AWS Cloud Practitioner CLF-C02 Practice Question

The primary financial advantage of using the AWS Cloud is the ability to trade large, upfront capital expenses (CapEx) for variable operational expenses (OpEx). Instead of investing in physical data centers and servers, organizations pay only for the computing resources they consume on a pay-as-you-go basis. This eliminates the risks of over-provisioning or under-provisioning and allows costs to scale directly with business usage. While some services offer fixed costs (like Reserved Instances), the core model is variable. The cloud reduces, but does not eliminate, operational costs or the need for IT staff.
