AWS Infrastructure

• AWS infrastructure has multiple regions.
• Each region has multiple Availability Zones.
• Each AZ contains data centers (with databases, servers, and cloud resources).

Scope for Access (Azure RBAC)

• Owner
• Contributor
  • Example: Virtual Machines
• Resource Manager
  • Subscription (multiple subscriptions possible)
  • Resource Group (linked to subscription and location)
    • Resources (e.g., VM, Storage Account, etc.)

RBAC → multiple policies for fine-grained access control.
