Overview

CloudTable supports pay-per-use and yearly/monthly billing modes to meet user requirements in different scenarios.

Pay-per-use: A postpaid billing mode. You pay as you go and just pay for what you use. The prices are calculated by the second but billed every hour. This mode allows you to adjust resource usage easily. You neither need to prepare for resources in advance, nor end up with excessive or insufficient preset resources. This mode is typically suitable for scenarios with sudden traffic bursts, such as e-commerce flash sales.
Yearly/monthly: You pay for the cluster by year or month, in advance.

If the order for a yearly/monthly cluster encounters an anomaly, the full fee will be refunded. However, if the cluster is successfully created and its status is normal, the cluster's billing mode will automatically change to pay-per-use in this scenario.
