Preface

AppFog is a cloud-based solution that allows users to quickly build and deploy applications without having to handle server configuration and setup. This book is intended to help you to quickly get started using AppFog and learn to create and deploy applications to the AppFog cloud.

What this book covers

Chapter 1, Getting Started With AppFog, creates an account with AppFog and gets your first application running.

Chapter 2, Using the Command-line Tool, installs and uses the command line tool to download an application from AppFog, then modifies and uploads it back to the cloud.

Chapter 5, Command-line Reference, helps you learn about the many command line tools available.

Appendix, Installing the AppFog Gem, helps you install the Ruby Gem to be able to use the command line tools.
