What Are the Differences Between Yearly/Monthly and Pay-per-Use Billing Modes?

Yearly/Monthly is a prepaid billing mode in which resources are billed based on the service duration. This cost-effective mode is ideal when the duration of resource usage is predictable. It is recommended for long-term users.

Pay-per-use is a postpaid mode. You are only billed for how long you have actually used your instance. This mode can be a good option when future requirements are unpredictable. Pay-per-use instances are priced by the hour, but if an instance is used for less than one hour, you will be billed based on the actual duration.
