Security, Identity, and Access Control

Security becomes a different kind of problem once a serverless system starts to grow into a real distributed application. OrderProcessor is no longer just a set of Functions reacting to requests and events. It now has multiple entry points, long-running workflows, external integrations, and operational boundaries that all need to be protected consistently. In that sort of system, security cannot sit in one login screen or one shared secret. It has to be carried across the whole platform, from HTTP endpoints and orchestration triggers to downstream API calls, secrets, network paths, and audit evidence.
