Why AWS Global Infrastructure matters
AWS global infrastructure is the most secure, reliable, and extensive cloud, providing diverse infrastructure solutions for running your applications anywhere. **With three Availability Zones (AZs) per Region** and optimized data centers, AWS global infrastructure maximizes resilience, performance, and innovation. Using 9+ million kilometers of fiber optic cabling, AWS’s global network backbone enables faster data transfer, reduced latency, and enhanced application performance.

Should rather be "With a **minimum **of three Availability Zones"

You're correct. AWS Regions typically have a minimum of three Availability Zones, not exactly three per Region. The AWS global infrastructure is composed of multiple Regions worldwide, with each Region containing multiple Availability Zones. According to the current information, AWS operates in 25 geographic Regions with 84 Availability Zones, with plans for additional expansion. Some Regions may have more than three Availability Zones, as the total number of AZs (84) divided by the number of Regions (25) averages more than three AZs per Region.

The AWS global infrastructure is designed with this multi-AZ architecture to provide high availability, fault tolerance, and resilience. Availability Zones within a Region are physically separated but connected through low-latency, high-throughput, and highly redundant networking, allowing customers to design applications that can automatically fail over between zones without interruption.
