Cloud Architecture (AWS VPC, IAM & CDN)
Design secure cloud networks with Virtual Private Clouds (VPCs), subnets, IAM least privilege roles, and CDNs.
What You Will Learn in This Lesson
- VPC architecture: Public subnets vs isolated Private database subnets
- Security Groups and Network Access Control Lists (NACLs)
- IAM (Identity and Access Management) Principle of Least Privilege
Introduction & Core Concept
Cloud platforms like AWS and Google Cloud provide scalable on-demand compute, storage, database, and networking services.
WHY DOES THIS MATTER IN THE REAL WORLD?
Placing databases inside private subnets without public internet IPs prevents 99% of automated external scanning attacks.

- Never grant '*' admin access in IAM policies; adhere strictly to least privilege.
Lesson Summary & Core Takeaways
- Secure cloud architectures separate public ingress from private data layers.
