AWS Decoded
Amazon's cloud catalogue, translated into plain English.
AWS Decoded covers Amazon's cloud the same way its sister site covers Azure: service by service, in plain language, organised by the problem rather than the catalogue.
It covers the core building blocks — EC2, S3, the database family, VPC networking, IAM — and is explicit about the many places where AWS offers several overlapping answers to the same question.
Pricing models and their traps get their own treatment, since AWS bills for things that are easy not to notice.
Not online yet. This one is written and waiting to be deployed. When it goes live it will be published on this domain and linked from here.
