One of the main advantages of cloud computing is the ability to trade fixed capital expenditures for variable operating expenses. By moving to the AWS Cloud, the company pays only for the resources it uses on a per-usage basis, reducing the need for large upfront investments in data center infrastructure. This benefit allows for more flexible and cost-effective spending based on actual usage. Other options, such as increased speed and agility or global reach, are also cloud benefits but do not specifically address the shift from fixed to variable expenses.
