Final answer:
Azure Pay-As-You-Go is an example of Operational Expenditure (OpEx), not Capital Expenditure (CapEx), as it involves ongoing costs for services as they are used rather than upfront investments in physical assets.
Step-by-step explanation:
Azure Pay-As-You-Go financing model is not an example of Capital Expenditure (CapEx). Instead, it is an example of Operational Expenditure (OpEx). CapEx refers to the upfront spending of money on physical infrastructure, and in the context of IT, this can mean servers and data centers, with the cost capitalized over time. On the other hand, OpEx refers to spending money on services or products now and being billed for them now. With Azure Pay-As-You-Go, you incur costs as you use cloud services, which classifies as OpEx.
