A Gentoo Linux Advanced Reference Architecture – The book "A Gentoo Linux Advanced Reference Architecture" is meant as a resource displaying the powerful features of many free software solutions that are supported on top of Gentoo Linux. It is a deep-dive approach in many aspects related to processes, supportability, maintainability based on Gentoo Linux system deployments. Unlike the existing, per-application documents that exist on the Internet (and which are a valuable resource to get into the gory details of many applications) and the per-distribution guides that provide information on using that particular distribution, this book will focus more on architecturing IT infrastructure for medium-sized enterprises. Smaller enterprises might find the reference architecture here too expensive or large – however, many services described in the book can be slimmed down into a smaller deployment as well.
