Users & Groups are Identity & Access Management (IAM) components:

👤 User

A User is an individual person or identity who can log in and use cloud resources.

👉 Example:

Ram (Developer) Priya (Admin)

Individual accounts that access OCI resources Have credentials (password, API keys) Assigned to groups for permission management

Steps to Create User in OCI:

Step:1.

Step.2.

Step.3.

Step.4.

👥 Group

A Group is a collection of users with similar roles.

👉 Instead of giving permissions to each user, you assign them to a group. Collections of users with similar responsibilities Make permission management easier Example: "DatabaseAdmins", "Developers", "Finance"

🧠 Simple Real-Life Analogy

Think of a company:

Employees = Users 👤 Departments (HR, IT, Finance) = Groups 👥

👉 You don’t give access individually—you give it to the department.

How They Work Together

Create Users (Ram, Priya) Create Groups (Developers, Admins) Add users to groups Assign permissions to groups (not users) 🔐 Why Use Groups?

✔️ Easier management

✔️ Better security

✔️ Scalable (add/remove users easily)

👉 Example:

Add Ram to "Developers" → he automatically gets all developer access ⚡ Quick Example Group: Developers Users: Ram, John

Developers can access Dev Compartment

👉 Both users now get access without separate rules.
