Alternatives
Skipped on purpose
Section titled “Skipped on purpose”| Approach | Why not |
|---|---|
| Transit Gateway Syd↔Akl | Too much cost and plumbing for object GET |
| Cross-Region PrivateLink to Syd S3 | Not available for ap-southeast-6 as of Sep 2026; check again before relying on it (lab findings) |
| One Syd bucket + remote readers | Cross-island transfer on every download |
| CloudFront / public bucket | Not private |
| S3 interface VPCE instead of gateway | Extra cost for same-Region S3 |
Other options (not this lab)
Section titled “Other options (not this lab)”- HTTPS to a regional app (for example Pulp) when you need yum indexes, not plain objects.
- A second regional publisher if replication lag is a problem.
- CI
createrepo_c+ sync if you later put static yum trees on these buckets.
