Architecting Resilience- Cloud Disaster Recovery Explained
System outages and data loss events present existential threats to modern IT infrastructure. Traditional, on-premises disaster recovery (DR) solutions require massive capital expenditure and redundant hardware that often sits idle for most of its lifecycle. Cloud-based disaster recovery, or Disaster Recovery as a Service (DRaaS), shifts this paradigm by utilizing scalable, cutting-edge cloud infrastructure to ensure continuous operations. By moving DR to the cloud, organizations achieve unprecedented flexibility and cost-efficiency. This article provides comprehensive, expert insights into the mechanics of cloud-based disaster recovery. We will examine deployment architectures and failover optimization so you can stay ahead of the curve when designing resilient systems. The Mechanics of Cloud-Based Recovery Cloud disaster recovery operates on the principle of continuous or scheduled replication. Legacy tape backups are obsolete in high-availability environments. Instead, mo...
