However, most data is not replicated between regions as they are fully independent clusters. The exceptions are [ACL tokens and policies][acl], as well as [Sentinel policies in Nomad Enterprise][sentinel], which *are* replicated between regions. Nomad server clusters in different datacenters can be federated using WAN links. The server clusters can be joined to communicate over the WAN on port `4648`. This same port is used for single datacenter deployments over LAN as well. @@ -129,3 +129,6 @@ In the event of a region-level failure (which would contain an entire Nomad serv - Read [Deployment Guide](/guides/install/production/deployment-guide.html) to learn the steps required to install and configure a single HashiCorp Nomad cluster. + +[acl]: /guides/security/acl.html +[sentinel]: /guides/governance-and-policy/sentinel/sentinel-policy.html
