Which of the following describes AWS Global Infrastructure's design?

The design of AWS Global Infrastructure focuses on minimizing latency and maximizing availability. This is achieved through a network of regions and availability zones that are strategically located around the world. Each AWS region consists of multiple isolated availability zones, which allow for high availability and fault tolerance. By placing data centers in various geographic areas, AWS can ensure that users have quick access to resources due to reduced latency, regardless of where they are located.

This design also enhances the reliability of services because if one availability zone faces an issue, others can continue to operate, thus ensuring that applications remain available and responsive. The infrastructure supports various redundancy mechanisms that help in maintaining data integrity and availability, crucial for global applications and services.

The other options describe attributes that do not accurately capture the core principles of the AWS Global Infrastructure. For instance, a decentralized model without any geographic focus would not be effective for minimizing latency; relying solely on single data centers would compromise both availability and disaster recovery; and suggesting that the infrastructure is exclusively for enterprise-level businesses overlooks the variety of services and accessibility available for individual developers and small businesses.
