3. What is region?

A region in cloud computing is a specific physical geographical area where a cloud provider houses its data centers.**

Geographic Location: A distinct area on the map (like Mumbai, India or USA) containing physical hardware.

Availability Zones : Every region contains multiple isolated data centers called Availability Zones, which help prevent total outages if one facility fails.

Example: Mumbai Region ├── AD 1 ├── AD 2 ├── AD 3

A Fault Domain (FD) is a grouping of hardware within an Availability Domain that is designed to protect resources from hardware failures and maintenance events.

An AD contains multiple Fault Domains.

Region │ ├── Availability Domain (AD) ├── Fault Domain 1 ├── Fault Domain 2 ├── Fault Domain 3**

example: instead of placing all our application servers in FD1, we can distribute them across FD1, FD2, and FD3
