Traffic is the accumulated value of data traffic generated when you use and access COS, including public network upstream traffic, public network downstream traffic, private network upstream traffic, private network downstream traffic, and CDN origin-pull traffic. COS charges you by the accumulated traffic usage.
For more information on storage classes, see Storage Class Overview.
|Billable Item||Applicable Storage Class||Description||Applicable Billing Mode|
|Private network upstream traffic||INTELLIGENT TIERING
|Traffic generated by data transfer from the client to COS over the Tencent Cloud private network||Free of charge|
|Private network downstream traffic||Traffic generated by data transfer from COS to the client over the Tencent Cloud private network||Free of charge|
|Public network upstream traffic||Traffic generated by data transfer from the client to COS over the internet||Free of charge|
|Public network downstream traffic||Traffic generated by data transfer from COS to the client over the internet||Pay-as-you-go|
|CDN origin-pull traffic||Traffic generated by data transfer from COS to CDN edge node||Pay-as-you-go|
|Cross-region replication traffic||Traffic generated by replicating objects from a bucket in one region to a bucket in another region
Note: Replicating objects across buckets in the same region will not incur traffic fees.
|Global acceleration traffic||Traffic generated by data transfer at an acceleration endpoint through the global acceleration feature. This traffic consists of upstream traffic and downstream traffic:
If the global acceleration domain name is used to download data, global acceleration downstream traffic fees and public network downstream traffic fees will be incurred. If the global acceleration domain name is used as the CDN origin domain name for origin-pull, global acceleration downstream traffic fees and CDN origin-pull traffic fees will be incurred.
After you enable the CDN acceleration domain name, data downloads and access through it will incur fees:
|CDN origin-pull traffic||Origin-pull traffic generated by data transfer from COS to the CDN edge node when COS is used as the CDN origin.|
|CDN traffic||CDN outbound traffic generated by data download from the CDN edge node to the local system or client when COS is used as a CDN origin.|
|COS request||COS requests generated by data transfer from COS to the CDN edge node when COS is used as the CDN origin. Request fees are billed by the number of requests sent to COS.|
CDN traffic fees are charged by CDN. For detailed pricing, see Pricing | Content Delivery Network.
|Billing Mode||Applicable Billable Items||Calculation Formula|
For the unit prices of traffic, see Pricing | Cloud Object Storage.
- Prices in the example below are for reference only. For the actual prices, see Pricing | Cloud Object Storage.
- The minimum number of requests for billing is 10,000. Therefore, if the number of monthly accumulated requests is less than 10,000, you will still be billed for 10,000 requests, regardless of whether the request succeeds or fails.
Assume that on November 1, 2020, user A uploaded a 10 GB object to a bucket residing in Guangzhou region in the STANDARD storage class, generating 100 requests. On November 2 and November 3, user A downloaded the object to the local file system over the public network with CDN disabled. Apart from these operations, user A did not perform any other operations in November. As storage usage fees and request fees are calculated on a monthly basis, they will be billed on December 1, 2020. Traffic fees are calculated on a daily basis and will thus be billed on November 3 and November 4, 2020. The fees are calculated as follows:
In summary, the total bill for user A in November is calculated as follows: 0.24 + 0.02 + 2 = 2.26 USD.
