Overview

There are yearly/monthly and pay-per-use billing modes to meet your requirements.

Yearly/Monthly is a prepaid billing. You pay in advance for a subscription, and in exchange, you get a discounted rate. The longer the subscription term, the higher the discount. This mode is generally suitable for mature businesses with long-term stable equipment needs.
Pay-per-use is a postpaid billing mode. You pay as you go and just pay for what you use. This allows you to adjust resource usage easily.

Table 1 compares the two billing modes.
