Step-by-step explanation:
The purpose of Cloud Billing is to provide a method for tracking and managing the costs associated with using cloud services. It allows businesses and individuals to monitor their usage and pay for only the resources they consume.
Cloud Billing relates to options like paying the purchase cost, up-front cost, or periodic cost by offering a flexible and scalable payment model. With traditional payment models, customers may have to pay high upfront costs to purchase and maintain hardware and software. However, with Cloud Billing, they can pay only for the resources they need and use, eliminating the need for large upfront investments.
For example, a company can choose to pay a monthly fee to a cloud service provider and use the resources as needed. This allows them to scale up or down based on their requirements, potentially saving money compared to purchasing and maintaining their own infrastructure.
