I’ve wanted to write a book for a while – mainly because people seemed genuinely interested in the presentations I have given over the past several years at the ApacheCon conferences. While my academic background and most of my project background is in the area of high-availability and resource allocation in clusters (i.e. load-balancing), it seemed that a book on it would either be too high level or too applied. The problem with high level conversation is that you end up boring people to death who are practical and not providing enough hands-on information to those that are engineers.
