Romana is a cloud-native networking solution that automates the creation of isolated networks and implements distributed firewall capabilities for containerized and virtualized environments. The platform provides topology-aware IP Address Management (IPAM) that assigns natively routable IP addresses to endpoints without requiring network overlays or tunnels. This approach eliminates the performance overhead typically associated with overlay networking while simplifying network operations. The distributed firewall component applies access control policies consistently across all endpoints, including pods and virtual machines, regardless of their location within the infrastructure. Security policies are enforced at the endpoint level, providing granular control over network traffic. Romana's topology-aware address assignment enables highly aggregated routing within the network, which reduces the computational load on networking hardware and supports more secure network configurations. The system integrates with both Kubernetes and OpenStack orchestration platforms. The solution supports deployment across on-premises infrastructure and Amazon Web Services (AWS) environments, providing flexibility for hybrid and multi-cloud architectures.
