Cross-account disaster recovery setup using AWS Elastic Disaster Recovery in secured networks (Part 2: Failover and failback implementation)

This article provides a detailed guide for implementing cross-account disaster recovery using AWS Elastic Disaster Recovery in secured network environments. The second part of a two-part series focuses on the failover and failback implementation process.

• Covers installation of AWS replication agent using VPC endpoints
• Demonstrates how to perform recovery drills while preserving IP addresses
• Explains reverse replication process between production and recovery regions
• Provides step-by-step instructions for failback and protecting new production servers
• Highlights key benefits including enhanced security, business continuity, and regulatory compliance

The solution enables organizations to maintain strict security controls during disaster recovery while supporting bidirectional replication between AWS accounts and regions, all within a private network infrastructure.
