How to configure and use Amazon’s free IAM service
Amazon Web Services has a built-in service that controls access to AWS resources. This service, called IAM (Identity and Access Management), allows administrators to control who, what, and where any given user can perform an action in a resource.
The following list contains all the key features available when using IAM in your AWS environment.
– Shared access: Using IAM we can delegate permission to another individual to manage AWS resources without sharing passwords or access keys.
– Flexible permission: We can assign permission to specific resources and we can take advantage of such flexibility and give permission to specific resources within a service. (A bucket in S3 or an EC2 instance, for example.)
