Nomad supports multi-datacenter and multi-region configurations. A single region is able to service multiple datacenters, and all servers in a region replicate their state between each other. In a multi-region configuration, there is a set of servers per region. Each region operates independently and is loosely coupled to allow jobs to be scheduled in any region and requests to flow transparently to the correct region.
When ACLs are enabled, Nomad depends on an "authoritative region" to act as a single source of truth for ACL policies and global ACL tokens. The authoritative region is configured in the [`server` stanza](/docs/agent/configuration/server.html) of agents, and all regions must share a single a single authoritative source. Any ACL policies or global ACL tokens are created in the authoritative region first. All other regions replicate ACL policies and global ACL tokens to act as local mirrors. This allows policies to be administered centrally, and for enforcement to be local to each region for low latency.

Global ACL tokens are used to allow cross region requests. Standard ACL tokens are created in a single target region and not replicated. This means if a request takes place between regions, global tokens must be used so that both regions will have the token registered.
