Cover image for Designed a complete multi-region private

Designed a complete multi-region private cloud architecture using OpenNebula across three geographically separated regions with a total of 20 physical servers. The solution provides centralized cloud management, regional workload isolation, secure inter-region connectivity, shared cloud services, disaster recovery, backup replication, and dedicated monitoring for the complete infrastructure. The environment was structured as follows: Primary Region: 8 servers Secondary Region: 8 servers Disaster Recovery and Expansion Region: 4 servers Centralized OpenNebula management and scheduling KVM-based virtualization across all compute nodes Regional firewalls, routers, load balancers, and gateway services Separate compute, storage, management, tenant, replication, and monitoring networks Shared storage and Ceph-based storage architecture Cross-region backup replication and workload failover Centralized image, template, user, network, and lifecycle management Secure administrator and tenant access through SSO and role-based access control A dedicated monitoring and observability environment was also designed separately from the production cloud network. The monitoring stack included Prometheus or Zabbix for metrics collection, Grafana for dashboards, Alertmanager for notifications, and Loki or the ELK Stack for centralized log management. Regional monitoring proxies and agents collect host, VM, storage, application, and network metrics from each region while keeping the monitoring infrastructure isolated from tenant and production traffic. The architecture was designed to provide: High availability across multiple regions Centralized private cloud management Secure workload and tenant isolation Disaster recovery and regional failover Scalable compute and storage capacity Centralized monitoring, logging, and alerting Infrastructure automation through APIs, Terraform, Ansible, and CI/CD pipelines This project demonstrates my ability to design secure, scalable, highly available private cloud platforms using OpenNebula, KVM, software-defined networking, distributed storage, infrastructure automation, and enterprise monitoring technologies.
