You are separately charged for each Object Storage Service (OSS) service. For example, you are charged storage fees when you store objects in OSS, fees for outbound traffic over the Internet when you access objects stored in OSS over the Internet, and data processing fees when you use Image Processing (IMG) to process the images you store in OSS. This topic describes the billable items and billing methods of OSS.
OSS calculates all resource usage each hour and charges fees for actual usage.
- Pay-as-you-go: OSS calculates and charges fees for actual usage. You can complete the payment after the bill arrives. Fees are calculated based on the following formula: Fees = Actual usage × Unit price per hour. For more information, see Pay-as-you-go.
- Subscription: You can use resources only after you purchase resource plans. Resource plans are used to deduct fees charged when you use resources in each billing cycle. For more information, see Overview.
