There are no set up charges or commitments to begin using S3 Express One Zone. S3 Express One Zone charges you for storage and requests. The volume of storage billed in a month is accrued based on total storage used per hour, measured in gigabyte per month (GB-Month). You are also charged a per request fee for access based on the request type—such as PUTs and GETs. You will pay an additional per-GB fee for data upload and retrieval. Example 1:
Assume you store 10 GB of data in S3 Express One Zone for 30 days, making a total of 1,000,000 writes and 9,000,000 reads, accessing with Athena with a request size of 10 KB. Then, you delete 1,000,000 files by the end of 30 days. Assuming your bucket is in the US East (Northern Virginia) Region, the storage and request charges are calculated below: Storage Charges
Total Byte-Hour usage = 10 GB-Month
Total Storage cost = 10 GB-Month x $0.11 = $1.10 Request Charges
1,000,000 PUT Requests: 1,000,000 requests x $0.00113/1,000 = $1.13
9,000,000 GET Requests: 9,000,000 requests x $0.00003/1,000 = $0.27
1,000,000 DELETE requests = 1,000,000 requests x $0.00 (no charge) = $0 Data upload charge: 10 KB / 1,048,576 x 1,000,000 x $0.0032 = $0.03
Data retrieval charge: 10 KB / 1,048,576 x 9,000,000 x $0.0006 = $0.05
Total Charges = $1.10 + $1.13 + $0.27 + $0.03 + $0.05= $2.58 Example 2:
Assume you store 10 TB of data for machine learning training for an 8-hour workload every day, and then delete it. During the 8-hour workload you make 5,242,880 writes and 10,485,760 reads for a 2 MB request size. Assume you do this for 30 days (a month). Storage Charges
Total Byte-Hour usage = [10,995,116,277,760 bytes x 30 days x (8 hours / day)] = 2,638,827,906,662,400 Byte-Hours = 3303.77 GB-Month
Total Storage cost = 3303.77 GB x $0.11 = $363.41 Request Charges
5,242,880 PUT Requests/day: 5,242,880 requests x 30 x $0.00113/1,000 = $177.73
10,485,760 GET Requests/day: 10,485,760 requests x 30 x $0.00003/1,000 = $9.44
5,242,880 DELETE requests/day: 5,242,880 requests x $0.00 (no charge) = $0 Data upload charge: 2MB/1024 x 5,242,880 x 30 x $0.0032 = $983.04
Data retrieval charge: 2MB/1024 x 10,485,760 x 30 x $0.0006 = $368.64
Total Charges = $363.41 + $177.73 + $9.44 + $983.04 + $368.64 = $1,902.26
