Understand what IAM Groups are
Earlier, we learned that
-
IAM controls who can access AWS
-
Users represent people or systems
-
Permissions decide what actions are allowed
Groups and roles help manage these permissions more easily and safely.
Office Analogy
In an office, employees are divided into departments with specific access
Sometimes, an employee is given temporary access to handle a special task.
Transition to Concept
IAM Groups work like departments (HR, Finance), giving the same access to all members.
IAM Roles work like temporary assignments, giving special access only for a short time.
Just like offices group employees into departments and give temporary responsibilities when needed, AWS uses Groups and Roles to manage access in a smart and secure way.
IAM: What Are Groups?
IAM Groups are collections of users who need the same level of access
Instead of setting permissions for each person, access is given once to the group.
Example (Office):
All employees in the Finance department follow the same rules and access the same files.
Similarly, all users in one IAM Group receive the same permissions.
Why Groups are useful
Easier
Permissions are managed in one place instead of for each user.
Faster
Adding a user to a group instantly gives them the required access.
Less error-prone
Reduces mistakes from assigning wrong permissions individually.

What Are IAM Roles?
IAM Roles give temporary access to AWS for a specific task.
Example :
An employee is given temporary access to the Finance system during an audit.
After the audit ends, that access is removed
This is how an IAM Role works.
Why Roles Are Important
Temporary access
Better security
No shared logins
Roles give access only for the time a task is needed.
Access is limited
Reducing risk
Users don’t need permanent usernames or passwords
This keeps access safe and controlled.
