The writing of this book is horrible. It's extremely hard to understand what the author wanna express. The author just mix a lof of abstract cloud concepts with detailed AWS operation. It really difficult to read due to this unorganised writing and structure.
VERY BAD READING EXPERIENCE.
TORTURE on reading this book.
MAIN 3 ISSUES NEEDS TO BE LEARNED ABOUT AWS BELOW:
1. OPEN A AWS ACCOUNT ( 1 YEAR FREE)
2. S3,including simple DB
3. EC2
Trying to distinguish between concept and technical operation. Book should need to be rewrtten and reorganized.
but hopefully reader can catch the point of AWS, which is useful for service and statup.
