Enterprise Case Studies in Serverless Distributed Systems

Earlier chapters introduced the foundations piece by piece: durable orchestrations, messaging patterns, observability, security, deployment, governance, and operational resilience. Those chapters established the building blocks, but real systems rarely present those concerns one at a time. In practice, enterprise systems combine them. A single workflow may involve large file uploads, external partners, tenant-specific rules, regional compliance boundaries, human approvals, and long-running integrations, all while still needing to remain observable, secure, and resilient.
