Implementation guidance

DRHCREL02-BP01 Provision redundant power and network to on-premises components

To ensure high availability for AWS Outposts deployments, implement redundant power sources and network connectivity while considering multi-Outpost distribution across different Availability Zones.

Desired outcome: Achieve high availability of on-premises systems, helping to provide consistent data access and processing capabilities in compliance with data residency requirements.

Benefits of establishing this best practice: Redundant power and network infrastructure improves the reliability and availability of on-premises components, minimizing potential downtime.

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

Outpost Racks are designed with redundant power and networking equipment. Customer racks will house individual Outposts servers. To meet high availability objectives, we recommend providing dual power sources and redundant network connectivity to Outposts and customer racks.

Implementation guidance

  • Provide dual power sources to Outposts and Customer racks.

  • Provision redundant network connectivity (for example, redundant network devices) to Outposts.

  • For higher availability, deploy applications on multiple Outposts, each attached to a different Availability Zone, to build additional application resilience and avoid dependence on a single Availability Zone.
