Resilient Multi-Region Service Design: Failover, Data Consistency, and Disaster Recovery

Abstract

Author(s): Yara Evans, David Gonzalez, Mei Singh. This study explores resilient multi-region service design: failover, data consistency, and disaster recovery with a focus on practical engineering trade-offs in modern cloud-native environments. We present an implementation-driven methodology, reference architectures, and evaluation criteria that teams can adopt in reliability engineering programs. Results highlight measurable improvements in reliability, security posture, and end-user performance when the proposed practices are applied.
