YugabyteDB offers a distributed SQL database built on PostgreSQL, allowing for high availability and disaster recovery capabilities with its xCluster DR feature. By deploying primary and secondary clusters across multiple regions in Microsoft Azure, users can achieve an RPO of 1ms and an RTO of just a few seconds for cloud-native PostgreSQL deployments. The xCluster DR simplifies recovery from unplanned outages or planned switchover, enabling seamless failover and switchover processes while maintaining data integrity.
