When migrating on-premises infrastructure to AWS, which cloud advantage helps reduce upfront capital expenses?

Trading fixed expense for variable expense is a core cloud advantage that directly reduces upfront capital expenditure. Instead of purchasing and maintaining physical hardware (a fixed, upfront cost), you pay for resources as you consume them (a variable operational cost). This eliminates the need for large initial investments in data centers, servers, and networking equipment. "Go global in minutes" and "Increase speed and agility" are benefits of the cloud, but they don't directly address the reduction of upfront capital expenses. While they can lead to business advantages, they describe operational improvements rather than financial models. "Benefit from massive economies of scale" refers to cost savings due to AWS's large infrastructure, which contributes to lower variable costs, but the direct mechanism for reducing upfront capital is the shift from fixed to variable spending.
