Object Storage Service:Purchase OSS resource plans

Last Updated:Dec 04, 2025

Lower your OSS costs for stable workloads by purchasing a resource plan. For example, if you anticipate your Standard (ZRS) storage usage to be approximately 100 GB over the next three months, we recommend purchasing a 100 GB Standard (ZRS) storage plan with a three-month term.

Step 1: Determine which resource plan to purchase

You can also select a suitable resource plan type and capacity based on the billable items and usage shown in your bills.

  • Match by billable item: If your bill shows that most of your costs are from Standard (ZRS) storage capacity, you can purchase a Standard (ZRS) Storage Plan to offset these charges.

  • Match by usage: For example, if your bill indicates an average hourly usage of 40 GB of storage capacity, you can purchase a 40 GB Standard (ZRS) Storage Plan to precisely cover your consumption.

Step 2: Purchase a resource plan

Purchase a resource plan that corresponds to the billable items identified in your bill.

  1. Log on to the OSS console.

  2. In the left-side navigation pane, select Resource Usage > Resource Plans.

  3. On the Resource Plans page, click Purchase Resource Plan.

  4. Select the resource plan type, region, capacity, and validity period based on your business requirements. Then, click Buy Now.

    Important
    • After purchasing a resource plan, you cannot change the resource plan type. A resource plan of a specific type can only be used to offset fees generated by billable items corresponding to the resource plan type. When purchasing a resource plan, select a suitable resource plan type.

    • A resource plan takes effect immediately after you purchase it. You do not need to manually establish a connection before fees for the corresponding billable items are automatically offset.

  5. Follow the on-screen instructions to complete the purchase.

    Description

    Fixed total amount

    • Standard (LRS) storage plan

    • IA (LRS) storage plan

    Request a partial refund.

    Refund amount = Paid amount - (Original price/Purchase duration in days) × used days.

    If you do not want to request a partial refund, you can convert the redundancy type of the bucket from LRS to ZRS, then use the ZRS plan to offset the corresponding storage capacity.

    After converting the redundancy type, you are charged based on ZRS instead of LRS. The price of ZRS is higher than that of LRS. For more information, see OSS pricing details.

What do I do if a resource plan of the desired capacity is not available on the buy page?

You can purchase resource plans with different capacities, such as 100 GB, 500 GB, 1 TB, and 10 TB, on the OSS buy page. If resource plans of specific capacities are not available, such as 9 TB, you can use one of the following methods to resolve the issue:

  • Resource plans that support combination

    For resource plans that support combination, such as outbound traffic plans, you can purchase multiple resource plans. For example, to purchase an outbound traffic of 9 TB, you can purchase one outbound traffic plan of 5 TB and two outbound traffic plans of 2 TB.

  • Resource plans that do not support combination

    For resource plans that do not support combination, such as Standard (LRS) storage plans, you can use one of the following methods to purchase a capacity of 9 TB:

    • Purchase a Standard (LRS) storage plan of 10 TB.

    • Purchase a Standard (LRS) storage plan of 5 TB and use the pay-as-you-go billing method for the excess 4 TB of storage capacity.

For information about resource plans that support combination, see Supported operations.
