# Architecture

Quilt data packages are reproducible, discoverable, and trusted data sets that live in blob storage.

A package manifest includes both *metadata* and physical keys to primary data.

All package metadata and data are stored in your S3 buckets. A slice of the package-level metadata, as well as S3 object contents, are sent to an ElasticSearch cluster managed by Quilt. All Quilt package manifests are accessible via SQL using AWS Athena.
