The primary economic advantage of moving to the cloud is transforming capital expenditure (CapEx) to variable costs. In an on-premises environment, companies typically invest in hardware and data centers upfront, which is a CapEx. When they move to the AWS Cloud, they pay only for what they use, converting those large, upfront expenses into smaller, variable costs. The answer about operational efficiency, while a benefit, is not primarily an economic advantage. Similarly, while a company may experience a performance improvement, this is not the primary economic advantage. Global reach is a strategic benefit rather than a direct economic one.
