How SBB brings cloud to on-prem & runs critical apps on AWS Outpost
summary
SBB builds a platform called Halon that runs critical rail workloads on AWS Outpost racks using CDK + TypeScript to compile to CloudFormation, EKS/OpenShift worker nodes on Outpost, and an event messaging backbone; architecture uses two geographically separated Outposts (active/active design with active/passive application failover), DVR/local gateway networking for single‑digit‑millisecond latency, 16 infrastructure stacks across ~13 repos, and automated pipelines — deployed in production and proving repeatable and resilient.
