Resiliency and DR

Reference architecture for enterprise disaster recovery with RTO/RPO tiers, storage replication, and automated failover patterns.

Operational practices and multi-site resiliency patterns for enterprise platforms including recovery tiers, failover models, and testing strategies.

Metro pair operating in active-active mode with synchronous replication, plus asynchronous replication to out-of-region warm standby for regional disaster recovery scenarios.

Primary site with warm out-of-region standby using asynchronous replication, providing regional survivability without multi-site active-active operational overhead.

Single active primary site with hypervisor/platform replication to recovery site, utilizing manual failover processes for workloads tolerating several hours RTO.

Backup-based recovery pattern with no continuous replication, focusing on recoverability through validated backups and redeployment processes for non-critical workloads.

Unified classification system for multi-site resiliency patterns with consistent terminology, RTO/RPO characteristics, and clear guidance for selecting appropriate models based on business requirements.

Metro active-active pattern with synchronous replication, delivering zero or near-zero RPO and sub-minute RTO for mission-critical workloads.
