Scalable Cross-Region Disaster Recovery Models for Ensuring High Availability

This session explores scalable cross-region disaster recovery (DR) models for maintaining high availability in modern cloud data platforms. It evaluates active-active, active-passive, and hybrid architectures using a simulation-based framework, analyzing key metrics such as Recovery Time Objective (RTO), Recovery Point Objective (RPO), availability, and cost.

The findings highlight critical trade-offs: active-active models offer near-zero downtime but high complexity and cost, while active-passive and hybrid approaches are more cost-efficient but introduce recovery delays and potential data inconsistency. The study emphasizes the need for adaptive, workload-aware DR strategies rather than one-size-fits-all solutions.

The topic is highly relevant in today’s world, where geopolitical conflicts and incidents such as the destruction of data centers during the recent war in the middle east demonstrate the importance of resilient, geographically distributed cloud infrastructure for ensuring business continuity.

By the end of this session, attendees will be able to:

- Understand the fundamentals of cross-region disaster recovery and its role in ensuring high availability in distributed cloud systems

- Differentiate between active-active, active-passive, and hybrid architectures, including how they operate under failure conditions

- Analyze key disaster recovery metrics such as Recovery Time Objective (RTO) and Recovery Point Objective (RPO), and interpret their impact on system performance and business continuity

- Evaluate trade-offs between cost, latency, consistency, and operational complexity when selecting a disaster recovery strategy

- Apply practical insights to design resilient, scalable cloud architectures capable of handling real-world disruptions, including large-scale outages and infrastructure failures
