Automate Upgrades with Consul Enterprise
Upgrade your Consul datacenters without downtime using automated upgrades. This functionally is provided through the Enterprise feature of autopilot. Autopilot allows you to add new servers directly to the datacenter and waits until you have enough servers running the new version to perform a leadership change and demote the old servers as "non-voters".
Provide Fault Tolerance with Redundancy Zones
Use Consul’s redundancy zones to provide high availability in the case of server failure through the Enterprise feature of autopilot. Autopilot allows you to add “non-voting” servers to your datacenter that will be promoted to the "voting" status in case of voting server failure.
