HNREL06-BP01 Use multiple data centers for physical location redundancy

Connect from multiple geographically separate data centers or colocation sites to cloud for true physical location redundancy. Use dynamically routed, Active/Active connections across these sites to enable automatic load balancing and failover.

Desired outcome: Ensure network connectivity to cloud remains available even if one location experiences an outage or disaster.

Level of risk exposed if this best practice is not established: High

Benefits of establishing this best practice:

  • Eliminates single points of failure at the physical site level

  • Enables business continuity and disaster recovery

  • Supports high availability and compliance requirements

  • Improves resilience to disasters or unplanned events

Implementation guidance

  • Deploy dedicated connections from at least two geographically distinct facilities.

  • Use dynamic routing BGP for automatic failover.

  • Test failover regularly to validate resiliency.
