Purchase OSS resource plans

Billing Item Detection Tool

Use the Billing Item Detection Tool to view the storage, request, traffic, and transfer acceleration usage generated by OSS. Purchase resource plans based on the recommendations.

For example, suppose that the current account has Standard (ZRS) storage billable items in two regions, and the charge reason is No eligible resource plan has been purchased for this billing item. The region details for China (Hangzhou) show approximately 1.82 GB of Standard (ZRS) storage usage over the last three days. Based on the recommendation, purchase a Standard (ZRS) storage plan.

Analyze bills

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

• Match by billable item: If standard zone-redundant storage capacity is the primary cost shown on your bill, purchase a Standard (ZRS) Storage Plan to offset the cost.

• Match by usage: If your bill shows 40 GB of storage capacity per hour, purchase a 40 GB Standard (ZRS) Storage Plan to precisely cover the actual usage.

  Request charges are calculated based on the request fee rules.

The resource plan names on the purchase page map to the names in this topic as follows:

• Request - Standard storage classon the purchase page corresponds to Request plan-Standard storagein this topic.

• Request - Non-standard storage classon the purchase page corresponds to Request plan-storage class other than Standardin this topic.

  The region option on the purchase page is Chinese mainland and does not distinguish individual regions.

Purchase a single resource plan

Purchase the resource plan that corresponds to the billable item identified by the detection tool or in your bill.

Before you purchase, note the following:

• Resource plan type — You cannot change the resource plan type after purchase. A resource plan can offset only charges for its corresponding billable items, not all charges. Select an appropriate resource plan type when you make the purchase.

• Cold Archive (LRS) capacity — A Cold Archive (LRS) storage plan, which uses locally redundant storage, has a minimum capacity of 500 TB.

1. Log on to the OSS console.

2. In the left-side navigation pane, choose Resource Usage > Resource Plan Management.

3. On the Resource Plan Management page, click Purchase Resource Plan. You can also go directly to the OSS resource plan purchase pageto make a purchase.

4. Select the resource plan type, region, capacity, duration, and other parameters based on your requirements. Then, click Buy Now.

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

   A resource plan takes effect immediately after purchase and automatically offsets the corresponding billable items. You do not need to establish a connection manually.

Purchase a data distribution and processing bundle resource plan

For image processing, video transcoding, format conversion, and content distribution scenarios, purchase a data distribution and processing bundle resource plan. The plan can offset billable items for Object Storage Service (OSS) and Intelligent Media Management (IMM).

Storage plan deduction scope

Standard (ZRS) Storage Plan can offset Standard (LRS) storage capacity charges but cannot offset the storage capacity used by ECS snapshots.

For additional resource plan types and deduction scopes, see Resource plan overview and selection.

Annual subscription discounts

The longer the subscription duration, the lower the average monthly unit price of the resource plan. The following examples use Standard (LRS) storage plans:

• 100 GB: A monthly subscription costs CNY 11 per month, or CNY 132 for a full year. An annual subscription costs CNY 99, which saves approximately 25% compared with the monthly price for a full year.

• 40 GB: A six-month subscription costs CNY 4.98. An annual subscription costs CNY 9, which saves approximately 9.6% compared with two six-month subscriptions.

Compare resource plans and pay-as-you-go

The following table compares the cost of a resource plan and the pay-as-you-go billing method for 100 GB of Standard (LRS) storage:

An annual resource plan saves approximately 31% compared with pay-as-you-go.

Select a billing method based on your business stage. In the early stage, when usage is low — for example, less than 100 GB of storage and less than 100 GB of outbound traffic — use the pay-as-you-go billing method. You pay only for actual usage and avoid wasting unused resource plan capacity. When your business stabilizes and usage consistently exceeds 100 GB of storage and 100 GB of outbound traffic, purchase resource plans of the appropriate type and capacity to reduce the unit cost.

Select capacity and duration

Resource plans of different capacities support different subscription durations, and some capacities are available only with specific durations. Before you purchase a plan, confirm the durations available for the required capacity on the Purchase Resource Plan page, and select the best combination based on your expected usage.

A Cold Archive (LRS) storage plan has a minimum capacity of 500 TB. If the capacity that you need is unavailable, see the FAQ section of this topic.

What if I purchased the wrong resource plan?

If the resource plan you purchased does not meet your expectations, select a solution based on the number of days since purchase and whether the plan has been used.

• OSS resource plan unused within five days of purchase — Request a full refund. After the refund is complete, purchase the correct resource plan.

• OSS resource plan used, or unused for more than five days after purchase — Select one of the following solutions based on the deduction method of the purchased resource plan.

For a partial refund, the refund amount is calculated as follows: Refund amount = Amount paid - (Original order price / Actual number of purchased days) × Number of days used.

For full-refund and partial-refund procedures, see Resource plan refund.

What if the desired resource plan capacity is unavailable?

OSS resource plans are typically available in capacities such as 100 GB, 500 GB, 1 TB, and 10 TB. If a resource plan with your required capacity, such as 9 TB, is unavailable, select a purchase method for a custom capacity. For most resource plans, the method depends on whether the resource plan supports combination.

• Resource plans that support combination — For resource plans such as outbound data transfer plans, purchase multiple plans to obtain 9 TB of capacity. For example, purchase one 5 TB plan and two 2 TB outbound data transfer plans.

• Resource plans that do not support combination — For resource plans such as Standard (LRS) Storage Plan, use one of the following methods:

  • Purchase a 10 TB Standard (LRS) Storage Plan.

  • Purchase a 5 TB Standard (LRS) Storage Plan. Use pay-as-you-go for the remaining capacity.

• Cold Archive (LRS) storage plans — A Cold Archive (LRS) storage plan, which uses locally redundant storage, has a minimum capacity of 500 TB. Cold Archive is suitable for data that is accessed extremely infrequently, and data retrieval takes several hours. If you require less than 500 TB for cold data, use one of the following options:

  • Use pay-as-you-go. You are charged based on actual usage and do not need to purchase a resource plan. After a resource plan expires, pay-as-you-go applies by default.

  • Purchase an Archive (LRS) storage plan, which starts at 100 GB.

  Resource plans that can be combined are listed in Supported resource plan operations.

Why doesn't the capacity increase after I renew a resource plan?

Renewing a monthly subscription resource plan, such as an outbound data transfer plan, extends only the validity period and does not increase the remaining capacity for the current month. On the first day of each month, the system automatically resets the capacity to the full amount. If the remaining capacity for the current month is insufficient, purchase an additional resource plan. The system automatically uses the new resource plan capacity based on the deduction rules.

Do I need to migrate data after an OSS resource plan expires and I purchase a new one?

No. Resource plans are used only to offset charges and do not involve data storage. After a resource plan expires, the data in your bucket remains in place and is not lost or made inaccessible because of the expiration. A new resource plan takes effect immediately after purchase and automatically offsets eligible storage charges.
