The Identity of Things: Architecting Machine-First Security in the Sky Computing Era

As healthcare systems move toward cloud-agnostic “Sky Computing,” traditional human-centric security models break down. This article argues that machine identity—secured through workload identity federation, service meshes, short-lived tokens, and Python-based drift detection—is the new security perimeter. By replacing static keys with dynamic identities and monitoring privilege creep, healthcare architects can build interoperable, zero-trust ecosystems resilient to modern cloud-native threats.
