AWS Region is a physical location where AWS maintains multiple data centers that are interconnected by a low-latency network. Each region is a separate geographic area, identified by a unique name and code, such as us-east-1 or eu-west-2. AWS Regions are strategically located in different parts of the world to provide customers with a wide selection of geographic locations for hosting their resources, applications, and services.
Each AWS Region consists of two or more Availability Zones (AZs), which are physically separate data centers located within a single region. Each AZ is designed to be highly available and fault-tolerant, with independent power, cooling, and networking infrastructure.
