Cloud security and cost

Run cloud workloads safely and economically.

📖 Key ideas

Shared responsibility: provider secures the cloud; you secure what you put in it.
Use MFA, least-privilege IAM, encryption and logging.
Avoid public storage buckets by accident.
Control costs: budgets, alerts, right-sizing, reserved/spot instances.
Tag resources by project and owner.

💡 Real-life example: Cloud security and cost control are locking your rented flat and switching off lights you don't use.
