To deliver low latency to users around the world, which characteristic of the AWS Cloud is most relevant?

The most relevant characteristic for delivering low latency to users globally is AWS's Global Infrastructure. This refers to AWS's worldwide network of Regions and Availability Zones, which allows you to deploy applications geographically closer to your end-users. By reducing the physical distance data needs to travel, latency is significantly decreased. Pay-as-you-go pricing describes the billing model, not a technical feature for latency. Managed services offload operational burden but don't inherently guarantee low latency globally without leveraging the underlying infrastructure. Economy of scale refers to cost benefits from AWS's large customer base, which is unrelated to network latency.
