Replication Sydney → Auckland

Overview

Publish only to the Sydney primary. Cross-Region ReplicationCross-Region Replication
Cross-Region Replication. S3 copies objects (and versions) from a primary bucket to a replica in another Region.
copies matching keys to Auckland. Consumers there use the replica URL: same key, different hostname.

Both buckets need versioning on. S3 Replication will not enable without it.

Source	Primary ap-southeast-2
Destination	Replica ap-southeast-6
Prefix filter	demo/
Versioning	Enabled on both buckets

Notes

• Replication is async. demo.sh publish waits until the replica answers HeadObject.
• Because versioning is on, teardown has to delete all versions (and delete markers) before the buckets can go away.
• The replica needs its own Auckland VPCE on the allowlist.
