Traffic Fees

Last updated: 2021-04-25 15:54:34

    Traffic fees are calculated based on the accumulated traffic generated by downloading the data stored.

    Traffic generated by data transfer from the client to COS over the Tencent Cloud private network Free
    Private network downstream traffic Traffic generated by data transfer from COS to the client over the Tencent Cloud private network Free
    Public network upstream traffic Traffic generated by data transfer from the client to COS over the Internet Free
    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 a Tencent Cloud CDN edge server 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 among buckets in the same region will not incur traffic fees.
    Pay-as-you-go
    Global acceleration traffic Traffic generated by data transfer using an acceleration endpoint through the global acceleration feature. This traffic consists of upstream traffic and downstream traffic:
  • Upstream traffic is the traffic generated by uploading data to COS using an acceleration endpoint.
  • Downstream traffic is the traffic generated by viewing or downloading COS data using an acceleration endpoint.
  • Pay-as-you-go

    Note:

    Tencent Cloud products within the same region will access each other over the private network by default and no traffic fees will be incurred. For more information on how to identify private network access, please see COS Access via the Private Network and the Public Network.

    Billing Restrictions

    1. ARCHIVED data cannot be read or downloaded until it is restored to the STANDARD storage class. Therefore, traffic generated from these requests is counted in the STANDARD storage class.
    2. Public network downstream traffic is generated when the data is returned to COS through origin-pull using a third-party CDN service.
    3. After CDN acceleration is enabled, CDN origin-pull traffic is generated when a user browses or downloads COS data on the client through a Tencent Cloud CDN acceleration endpoint.
    4. Public network downstream traffic is generated when a user downloads objects through object links or browses objects through a static website endpoint.
    5. Cross-region replication traffic is generated when you replicate data from a bucket in one region to a bucket in another region using APIs or the cross-region replication feature. The traffic fees will vary depending on the region where the source bucket resides.
    6. For INTELLIGENT TIERING, traffic fees are subject to those of the storage class after object movement.

    Traffic Direction

    The figure below shows the traffic fees incurred by data transmitted from COS to an end user with the Tencent Cloud CDN acceleration endpoint enabled and disabled, respectively.

    Note:

    CDN traffic fees are charged by Tencent Cloud CDN. For detailed pricing, please see CDN Pricing.

    Billing Method and Calculation Formulas

    Billing Method Applicable Billable Items Calculation Formula
    Pay-as-you-go
  • Public downstream traffic fees
  • CDN origin-pull traffic fees
  • Cross-region replication traffic fees
  • Global acceleration traffic fees
  • Daily billing cycle
  • Traffic fees = Unit price per GB x Daily accumulated traffic
  • Billing Example

    Note:

    • Prices in the example below are for reference only. For the actual prices, please see COS Pricing.
    • 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.

    Example: STANDARD storage fees + STANDARD request fees + Public downstream traffic fees

    Assume that on November 1, 2020, user A uploaded a 10 GB object to a bucket residing in the 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 a public network with CDN disabled. Apart from these operations, user A did not perform any other operations in November. As storage 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:

    • STANDARD storage fees = 0.024 USD/GB/month x 10 GB = 0.24 USD
    • STANDARD request fees = 0.002 USD/10,000 requests x 10,000 requests = 0.02 USD
    • Public downstream traffic fees = 0.1 USD/GB x 10 GB x 2 = 2 USD

    In summary, the total bill for user A in November is calculated as follows: 0.24 + 0.02 + 2 = 2.26 USD.
