Load balancing is a very general term that means different things to different people. It is usually fairly obvious when you need to do load balancing, but far from obvious what load balancing you should actually be doing. Is it your web server that’s overloaded? The database? Are the disks too slow to keep up? Do you need to do some caching? All of the above?

Practical Load Balancing aims to address all of these problems. First we’ll give you a nice introduction to load balancing as we see it. We’ll then cover some fundamentals and show you how to find out where you can boost performance. Many people try random solutions in the hope that it will make things better - we’ll give you the techniques to locate and isolate specific problems! No more guesswork!

Next we walk through the most common scenarios and show you how to implement solutions using state of the art Open Source software. We will give you instructions that actually work and ensure that the examples we give are self contained - you won’t need to complete Chapter 8 before you can make use of Chapter 9!

For more information, check out the book’s official site at www.loadbalancingbook.com. Right now it’s under construction, but we will be updating it through out the writing process.
