Amazon Web Services (AWS) offers a pay-as-you-go approach to pricing for over 200 cloud services. With AWS you pay only for the individual services you need, for as long as you use them, and without requiring long-term contracts or complex licensing.
Pay-as-you-go lets you easily adapt to changing business needs, with charges on an as-needed and on-demand basis. This reduces the risk of over-provisioning or missing capacity.
