Overview

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

Pay-per-use is a postpaid billing mode. You pay as you go and just pay for what you use. The fees are calculated by second and settled by hour. This mode allows you to adjust resource usage easily. You do not need to prepare resources in advance, and will not have excessive or insufficient preset resources. Pay-per-use is a good option for scenarios where there are sudden traffic bursts, such as e-commerce promotions.
Yearly/monthly: You pay for the cluster by year or month, in advance.
