A deployment target site is a logical grouping of one or more servers that serve the same content. When you deploy to a target site, every server in the target is updated to reflect the new set of assets.

If multiple data stores mirror each other, you can group them in a single target site in order to synchronize their content. Alternatively, you can put them in different targets, so one cluster remains functional in case the other has deployment problems. In either case, a workflow can specify only one target site per deployment. For example, if the workflow defines staging and production deployments, it can identify just one target site for each deployment.

Note: A repository where you deploy assets can have reference constraints to tables from another repository only if both repositories belong to the same target.
