsNet-SNMP's Perl moduleThe bulk of the book is devoted to discussing, with real examples, how to use SNMP for system and network administration tasks. Administrators will come away with ideas for writing scripts to help them manage their networks, create managed objects, and extend the operation of SNMP agents.Once demystified, SNMP is much more accessible. If you're looking for a way to more easily manage your network, look no further than Essential SNMP, 2nd Edition.

HAProxy is a free and open-source load balancer that enables IT professionals to distribute TCP-based traffic across many backend servers. In this book, the reader will learn how to configure and leverage HAProxy for tasks that include: · Setting up reverse proxies and load-balancing backend servers · Choosing the appropriate load-balancing algorithm · Matching requests against ACLs so that we can route them to the correct servers · Monitoring servers with health checks so that failure is detected early · Managing server persistence so that a client's can be directed to the server where their session data is stored · Configuring verbose logging for TCP and HTTP-based services · Enabling SSL encryption, gzip compression and geolocation · Modifying HTTP headers, rewriting URLs and setting up redirects · Defending against malicious Web activity · Controlling HAProxy from the command line · Adding a backup load balancer

Netflix has come a long way since 1997, when two Silicon Valley entrepreneurs, Marc Ran­dolph and Reed Hastings, decided to start an online DVD store before most people owned a DVD player. They were surprised and elated when launch-day traffic in April 1998 crashed their server and resulted in 150 sales. Today, Netflix has more than 25 million subscribers and annual revenues above $3 billion. Yet long- term success-or even survival-is still far from guaranteed. Journalist Gina Keating recounts the absorbing, fast-paced drama of the company's turbulent rise to the top and its attempt to invent two new kinds of business. First it engaged in a grueling war against video-store behemoth Blockbuster, transforming movie rental forever. Then it jumped into an even bigger battle for online video streaming against Google, Hulu, Amazon, and the big cable companies. Netflix ushered in such innovations as DVD rental by mail, a patented online queue of upcom­ing rentals, and a recommendation algorithm called Cinematch that proved crucial in its struggle against bigger rivals. Yet for all its success, Netflix is still a polariz­ing company. Hastings is often heralded as a visionary-he was named Business Person of the Year in 2010 by Fortune-even as he has been called the nation's worst CEO. Netflix also faces disgruntled customers after price increases and other stumbles that could tarnish the brand forever. The quest to become the world's portal for pre­mium video on demand will determine nothing less than the future of entertainment and the Internet. Drawing on extensive new interviews and her years covering Netflix as a financial and entertainment reporter, Keating makes this tale as absorbing as it is important.
