Overview

CCI supports two billing modes: pay-per-use and packages.

CCI supports pay-per-use billing, accurate to seconds. You use the resources first and then pay for them. Bills are settled by the hour.
Packages allow you to flexibly adjust resource usage. You neither need to prepare for resources in advance, nor end up with excessive or insufficient preset resources. They are a good option for scenarios where there are sudden traffic bursts, such as e-commerce promotions.
