The default billing method for Object Storage Service (OSS) resources is pay-as-you-go. Compared with the pay-as-you-go billing method, resource plans are more cost-effective. To reduce costs, we recommend that you purchase resource plans. Resource plans can be used to offset resource fees, such as storage and traffic fees. The overage is billed on an hourly basis. If a resource plan expires or the actual resource usage exceeds the quota of the resource plan, the pay-as-you-go billing method is automatically used.

Resource plan types

Resource plan Description
Storage plan Used to offset the storage fees for OSS objects or Elastic Compute Service (ECS) snapshots.
Standard locally redundant storage (LRS) plan Used to offset the storage fees for Standard (LRS) objects.
Infrequent Access (IA) (LRS) plan Used to offset the storage fees for IA (LRS) objects.
Data transfer plan Used to offset OSS traffic fees.
Outbound traffic plan Used to offset the traffic fees generated when data is transferred from OSS to the client over the Internet.
Transfer acceleration plan Used to offset the traffic fees generated when users access OSS by using acceleration endpoints.
DDoS protection basic plan Used to offset the fees that are generated when users reserve Anti-DDoS Pro or Anti-DDoS Premium instance resources.

Purchase suggestions

Suggestion 1: Select resource plan types that are suitable for your business scenarios

In most cases, users purchase both storage plans and outbound traffic plans. Storage plans are used to offset the storage fees for OSS objects and ECS snapshots. Outbound traffic plans are used to offset the fees for accessing OSS objects over the Internet.

Scenario Resource plan
Use OSS to store text, images, audio files, and videos as Standard (LRS) objects. Standard (LRS) plan
Create and retain ECS snapshots. Standard (LRS) plan
Browse or download OSS objects over the Internet. Outbound traffic plan

For more information about the scenarios in which all resource plan types are used, see Resource plan types.

Suggestion 2: Select resource plan types based on specific billable items in your bill

If an OSS bill is generated in your account, we recommend that you select resource plan typesbased on specific billable items in billing details.

For example, if the billable item is the storage usage of Standard (LRS) objects, you can purchase Standard (LRS) plans to offset the storage fees.

Billable item

Suggestion 3: Select resource plan types based on the usage of specific billable items in your bill

If an OSS bill is generated in your account, we recommend that you select resource plan typesbased on the usage of specific billable items in billing details.

For example, if the storage usage of Standard (LRS) objects is 40 GB per hour, you can purchase Standard (LRS) plans with a capacity of 40 GB to offset the storage fees.

Suggestion 4: Check resource plans that are billed on an hourly basis after you purchase the plans

  1. On the Details page, view the types, usage, and consumption time of billable items.
  2. On the Resource Plan List page, view the types, total amounts, and effective time of resource plans that are in effect.
  3. Compare the billable items and resource plans.
    Sample cause Solution
    The bill contains outbound traffic over the Internet (NetworkOut), but the resource plan list does not contain outbound traffic plans. Purchase outbound traffic plans.
    The bill contains the storage usage of Standard (LRS) objects, but the resource plan list does not contain Standard (LRS) plans. Purchase Standard (LRS) plans.
    The storage usage of Standard (LRS) objects in the bill is 100 GB per hour, but the Standard (LRS) plan in the resource plan list has a capacity of 40 GB. Upgrade the capacity of the Standard (LRS) plan to 100 GB.
    The bill is generated before you purchase resource plans. None

Offset methods

Method Resource plan Description
Fixed total capacity Storage plan A fixed quota is available every hour. If the fixed quota is not exhausted within one hour, the unused quota cannot be transferred to the next hour.

For example, a resource plan with a capacity of 10 TB can be used to offset fees for storage usage of up to 10 TB per hour.

  • If the storage usage is 9 TB in the first hour, the resource plan can be used to fully offset the storage fees.
  • If the storage usage is 10 TB in the second hour, the resource plan can still be used to fully offset the storage fees.
  • If the storage usage is 11 TB in the third hour, the resource plan can be used to offset the storage fees for the first 10 TB. You are charged for the excess 1 TB on a pay-as-you-go basis.
Monthly subscription cycle Outbound traffic plan A fixed quota is available every month. The full quota is restored on the first day of the next month. The unused quota cannot be transferred to the next month.

For example, if you purchase an outbound traffic plan with a capacity of 100 GB and a validity period of six months, you can use the traffic plan to offset fees for 100 GB of download traffic over the Internet per month within six months. The overage is billed on a pay-as-you-go basis.

Decreasing total capacity Transfer acceleration plan Transfer acceleration plans are used to offset the fees for actually used resources until the balance in your account is cleared or until the plans expire.

For example, if you purchase a transfer acceleration plan with a capacity of 5 TB and a validity period of three months, you can use the plan to offset fees for 5 TB of transfer acceleration traffic within three months. The overage is billed on a pay-as-you-go basis.

Regions

When you purchase resource plans, you must select the region in which you want to use the resource plans. You do not need to select a region when you purchase a DDoS protection basic plan because this plan takes effect in all regions. Region-specific resource plans are available only in the specified regions.

Note You can use the DDoS protection basic plan to offset the fees generated for Anti-DDoS Pro or Anti-DDoS Premium instances in different regions. One DDoS protection basic plan can be used to offset only the fees generated for a single instance in a single region within the same hour. If fees are generated in multiple regions within the same hour, you can purchase multiple DDoS protection basic plans to offset the fees.
Region type Description
All regions Offset resource usage fees in all regions.
Specified regions Offset resource usage fees only in selected regions.
Regions inside the Chinese mainland Offset resource usage fees in multiple regions inside the Chinese mainland.
Transfer acceleration regions Offset traffic fees generated when you use an acceleration endpoint to accelerate uploads or downloads. The acceleration endpoint can be used to access OSS buckets across different regions.
Transfer acceleration M2M Offset transfer acceleration fees generated when you use an acceleration endpoint to accelerate uploads (AccM2MIn) or downloads (AccM2MOut). The acceleration endpoint can be used to access OSS buckets across regions inside the Chinese mainland.
Transfer acceleration M2O_O2M Offset transfer acceleration fees generated when you use an acceleration endpoint to accelerate uploads (AccM2OIn or AccO2MIn) or downloads (AccM2OOut or AccO2MOut). The acceleration endpoint can be used to access OSS buckets from regions outside the Chinese mainland to the Chinese mainland or from the Chinese mainland to regions outside the Chinese mainland.
Transfer acceleration O2O Offset transfer acceleration fees generated when you use an acceleration endpoint to accelerate uploads (AccO2OIn) or downloads (AccO2OOut). The acceleration endpoint can be used to access OSS buckets in regions outside the Chinese mainland.

You can purchase resource plans for the Chinese mainland and region-specific resource plans at the same time. Region-specific resource plans are preferentially used to offset fees. After the quota is exceeded, fees are offset based on resource plans for the Chinese mainland. If the actual usage still exceeds the quota of resource plans for the Chinese mainland, the overage is billed on a pay-as-you-go basis.

For example, resource plans for the China (Qingdao) region can be used to offset only the resource usage fees that are generated in the China (Qingdao) region.

For more information about the regions inside the Chinese mainland that are supported by resource plans for the Chinese mainland, see Regions supported by the resource plans for the Chinese mainland.
