This is official Amazon Web Services (AWS) documentation for AWS Identity and Access Management (IAM). This user guide provides a conceptual overview of IAM, a web service that enables AWS customers to manage users and user permissions within AWS. The guide also describes business use cases, explains AWS permissions and policies, describes how to integrate IAM with other AWS products and services, and provides instructions on using the various features with the AWS Management Console (an easy-to-use graphical interface), the command line interface (CLI), or the IAM API. This documentation is offered for free here as a Kindle book, or you can read it online or in PDF format at http://aws.amazon.com/documentation/iam/.
