IAM - Manage Users, Roles and Permissions
With IAM service you can specify who can access which services and resources
▪ Create and manage AWS Users and Groups
▪ Assign policies (set of permissions)
Different Types of IAM Users
▪ Human Users
▪ System Users: For example Jenkins needs permission to deploy Docker containers on AWS
Groups
▪ For granting access to multiple IAM users
IAM roles
▪ IAM role is similar to an IAM user
▪ Instead of being uniquely associated with one person, a role is intended to be assumable by anyone who needs it
▪ Also Policies cannot be assigned to AWS services directly
▪ So role is used to grant AWS services access to other AWS services
