Overview
There are yearly/monthly, spot pricing, and pay-per-use billing modes.
- 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 resource 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.
- Spot pricing is a postpaid billing mode. Node (ECS) prices are adjusted gradually based on long-term trends in supply and demand for spot instance capacity. The node usage is calculated by the second but billed every hour. Spot pricing enables you to buy nodes at a discounted price while maintaining the same performance level as regular nodes. However, when inventory runs low, or the market price rises and exceeds the highest price you are willing to pay, the system automatically reclaims your nodes at short notice. Spot pricing applies when you want to drive down cloud costs.
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 billed items (Billed Items) cannot be billed on the yearly/monthly basis. These resources are billed on the pay-per-use basis by default if they are automatically created on the CCE console. To purchase yearly/monthly cloud service resources, go to their respective consoles. For details, see their billing descriptions.

Billing for a Hibernated Cluster |
A cluster billed on the yearly/monthly basis cannot be hibernated. |
You do not need to pay for the management of a hibernated cluster, but the cloud service resources 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. Most nodes are no longer billed after they are stopped, excluding certain types of ECSs (ones with local disks attached, such as disk-intensive and ultra-high I/O disks). For details, see Billing. |

Recommended when the resource demands are likely to fluctuate and you want more flexibility. |
Ideal for stateless, cost-sensitive applications that can tolerate interruptions. Not recommended for workloads that need to run for a long time or that require high stability. |
