This topic describes the pay-as-you-go billing method for Hologres.
Lifecycle management
If you purchase a pay-as-you-go Hologres instance, Alibaba Cloud charges for computing resources based on the specifications and running duration of the instance, and for storage resources based on the volume and duration of stored data. The payments are settled on an hourly basis. The following figure shows the lifecycle management process of a pay-as-you-go Hologres instance.
Example:
You purchase a pay-as-you-go Hologres instance on the Alibaba Cloud official website. You can use this instance immediately after it is created. The payments are settled on an hourly basis. The system pushes a bill to you and deducts the amount payable from your account balance. If your account has an overdue payment, you can still use the instance. During this period, the system does not push a bill to you. The system pushes a bill and attempts to deduct the amount payable if the overdue payment reaches USD 1,000. If the bill is not paid within 14 days after the deduction fails, the instance is suspended and cannot be used. Make sure that your account has a sufficient balance. Otherwise, the instance may stop running due to overdue payments. If you do not top up your account within 14 days after the instance is suspended, the instance is released and deleted from the console. Data in the instance is also deleted and cannot be recovered.
In addition, you can manually suspend your pay-as-you-go Hologres instance. After you click Stop, the system stops charging for computing resources. However, data stored in your instance is still charged on an hourly basis, even if you do not use Hologres for data analytics. You can also manually resume the instance. After that, the system automatically calculates the fees for computing and storage resources. You can delete the instance based on your business requirements. After that, the system calculates the fees and pushes a bill to you. The system automatically releases the instance after you delete it. Data in the instance is also deleted and cannot be recovered.
The billing method of Hologres instances can be changed from pay-as-you-go to subscription and from subscription to pay-as-you-go.
