HNREL06-BP02 Ensure service continuity with redundant hardware and diverse telecommunications providers
Implementing redundant hardware components across geographic locations, organizations can mitigate single points of failure that threaten critical workloads. This resilience strategy should extend beyond computing resources to include diverse telecommunications providers, creating independent network paths that remain operational even when regional carriers experience outages. The combination of hardware redundancy and carrier diversity creates a robust foundation that enables businesses to maintain operations through localized disruptions, ensuring that customers experience minimal service interruptions and that service level agreements remain intact despite infrastructure challenges.
Desired outcome: Reduce risk of connectivity loss due to hardware or carrier failures, maintaining consistent hybrid network availability.
Level of risk exposed if this best practice is not established: High
Benefits of establishing this best practice:
-
Increases fault tolerance and uptime
-
Minimizes downtime from single hardware or carrier outages
-
Supports disaster recovery planning
-
Helps meet or exceed AWS and provider SLA commitments
Implementation guidance
-
Use separate network devices and cables for each connection.
-
Engage more than one telecom provider with diverse paths for "last mile" connections.
-
Periodically review and test infrastructure and SLAs.
