+# Nomad Enterprise Advanced Autopilot
+
+Nomad Enterprise supports Advanced Autopilot capabilities which enable fully
+automated server upgrades, higher throughput for reads and scheduling, and hot
+server failover on a per availability zone basis. See the sections below for 
+additional details on each of these capabilities. 
+
+* **Automated Upgrades:** Advanced Autopilot enables an upgrade pattern that 
+allows operators to deploy a complete cluster of new servers and then simply wait 
+for the upgrade to complete. As the new servers join the cluster, server 
+introduction logic checks the version of each Nomad server. If the version is 
+higher than the version on the current set of voters, it will avoid promoting 
+the new servers to voters until the number of new servers matches the number of 
+existing servers at the previous version. Once the numbers match, Autopilot will 
+begin to promote new servers and demote old ones.
+
+* **Enhanced Read Scalability:** With Advanced Autopilot, servers can be 
+explicitly marked as non-voters. Non-voters will receive the replication stream 
+but will not take part in quorum (required by the leader before log entries can 
+be committed). Adding explicit non-voters will scale reads and scheduling without 
+impacting write latency.
+
+* **Redundancy Zones:** Advanced Autopilot redundancy zones make it possible to 
+have more servers than availability zones. For example, in an environment with 
+three availability zones it's now possible to run one voter and one non-voter in 
+each availability zone, for a total of six servers. If an availability zone is 
+completely lost, only one voter will be lost, so the cluster remains available. 
+If a voter is lost in an availability zone, Autopilot will promote the non-voter 
+to voter automatically, putting the hot standby server into service quickly.
+
+See the [Nomad Autopilot Guide](https://www.nomadproject.io/guides/cluster/autopilot.html)
+for a comprehensive overview of Nomad's open source and enterprise Autopilot features.
