Shared Output Destinations

All members of a federation — every parcel and the shell — deploy into the same named output destination. The destination is backed by one of two transport types:

Folder

A directory on a local or shared file system. The composed site is served from that directory (or copied onward by your own process).

Amazon S3

An S3 bucket (optionally fronted by CloudFront). Uploads apply web-appropriate caching — versioned assets are cached immutably while pages and maps are always revalidated — and changed pages trigger a CloudFront invalidation when a distribution is configured.

For the steps to create Folder and Amazon S3 output destinations, see Creating Output Destinations.

Note: ePublisher never stores AWS access keys. S3 destinations record only the bucket, region, profile name, and distribution ID; credentials always resolve through the standard AWS profile or role chain on the machine that deploys.
