EPUB is an open, industry-standard format for e-books. However, support for EPUB and its many features varies across reading devices and applications. Use your device or app settings to customize the presentation to your liking. Settings that you can customize often include font, font size, single or double column, landscape or portrait mode, and figures that you can click or tap to enlarge.

Many titles include programming code or configuration examples. To optimize the presentation of these elements, view the e-book in single-column, landscape mode and adjust the font size to the smallest setting. In addition to presenting code and configurations in the reflowable text format, we have included images of the code that mimic the presentation found in the print book; therefore, where the reflowable format may compromise the presentation of the code listing, you will see a Click here to view code image link.

To Katie, Samantha, and Conor

I would like to thank the following people.

First and foremost, I want to thank my researcher and writing assistant, Alasdair Gilchrist. This book simply could not have happened without his hard work and dedication.

This book has been in the works for quite a while, and over the course of a few years, it has morphed from what was originally called Cloud Networking Simplified. For a variety of reasons, there were stops and starts, do overs, and evolutions, and in a couple of cases, potential co-authors were brought in. Among them were Dave Asprey, who was a very knowledgeable tech guy before becoming the Bullet Proof Coffee guy, and Brian Gracely, who is still a very knowledgeable tech guy who ended up being the technical reviewer of this version of the book. While this book is its own thing, several of their original contributions influenced this version.

Brian Gracely also gets his own thank you for being the technical reviewer of this book. He kept me on my toes and spent a lot of time reading, reviewing, and verifying my work. This book is much better than it would have been without his efforts.

Finally, I want to thank the great team at Pearson. Always the consummate professionals, they make my job much easier, and they are all a pleasure to work with. Specifically, Id like to thank Executive Editor Mary Beth Ray, who had the patience to keep this project alive through all the iterations. Development Editor Jeff Riley for being a great man behind the curtain. Line Artist Laura Robbins for helping with the whiteboard layouts and line art. And last but not least, the editing team, including Project Editor Mandie Frank, Development Editors Drew Cupp and Jeff Riley, and Copy Editor Keith Cline, who Im sure I drove crazy with my many spelling errors, typing errors, run-on sentences, and use of passive voice. This is my sixth book with Pearson, and every crew Ive worked with has been outstanding. This one is no exception. Thank you all.

Dear Reader,

Thank you for buying (or considering) this book. By way of background, this book is the latest in a series of Networking Simplified books that have covered topics such as basic networking with Cisco Networking Simplified, and other titles that have taken a simplified approach to Voice over IP (VoIP), security, and home networking.

If you are not familiar with the approach of the Networking Simplified books, the idea is to explain networking concepts and technologies to people who are not intending to become technical experts, but want to know what underlying networking technologies are and how they work at a high level. This includes business and marketing folks, salespeople, investors, people who work in technical companies but in nontechnical roles, and even technical people from different vocations who want a cursory introduction to networking.
