# MIDAREL05-BP01 Design a multi-Region disaster recovery strategy
<a name="midarel05-bp01"></a>

 Manufacturing operations require high availability of systems that control production lines, inventory management, and supply chain logistics. A multi-Region disaster recovery strategy means that if one Region experiences an outage, manufacturing systems can continue operating from another region with minimal disruption. 

 **Desired outcome:** A resilient manufacturing environment that can quickly recover from regional failures, which improves continuous production capabilities, maintains access to critical manufacturing data, and minimizes operational downtime. 

 **Benefits of establishing this best practice:** 
+  Reduced production downtime during Regional outages. 
+  Protection of critical manufacturing data and systems. 
+  Maintained supply chain continuity. 
+  Improved compliance posture with industry regulations and customer SLAs. 
+  Enhanced business resilience against natural disasters or large-scale infrastructure failures. 

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

## Implementation guidance

+  **Implement data replication across Regions:** Set up continuous replication of manufacturing data, including ERP and MES systems and production databases using Amazon RDS Multi-AZ with cross-Region read replicas or Amazon S3 Cross-Region Replication. 
+  **Create automated recovery procedures:** Develop AWS CloudFormation templates or use AWS Elastic Disaster Recovery to automate the recovery of manufacturing applications and infrastructure components with predefined RTOs and RPOs. 
+  **Establish production monitoring and failover mechanisms:** Implement Route 53 health checks and failover routing policies to automatically redirect traffic to backup manufacturing systems in case of primary system failure. 
+  **Test DR procedures regularly:** Schedule periodic disaster recovery tests using AWS Fault Injection Service to validate that manufacturing operations can be recovered within defined time frames and that all production-critical systems function properly after recovery.
