Does COS have a free tier?

We provide new COS users with a free tier of standard storage capacity with a validity period of 6 months. For more information, see Free Tier.

How is COS billed?

The fees of COS are broken down into five items: storage capacity, requests, data retrievals, traffic, and management Feature Fees.

For information on billable items in COS and billing rules, see Billing Restrictions.

Why is my account still in arrears (fees are deducted) even if I am entitled to the free tier?

Possible reasons include:

  1. Other billable items: COS fees are charged for storage, requests, data retrievals, traffic, and management Feature Fees. Currently, the free tier is only applicable to standard storage, while other billable items will be billed as incurred.
  2. Charges for excessive use of resources. For example, if you are entitled to 50 GB of free standard storage capacity, but your actual storage exceeds 50 GB, the excessive storage will be billed as incurred.
  3. Expiration of the free tier. We provide new COS users a free tier of standard storage capacity with a validity period of 6 months. After the expiration of the free tier, storage will be billed as incurred. You can log in to the COS Console to view the validity period for your free tier on the subscription plan management page.

How can I check my bills?

You can view information about the fees incurred by COS in the Billing Center in the console. For more information, see Viewing Billing Details.

Will fees be charged for requests and traffic generated by data transfer between COS and CVM?

No fees will be charged for traffic that is generated by data transfer between COS and CVM in the same region as the transfer is over the private network. For more information on how to identify private network access, see How to determine an access via private network. If your COS and CVM services are in different regions, the traffic will be billed.

All requests generated by data transfer between CVM and COS will be billed.

How is the public network downstream traffic in COS billed?

Public network downstream traffic is traffic generated by data transfer from COS to the client over the internet. Traffic generated by downloading an object directly through an object link or by browsing an object through a static website access node is public network downstream traffic. For more information on billing for such traffic, see Billing Restrictions and Product Pricing.

How is the CDN origin-pull traffic in COS billed?

CDN origin-pull traffic is traffic generated by data transfer from COS to a CDN edge server. After CDN acceleration is enabled, traffic generated by browsing or downloading COS data in the client is CDN origin-pull traffic. For more information on billing for such traffic, see Billing Restrictions and Product Pricing.

Will traffic fees be incurred by uploading a file to a COS bucket?

No.

Will traffic fees be incurred when Tencent Cloud products in the same region access each other?

Tencent Cloud products in the same region access each other over the private network by default and no traffic fees will be incurred. For more information, see How to determine an access via private network.

If my account is in arrears and COS service is suspended, can I still access and download files in the COS Console?

If your COS service is suspended because your account is in arrears, you have no access to the console. Your data will be retained for 120 days. If you fail to top up your account to a positive balance within this period, your data will be destroyed. For more information, see Arrears.

Will traffic fees be incurred when the objects stored in COS are under DDoS attacks?

DDoS attacks on objects do not incur traffic fees. COS buckets come with hotlink protection, which can reduce the impact of DDoS attacks. For more information, see Setting Hotlink Protection.
