− Yearly/Monthly is a prepaid billing mode. You pay in advance for a subscription term. Before purchasing yearly/monthly resources, make sure you have a valid payment method configured.

− Pay-per-use is a postpaid mode. In this mode, you pay only for what you use.

If you want to ensure resource stability over a certain period of time, yearly/monthly billing is a good choice.

The following are some service scenarios applicable to this billing mode:

• Long-term workloads with stable resource requirements, such as official websites, online malls, and blogs.

• Long-term projects, such as scientific research projects and large-scale events.

• Workloads with predictable traffic bursts, for example, e-commerce promotions or festivals.

• Workloads with high data security requirements.

Pay-per-use is, a postpaid billing mode, useful if you do not want to pay upfront or if you want to avoid a long-term commitment.

Pay-per-use billing is good for short-term, bursty, or unpredictable workloads that cannot tolerate any interruptions, such as applications for e-commerce promotion, temporary testing, and scientific computing.
