This is a beginner book. However, it is recommended that you have a basic knowledge of how computers work and are able to install software on your computer. It was written with college students in mind. This book introduces you to cloud computing and Linux. It covers fundamentals of cloud computing and Linux at the beginner level. There are many good books and websites on cloud computing and Linux. But not many books cover both. This book is unique for two reasons: 1) It focuses on basic concepts that can apply to most public clouds and Linux distros instead of explaining a particular one in details. This way readers can have a good understanding of overall picture of cloud computing and Linux. When they need more details of certain topic, they can search the Internet to find it. 2) It includes many review questions and practice projects so that readers not only read, but they can also type, get frustrated, and enjoy the success when their cloud computing finally works. This book cannot be completed in one hour, or one day because of the hands-on requirement. The recommended duration for completing this book is about 10 hours a week for two months. This book is not an in-depth cover of any particular topic because we want you to finish the book by the end of the semester.
