Nomad models infrastructure into regions and datacenters. Servers reside at the regional layer and manage all state and scheduling decisions for that region. Regions contain multiple datacenters, and clients are registered to a single datacenter (and thus a region that contains that datacenter). For more details on the architecture of Nomad and how it models infrastructure see the architecture page.

There are multiple strategies available for creating a multi-node Nomad cluster:

  1. Manual Clustering
  2. Automatic Clustering with Consul
  3. Cloud Auto-join

Please refer to the specific documentation links above or in the sidebar for more detailed information about each strategy.
