What are the data replication strategies for availability?
Data replication strategies for availability include synchronous replication, where data is written to multiple nodes simultaneously, ensuring zero data loss during failures. Asynchronous replication prioritizes speed by delaying updates to secondary nodes, suitable for geographically distributed systems. Multi-master replication allows multiple nodes to accept writes, improving fault tolerance. Hybrid approaches combine synchronous for critical data and asynchronous for non-critical. Cloud providers use zone-aware replication to distribute data across availability zones, ensuring high uptime and disaster recovery.
