Consumption-based pricing is quickly becoming a powerful approach, providing flexibility that allows customers to pay only for the resources they use—whether it’s storage, API calls, or CPU hours. Known as pay-as-you-go, metered billing, or usage-based pricing, this model is increasingly popular across industries like cloud computing, IaaS, SaaS. While it offers clear benefits for both users and providers, this flexibility brings unique challenges to the forefront, particularly around revenue predictability and effective resource allocation.
