Lightbridge VNA

Lightbridge is a "Build in Public" project to replace legacy, monolithic VNAs with a modern, scalable, and cost-effective architecture.

It is a cloud-native Vendor Neutral Archive (VNA) built on Kubernetes. The project deploys an enterprise-grade DICOM engine (Orthanc) and Object Storage abstraction (MinIO) to AWS in minutes via Terraform.
