# AWS S3

> The API everything else copies, and by far the most expensive egress in this roster.

- Defines the interface, semantics and edge cases every other provider implements against
- Remains the most complete: storage classes, Object Lock, replication, Access Points, event notifications
- IAM condition keys nobody else matches
- At USD 0.09 per gigabyte, egress on a read-heavy workload costs more than everything else combined

Ranked **#11 of 12** on default weights.
| Field | Value | Confidence | Verified | Source | Note | Permalink |
| --- | --- | --- | --- | --- | --- | --- |
| True cost /mo (USD) | $472.6/mo | Inferred | 2026-07-23 | https://aws.amazon.com/s3/pricing/ | us-east-1, S3 Standard. Storage 1,000 GB x $0.023 = $23.00. Egress (5,000 - 100 free) GB x $0.09 = $441.00. PUT/LIST 1 M at $0.005/1,000 = $5.00. GET 9 M at $0.0004/1,000 = $3.60. Total $472.60, of which 93% is bandwidth. Egress stays inside AWS's first 10 TB band at 5 TB, so no tiering applies. In ap-southeast-2 (Sydney) the same workload is $592.20, see the Sydney column for that arithmetic. | https://toolweight.com/compare/s3-compatible-storage#aws-s3--true_cost_usd |
| True cost /mo (AUD) | A$718.35/mo | Inferred | 2026-07-23 | - | $472.60 x 1.52, a conversion of the us-east-1 bill. Run from Sydney it is a quarter higher again; the Sydney column has it. | https://toolweight.com/compare/s3-compatible-storage#aws-s3--true_cost_aud |
| True cost from Sydney (AUD) | A$900.14/mo | Inferred | 2026-07-23 | https://aws.amazon.com/s3/pricing/ | ap-southeast-2, S3 Standard. Storage 1,000 GB x $0.025 = $25.00. Egress (5,000 - 100 free) GB x $0.114 = $558.60. PUT/LIST 1 M at $0.005/1,000 = $5.00. GET 9 M at $0.0004/1,000 = $3.60. Total $592.20 x 1.52 = A$900.14. Sydney egress is 27% dearer per gigabyte than us-east-1, which on this workload is most of the difference. | https://toolweight.com/compare/s3-compatible-storage#aws-s3--sydney_cost_aud |

**Verdict.** Still the most capable object store, and thirty-eight times Hetzner's cost here, almost entirely bandwidth.
