IAM allows you to create and manage users and groups. Users represent individuals who can interact with AWS resources, while groups make it easier to manage permissions for multiple users.IAM uses policies to define permissions. Policies are JSON documents that specify what actions are allowed or denied on AWS resources. You can attach policies to users, groups, or roles. The prerequisites for this course are
