Aws: Amazon Web Services, the Ultimate Guide for Beginners to Advanced

This "book" is only 120 pages of double-spaced text. It is self-published, there are numerous typos and no information that is not on the AWS web pages. I was looking for a current "dummies" type guide so I bought this for the publication date. I was wrong, this is of no value because there is no explanation. DO NOT confuse this with a guide book - it is not.PS - There are typos in the positive reviews leading one to wonder about their source.
