This topic describes the billing and settlement rules for pay-as-you-go ECS resources. Pay-as-you-go allows you to pay for the amount of resources you actually use. You can purchase and release resources on demand, and scale up as your business grows. Pay-as-you-go helps reduce your costs by 30% to 80% compared with the investment of a traditional host.
Pay-as-you-go resources are billed based on the billing cycle and paid each hour. If you have a quota agreement with Alibaba Cloud, fees are deducted when the cumulative consumption of your account exceeds the quota. You must settle the payment at least once a month.
You can change the billing method of pay-as-you-go ECS resources you created. For more information, see Switch the billing method from pay-as-you-go to subscription.
- ECS instances
- Internet bandwidth (Pay-By-Bandwidth)
Snapshots start to incur fees after you create them.
If a pay-as-you-go ECS instance is out of service due to overdue payment, the billing of its resources is suspended. The billing resumes after you settle the overdue payment and reactivate the instance.
|ECS instances||The billing duration is affected by the network type of the instance.
You can purchase reserved instances to reduce your costs. For more information, see Reserved instance overview.
|Images||The billing starts when the instance is created and stops when the instance is released.|
|Cloud disks (system disks)||The billing starts when the instance is created and stops when the instance is released.|
|Cloud disks (data disks)||The billing starts when the data disk is created and stops when the data disk is released.|
|Internet bandwidth (Pay-By-Bandwidth)||The billing starts when Internet bandwidth (Pay-By-Bandwidth) is enabled and stops
when Internet bandwidth is disabled or the ECS instance is released.
For information about how to disable Internet bandwidth, see Change Internet bandwidth.
|Snapshots||The billing starts when a snapshot is created and stops when the snapshot is deleted.|
To avoid unexpected fees incurred when the active duration is exceeded, we recommend that you enable the automatic release feature. If automatic release is enabled, the billing stops when the resources are released. The stop time is accurate to seconds.
|Resource||Billing cycle||Formula||Unit price|
|ECS instances||Second||Unit price of the instance type × Billing duration||For more information, see Instance Fee on ECS Pricing.
Note Local disks attached to an instance are billed together with the instance.
|Images||Second||Image unit price × Billing duration||You can view the price on the purchase page and in the Alibaba image marketplace.|
|Cloud disks (system disks)||Second||Disk unit price × Disk capacity × Billing duration||For more information, choose ECS Pricing.
Note The price on the page is USD/100 GiB/hour. Divide it by 100 to obtain the unit price per GiB.
|Cloud disks (data disks)||Second||Disk unit price × Disk capacity × Billing duration||For more information, choose ECS Pricing.
Note The price for a pay-as-you-go disk on the page is USD/100 GiB/hour. Divide it by 100 to obtain the unit price per GiB.
|Internet bandwidth (Pay-By-Bandwidth)||Second||Bandwidth unit price × Bandwidth value × Billing duration
For more information, see Billing methods of public bandwidth.
|Tiered pricing is used for fixed bandwidth. You can select a bandwidth value on the purchase page to view the changes in fees.|
|Snapshots||Hour||Snapshot unit price × Snapshot capacity × Billing duration
For more information, see Snapshot billing.
|For more information, see Snapshot Fee on ECS pricing.|
- If the billing cycle is one second, the fee generated each second is added on to the bill. If an hourly price is displayed, you can divide the price by 3600 to obtain the price per second.
- If the billing cycle is one hour, the fee generated every hour is added on to the bill. A usage duration less than an hour is calculated as an hour.
- If your default payment method is bank card, the quota is USD 1,000.
- If your default payment method is PayPal or Paytm (India) account, the quota depends on your ECS resource usage.
Fee deduction occurs on three days: due date (T), T+7, and T+14. In fee deduction fails on the due date (T), the system attempts to deduct fees again on the day T+7 and day T+14. If fee deduction fails for these three times, the instance goes out of service on the day T+15.
- Within 15 days after the overdue payment, you can use existing ECS resources but cannot purchase new ECS instances, upgrade the instance, or renew the instance.
- Within 15 days after the instance is out of service, you must submit a ticket to settle the overdue payment and then reactivate the instance. Otherwise, the instance will be automatically released. For information about resource status, see Resource status when an ECS instance is out of service.
- More than 15 days after the instance is out of service, the pay-as-you-go ECS instances are released.
Resource status when an ECS instance is out of service
If all three deductions fail, the ECS instance is out of service. The following table describes the resource status if your ECS instance is out of service.
|Resource||Within 15 days after out-of-service||More than 15 days after out-of-service|
|ECS instances||The ECS instance is retained but it is out of service.
When a pay-as-you-go ECS instance is Out of service, it enters the Expired state and the billing stops. After the instance stops providing services, you cannot remotely connect to the instance, or access websites deployed on the instance. Service errors will occur.
|The ECS instance is released.
Note If your ECS instance is released due to overdue payment, Alibaba Cloud will send you an email notification.
|Images||Images are unavailable.||Images are unavailable.|
Note If the performance of cloud disks or local disks is limited, they cannot properly process I/O read and write requests. This affects the normal running of the ECS instance mounted to these disks, such as excessive time needed to perform operations and unpredictable power-off or restart failures for some operating systems.
|Snapshots||All snapshots are retained but automatic snapshots cannot be created.||All snapshots will be deleted except for those used to create cloud disks or custom images.|
