6.2.3. Geo-replication using standalone Red Hat Quay

Standalone Red Hat Quay geo-replication runs in multiple regions with a shared database and Redis and localized storage per region. Image pulls use the closest storage and pushes replicate in the background, improving performance for distributed users.

In the following image, Red Hat Quay is running standalone in two separate regions, with a common database and a common Redis instance. Localized image storage is provided in each region and image pulls are served from the closest available storage engine. Container image pushes are written to the preferred storage engine for the Red Hat Quay instance, and are then replicated in the background to the other storage engines.
