Object Storage Service:Resource plan overview

Last Updated:Aug 15, 2025

OSS uses a pay-as-you-go billing method by default. For better value, you can purchase OSS resource plans to cover costs for storage, traffic, and other resources. If a resource plan expires or its quota is exhausted, excess usage is automatically billed on a pay-as-you-go basis.

Note

OSS provides free trial resource plans for some features. For more information, see View OSS free trial resource plans.

Purchase recommendations

Suggestion 1: Choose a resource plan type based on your scenario

A common combination is a storage plan and an outbound data transfer plan. The storage plan covers storage costs for OSS. The outbound data transfer plan covers traffic costs for accessing OSS files from the Internet.

Scenario

Resource plan to use

Store files such as text, images, audio, and video in OSS using the Standard LRS storage class.

Standard LRS plan

Browse or download files in OSS over the Internet.

Outbound data transfer plan

For more information about scenarios for all resource plan types, see Resource plan types.

Suggestion 2: Choose a resource plan type based on the billable items in your bill

If you already have an OSS bill, you can check the billable items in your detailed bill to select the appropriate resource plan.

For example, if a billable item is Standard LRS capacity, you can purchase a Standard LRS plan to cover this cost.

Suggestion 3: Choose a resource plan size based on the usage in your bill

If you already have an OSS bill, you can check the usage in your detailed bill to select the appropriate resource plan size.

For example, if your hourly usage for Standard LRS capacity is 40 GB, purchase a 40 GB Standard LRS plan to cover this cost.

Suggestion 4: How to troubleshoot hourly charges after purchasing a plan

  1. On the Detailed Bills page, check the type, usage, and consumption time of the billable item.

  2. On the Resource Plan List page, check the type, total quota, and effective period of your active resource plans.

  3. Compare the billable item with your resource plan.

    Example problem

    Solution

    The bill includes a charge for outbound traffic over Internet (NetworkOut), but you do not have an outbound data transfer plan.

    Purchase an outbound data transfer plan.

    The bill includes a charge for Standard LRS capacity, but you do not have a Standard LRS plan.

    Purchase a Standard LRS plan.

    The bill shows 100 GB of hourly usage for Standard LRS capacity, but your Standard LRS plan has a total quota of 40 GB.

    Upgrade the Standard LRS plan to 100 GB.

    The bill was generated before you purchased the resource plan.

Deduction limitations

  • OSS resource plans can cover costs only for the Alibaba Cloud account that was used to purchase them. They cannot be shared across different accounts.

  • OSS resource plans apply only to the OSS service and cannot be used to cover the costs of other products.

  • OSS resource plans can cover only costs that are incurred after the plan is purchased. They cannot be applied retroactively to costs incurred before the purchase.

  • A resource plan can cover costs only for its corresponding billable item. It cannot be used to cover costs for other billable items. For more information, see Resource plan types.

  • A resource plan for a specific region can only cover costs for its corresponding billable item in that region.

Deduction methods

Resource plan

Example

Total Fixed Amount

  • Storage plan

  • Anti-DDoS Basic plan

A fixed quota is provided every hour. The remaining quota cannot be carried over to the next hour.

  • Storage plan

    For example, a 10 TB storage plan can cover up to 10 TB of storage capacity every hour.

    • If the storage usage in the first hour is 9 TB, the storage cost is fully covered by the storage plan.

    • If the storage usage in the second hour is 10 TB, the storage cost is fully covered by the storage plan.

    • If the storage usage in the third hour is 11 TB, the storage plan covers 10 TB, and the excess 1 TB is billed on a pay-as-you-go basis.

  • Anti-DDoS Basic plan

    For example, if you purchase two six-month Anti-DDoS Basic plans for a single instance, the plans can cover the reservation and early release fees for up to two Anti-DDoS instances every hour.

    • If there is only one Anti-DDoS instance in the first hour, its cost is fully covered by the Anti-DDoS Basic plan.

    • If there are two Anti-DDoS instances in the second hour, their costs are fully covered by the Anti-DDoS Basic plan.

    • If there are three Anti-DDoS instances in the third hour, the Anti-DDoS Basic plan covers the costs for two instances, and the excess instance is billed on a pay-as-you-go basis.

Fixed monthly quota

Outbound data transfer plan

A fixed quota is provided every month. The quota resets on the first day of the next month. The remaining quota cannot be carried over to the next month.

For example, you purchase a one-month, 100 GB outbound data transfer plan on the 18th of the current month. The plan can cover 100 GB of outbound traffic over the Internet from the 18th to the end of the month. Any excess usage is billed on a pay-as-you-go basis. The quota resets on the 1st of the next month. From the 1st to the 18th of the next month, the plan can again cover 100 GB, and any excess usage is billed on a pay-as-you-go basis.

Total declining balance

Transfer acceleration plan

The quota is deducted based on actual consumption until the balance is zero or the plan expires.

For example, if you purchase a 5 TB plan for three months, you have a total quota of 5 TB for transfer acceleration traffic over the three months. Any excess usage is billed on a pay-as-you-go basis.

Deduction regions

When you purchase an OSS resource plan, you must specify a region, except for Anti-DDoS Basic plans. A region-specific resource plan can cover costs only in the specified region.

Note

An Anti-DDoS Basic plan can cover charges in any region where Anti-DDoS instances can be enabled. However, within the same hour, it can cover charges for only a single instance in a single region. If you incur Anti-DDoS charges in multiple regions within the same hour, you must purchase additional Anti-DDoS Basic plans to cover the charges.

Region type

Description

Global

Covers usage costs for corresponding resources in all regions. Can be shared across regions.

Region-specific①

Covers usage costs for corresponding resources in a specific region. Cannot be shared across regions.②

Universal for the Chinese mainland①

Covers usage costs for corresponding resources in multiple regions within the Chinese mainland. Can be shared across regions.③

Transfer acceleration region

Covers upload and download acceleration traffic costs when accessing OSS in different regions from different regions through an acceleration endpoint.

Transfer acceleration M2M

Covers upload and download acceleration traffic costs (AccM2MIn, AccM2MOut) when accessing OSS within the Chinese mainland from the Chinese mainland through an acceleration endpoint.

Transfer acceleration M2O_O2M

Covers upload and download acceleration traffic costs (AccM2OIn, AccM2OOut, AccO2MIn, AccO2MOut) when accessing OSS in the Chinese mainland from outside the Chinese mainland, or vice versa, through an acceleration endpoint.

Transfer acceleration O2O

Covers upload and download acceleration traffic costs (AccO2OIn, AccO2OOut) when accessing OSS outside the Chinese mainland from outside the Chinese mainland through an acceleration endpoint.

① You can purchase a universal resource plan for the Chinese mainland and a region-specific resource plan for a region in the Chinese mainland at the same time. When costs are deducted, the region-specific plan is used first. If the quota of the region-specific plan is exhausted, the universal plan is used. Any remaining usage is billed on a pay-as-you-go basis.

② For example, a resource plan for China (Qingdao) can cover usage costs only for corresponding resources in the China (Qingdao) region. It cannot cover costs for resources in other regions.

③ For information about the regions in the Chinese mainland that are supported by universal resource plans, see Regions supported by universal plans for the Chinese mainland.

① Purchase multiple resource plans of the same type. When you stack multiple resource plans of the same type, the one that expires first is used first. For example, on February 1, 2022, you purchase a one-year, 1 TB universal outbound data transfer plan for the Chinese mainland. On March 1, 2022, you purchase another three-month, 1 TB universal outbound data transfer plan for the Chinese mainland. In this case, the plan purchased on March 1, 2022, is used first.
