Example Concept: A multi-region failover strategy typically uses DNS-based routing with services like AWS Route 53 or Azure Traffic Manager to direct traffic across regions. Data replication is crucial, often achieved with managed database services that support cross-region replication. Infrastructure as Code (IaC) tools, such as Terraform, can automate the deployment of identical environments in multiple regions. Health checks and monitoring are essential to detect failures and initiate failover processes, ensuring minimal downtime and data loss.
