Regions & Zones

As described in the Reference Architecture, we recommend spreading your Nest Instances and Machines across different failure domains. You model this topology as Regions and Zones.

A Zone is a failure domain, such as a rack or a data center. A Region is a group of Zones close to each other, such as the data centers of one city.

Once set up, you can assign Machines and Nest Instances to a Zone. Their nodes then get two labels:

Label	Value
topology.kubernetes.io/region	The name of the Region
topology.kubernetes.io/zone	The name of the Zone
