# Redundancy Zones
<EnterpriseAlert>
This feature requires
self-managed Consul Enterprise.
Refer to the{' '}
<a href="/docs/enterprise#consul-enterprise-feature-availability">enterprise feature matrix</a>
for additional information.
</EnterpriseAlert>
Consul Enterprise redundancy zones provide
both scaling and resiliency benefits by enabling the deployment of non-voting
2020-04-06 20:27:35 +00:00
servers alongside voting servers on a per availability zone basis.

When using redundancy zones, if an operator chooses to deploy Consul across 3 availability zones, they
could have 2 (or more) servers (1 voting/1 non-voting) in each zone. In the event that a voting
member in an availability zone fails, the redundancy zone configuration would automatically
promote the non-voting member to a voting member. In the event that an entire availability
zone was lost, a non-voting member in one of the existing availability zones would promote
to a voting member, keeping server quorum. This capability functions as a "hot standby"
for server nodes while also providing (and expanding) the capabilities of
2020-04-09 23:20:00 +00:00
[enhanced read scalability](/docs/enterprise/read-scale) by also including recovery
2020-04-06 20:27:35 +00:00
capabilities.
