Billing Items

Billing

You will be billed for instance flavors, images, EVS disks, and EIP bandwidths. For details, see Table 1.

The billing items marked with asterisks (*) are mandatory.

Table 1 ECS billing items

Billing Item

Description

Billing Mode

Formula

*ECS

Billed by ECS flavor, including vCPUs and memory. Computing and storage capabilities vary by the number of vCPUs and memory size.

If a pay-per-use or spot ECS is stopped, the ECS flavor and image will no longer be billed. To save money, you can temporarily stop the ECSs that you do not need at that moment.

For details, see Billing for a Stopped ECS (pay-per-use) or Billing for a Stopped Spot Instance (spot pricing).

Yearly/Monthly, pay-per-use, and spot pricing

Unit price x Required duration

For details about the unit price, see Specifications Price on ECS Pricing Details.

*Image
  • Public images are free of charge.
  • Private images: Private images for system disks and data disks can be used for free. For full-ECS images, you will be billed for using the server backup vault of CBR.
  • Shared images: Shared images for system disks and data disks can be used for free. For full-ECS images shared by others, you will be billed for using the server backup vault of CBR.

Yearly/Monthly, pay-per-use, and spot pricing

Unit price x Required duration

The unit price of an image is that displayed on the purchase page and KooGallery.

*EVS disk (system disk)

Billed by EVS disk type and capacity. When you purchase an ECS, a 40 GiB system disk is selected by default. You can select a higher capacity as required.

Regardless of whether you use the disk, you will be billed right away after purchasing it.

Yearly/monthly and pay-per-use

Unit price x Required duration

For details about the EVS disk unit price, see Disk Price on ECS Pricing Details or EVS Pricing Details.

EVS disk (data disk)

If you have additional storage requirements, you need to purchase more data disks.

Billed by EVS disk type and capacity.

Yearly/monthly and pay-per-use

Unit price x Required duration

EIP bandwidth

An EIP is required if the ECS needs to access the Internet.

Billed by bandwidth, traffic, and the EIP reservation price.

  • EIP for a yearly/monthly ECS: billed by bandwidth
  • EIP for a pay-per-use ECS: billed by bandwidth, traffic, or shared bandwidth. You are also billed for EIP reservation if you do not bind the EIP to any instance.
    NOTE:

    If the EIP has been bound to an ECS, the EIP reservation price is 0.

Yearly/monthly and pay-per-use

You can purchase a bandwidth add-on package or a shared traffic package.

Tiered pricing based on fixed bandwidth

  • 0 Mbit/s to 5 Mbit/s (included): billed at a fixed unit price per Mbit/s
  • Greater than 5 Mbit/s: billed at a different price per Mbit/s

For details about the unit price, see Bandwidth Price on ECS Pricing Details or EIP Pricing Details.

Billing Examples

Suppose you purchased a one-month ECS subscription (c6.large.2 with a CentOS 7.9 64-bit image and a bandwidth of 6 Mbit/s) on March 08, 2023, 15:50:04, and renewed the subscription for one more month before the initial subscription expired. That would include two usage periods:
  • March 08, 2023, 15:50:04 to April 08, 2023, 23:59:59
  • April 08, 2023, 23:59:59 to May 08, 2023, 23:59:59

You need to pay for each billing cycle first. Resources are billed individually. The billing formula is shown in Table 2.
