AWS -IAM - Identity Access Management - AWS -DAY -2

IAM service is solving the problem of Authentication and Authorization in AWS

- IAM is a Global Service

1. IAM USER -> When a new user is added, a request will be created to create an IAM user. It's good practice to use an IAM user while practicing.

2. IAM POLICIES -> Policies need to be attached to the IAM user which gives the Authorization for the particular IAM user to access the services.

   -> Users/groups can be assigned JSON Documents call policies(IAM Permissions)

3. IAM Groups -> Creating a group by attaching all the policies will be helpful to just add the IAM user to the group to get all the Authorized access.

4. IAM ROLES ->For performing Action on any AWS services like EC2 role, Lamda, role

   -> While Creating CI/CD pipeline roles will be used.
