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 term, and in exchange, you get a discounted rate. The longer the subscription term, the bigger the discount. Yearly/Monthly billing is a good option for long-term, stable services.
Pay-per-use is a postpaid billing. You pay as you go and just pay for what you use. The usage is calculated by the second but billed every hour. This mode allows you to flexibly adjust resource usage. You neither need to prepare for resources in advance, nor end up with excessive or insufficient preset resources. Pay-per-use billing is a good option for scenarios where there are sudden traffic bursts, such as e-commerce promotions.

You can select different billing modes for your clusters or nodes on the CCE console. You can, for example, select pay-per-use for your nodes running in a cluster which is billed on the yearly/monthly basis.

However, on the CCE console, the related cloud service resources cannot be billed on the yearly/monthly mode. These resources are billed on the pay-per-use mode by default when they are automatically created in the CCE cluster. To purchase yearly/monthly cloud service resources, go to their respective consoles. For details, see their billing descriptions.

**Table 1** Cluster billing mode
Billing Mode	Yearly/Monthly	Pay-per-use
Payment	Prepaid Billed by the subscription term you purchase	Postpaid Calculated by the second but billed every hour
Billed Usage Period	Billed by the subscription term you purchase	Calculated by the second but billed every hour
Billing for a Hibernated Cluster	A cluster billed in yearly/monthly mode cannot be hibernated.	You do not need to pay for the management of a hibernated cluster, but the cloud services used in the cluster, such as EVS disks, EIPs, and bandwidths will be charged in their own billing modes like yearly/monthly or pay-per-use. NOTE: In a hibernated cluster, the worker nodes (ECSs) will not be stopped. To stop all nodes, select Shut down all nodes in the cluster. You can also stop a node on the ECS console after hibernating a cluster. For details, see Stopping a Node.
Changing the Billing Mode	Yearly/Monthly can be changed to pay-per-use only after the yearly/monthly subscription expires.	Pay-per-use can be changed to yearly/monthly.
