DRHCOPS03-BP04 Implement failover automation, and test your disaster recovery strategies

Implement failover automations, and validate the automations through ongoing tests. Verify that your automation adheres to the boundaries of the data residency requirements.

Desired outcome: Automate the failover process and regularly test disaster recovery strategies to validate their effectiveness and identify potential gaps or areas for improvement.

Benefits of establishing this best practice: Implement failover automation and conducting periodic testing of disaster recovery strategies verifies that recovery plans are reliable, up to date, and can be run efficiently, minimizing downtime and data loss in the event of an actual disaster scenario.

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

Implementation guidance

Failover automation

Implementing failover automation to maintain availability during outages or disasters:

  • Failover within the boundaries of your data residency requirement.

  • Use AWS services like AWS Lambda, Amazon CloudWatch, and AWS Systems Manager to automate failover processes between Outposts, Local Zones, and AWS Regions. AWS Elastic Disaster Recovery Service might also be an option for failovers between Outposts to Region or Outposts and on-premises workloads. 

  • Implement scripts or tools to automate the failover of workloads, reducing manual intervention and meeting RTO targets.

Testing and validation

  • Regularly test and validate your disaster recovery strategies, including failover and failback processes, to verify that they meet your RTO and RPO targets.

  • Identify and address any bottlenecks or issues that may impact recovery times or data loss.
