Multi-Datacenter Deployments

Zenoh's topology freedom enables true geo-distributed deployments where data flows seamlessly between datacenters, edge sites, and field devices.

Architecture Pattern

Multi-datacenter topology

Router Configuration for Geo-Distribution

// DC Router (US East)
{
  mode: "router",
  listen: {
    endpoints: ["tls/0.0.0.0:7447"],
  },
  connect: {
    // Connect to EU datacenter
    endpoints: ["tls/dc-eu.example.com:7447"],
  },
  routing: {
    router: {
      region: "us/east",
    },
  },
}

Failover

Zenoh handles link failures transparently. If the transatlantic link drops:

  • Local traffic continues uninterrupted within each region
  • Reconnection is automatic when the link recovers
  • Subscribers receive data from the nearest available source (with storage)

Recommended Reading

  • Storages — persist data at each tier
  • Security — encrypt inter-datacenter links with mTLS
