This topic describes the pay-as-you-go billing method for Hologres.
Example: You purchase a pay-as-you-go Hologres instance at the Alibaba Cloud International site (alibabacloud.com). 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 deducts 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 renew your instance within 14 days, 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 if your business no longer requires it. 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.
