• App: production
• Semester: semester-08-system-design-leadership
• Module: module-03-event-driven-architecture
• Unit kind: concept
• Curation level: module_curated

Learning objectives

• Explain The Shift from CRUD to Events in terms of events, temporal coupling, and consistency tradeoffs instead of diagram-first messaging vocabulary.
• Use The Shift from CRUD to Events to predict how data, retries, ordering, and observability will behave when workflows are split across asynchronous boundaries.
• Use fundamentals-of-software-architecture, system-design-primer to connect the learner explanation to streams, event contracts, choreography, and coordination failure modes.

Prerequisites

• Comfort with service decomposition, distributed communication, and consistency tradeoffs from the earlier modules.
