Object Storage Service:Billing overview

Storing data in OSS incurs a storage fee based on duration. Each upload, download, or access incurs a request fee, and public internet distribution incurs outbound data transfer fees. Value-added services such as CDN acceleration, image processing, Transfer Acceleration, and DDoS protection generate additional billable items.

If your workload has predictable usage, purchase a resource plan to reduce costs. A resource plan must precisely match the billable item it covers. For example, a data transfer plan offsets only outbound data transfer fees. A mismatched plan will not apply to your bill.

Billable items

OSS has two categories of billable items:

• Basic billable items: Common charges for most OSS users, including the storage fee for stored data, outbound data transfer fees for downloads or CDN distribution, and the request fee for read and write requests.

• Billable items for value-added services: Optional services such as image processing, Transfer Acceleration, and DDoS protection. Billable items for value-added services.

Billing methods

OSS supports two billing methods:

• Pay-as-you-go: A post-paid method where you pay for actual usage of each billable item. Ideal for workloads with fluctuating usage.

• Resource plans: A pre-paid method. Purchase resource plans for common billable items such as storage and outbound data transfer to receive a discount. Usage is first deducted from the plan; excess usage is billed on a pay-as-you-go basis. Suitable for workloads with stable usage.

Free tier

First-time OSS users are eligible for a free tier that provides a certain amount of Standard (LRS) storage capacity at no charge.

Billing cycle

OSS meters resource usage and calculates fees on an hourly basis.
