去年9月份cloudflare推出了r2存储内测，现在已正式开放测试，主打免流量传输费用和s3兼容API。只按请求数量和存储容量收费，当其他家还在计费流量时土豪CF又一次站在了对象存储的前沿说明界面。
收费如下：
Pricing
R2 charges based on the total volume of data stored, along with two classes of operations on that data:
- Class A operations which are more expensive and tend to mutate state.
- Class B operations which tend to read existing state.
There are no charges for egress bandwidth.
All included usage is on a monthly basis.

| Free | Paid - Rates | |
|---|---|---|
| Storage | 10 GB / month | $0.015 / GB-month |
| Class A Operations | 1,000,000 requests / month | $4.50 / million requests |
| Class B Operations | 10,000,000 requests / month | $0.36 / million requests |

Storage is billed using gigabyte-month (GB-month) as the billing metric. A GB-month is calculated by recording total bytes stored for the duration of the month.
For example:
- Storing 1 GB for 30 days will be charged as 1 GB-month.
- Storing 2 GB for 15 days will be charged as 1 GB-month.

Class A Operations include ListBuckets, PutBucket, ListObjects, PutObject, CopyObject, CompleteMultipartUpload, CreateMultipartUpload, UploadPart, and UploadPartCopy.

Class B Operations include HeadBucket, HeadObject, and GetObject.

Free operations include DeleteObject, DeleteBucket and DeleteMultipartUpload.

If a user writes 1,000 objects in R2 for 1 month and each object is 1 GB in size and requested 1,000 times per month, the estimated cost for the month would be:
| Usage | Free Tier | Billable Quantity | Price | |
|---|---|---|---|---|
| Class B Operations | (1,000 objects) * (1,000 reads per object) | 10,000,000 | 0 | $0.00 |
| Class A Operations | (1,000 objects) * (1 write per object) | 1,000,000 | 0 | $0.00 |
| Storage | (1,000 objects) * (1GB per object) | 10 GB-months | 990 GB-months | $14.85 |
| TOTAL | $14.85 |

If a user writes the same 1 GB object 1,000,000 times a day and the object is read 10,000,000 times a day, the estimated cost in a month would be:
| Usage | Free Tier | Billable Quantity | Price | |
|---|---|---|---|---|
| Class B Operations | (1 object) (10,000,000 reads per day) (30 days) | 10,000,000 | 290,000,000 | $104.40 |
| Class A Operations | (1 object) (1,000,000 writes per day) (30 days) | 1,000,000 | 29,000,000 | $130.50 |
| Storage | (1 object) * (1GB per object) | 10 GB-months | 0 GB-months | $0.00 |
| TOTAL | $234.90 |
