Zero-Downtime Multi-Region Cloud Deployment with Kubernetes & Terraform

# Zero-Downtime Multi-Region Cloud Deployment In high-concurrency enterprise environments, even 5 minutes of unexpected downtime can result in massive revenue loss and customer dissatisfaction. ## Infrastructure as Code (Terraform) By declaring 100% of cloud resources in version-controlled Terraform modules, staging and production environments remain completely synchronized. - **Automated Failover**: Multi-region AWS EKS clusters connected via CloudFront route traffic away from unhealthy regions automatically. - **Canary Releases**: Deploying new code to 5% of users before full rollout prevents breaking changes from affecting all accounts.
