From Orchestration to Choreography, from Practice to Theory
summary
A concrete code kata that implements the same workflow first as centralized orchestration and then as event-driven choreography, demonstrating trade-offs with real code and cloud deployment. The demo moves tests from direct method calls to an in-memory bus, then to Azure Event Grid and Azure Functions, adds correlation IDs, a capture store and a control-tower supervision job, and shows that adding a notification service requires changing two places under orchestration but only one with choreography; the system is run in production and incurs real cloud costs.
