Disaster recovery in distributed systems ensures resilience by protecting against failures in complex, distributed environments. This presentation will explore essential strategies like replication, redundancy, and failover mechanisms that help preserve availability and data integrity. We will examine the trade-offs between synchronous and asynchronous replication, the importance of automatic failover, and the challenges of ensuring consistency in the context of the CAP theorem. A hands-on example will also be provided to illustrate these concepts in practice.
