Billable items

Important

You are not charged for the traffic that is generated by requests for which HTTP status code 4xx or 5xx is returned.

Billable item	Billing rule	Billing cycle	Billing method
Outbound traffic over the Internet (NetworkOut)	Traffic that is generated when data is transferred from OSS to the client over the Internet.	You are billed on an hourly basis. Bills are generally generated after a billing cycle ends. The time when bills are generated is determined by the system.	Pay-as-you-go: Traffic fees = Outbound traffic over the Internet × per-GB price for the current tier. Resource plan: Go to the OSS Resource Plan page and select Outbound Traffic Plan.
Inbound traffic over the Internet	Traffic that is generated when data is transferred from the client to OSS over the Internet.		Free of charge.
Outbound traffic over the internal network	Traffic that is generated when data is transferred from OSS to the client over the internal network. For more information about how to use internal endpoints, see Access OSS over the internal network.		Free of charge.
Inbound traffic over the internal network	Traffic that is generated when data is transferred from the client to OSS over the internal network.		Free of charge.
Origin traffic (CdnOut)	Traffic that is generated when data is transferred from OSS to Alibaba Cloud CDN points of presence (POPs).		Pay-as-you-go: Traffic fees = Total origin traffic (GB) × Unit price per GB. Resource plan: not supported. Note If you use both OSS and Alibaba Cloud CDN, the public endpoints of OSS are used. In this case, data is transferred over the Internet by default.
CRR traffic (ReplicationDatasize)	Outbound traffic that is generated when you use CRR to synchronize data from a source bucket to a destination bucket.		Pay-as-you-go: Traffic fees = Total CRR traffic (GB) × Unit price per GB. Resource plan: not supported.
