• App: production
• Semester: semester-08-system-design-leadership
• Module: module-02-microservices-service-decomposition
• Unit kind: concept
• Curation level: module_curated

Learning objectives

• Explain Synchronous REST/gRPC vs Asynchronous Events as a boundary and coordination problem, not a default move toward more services.
• Use Synchronous REST/gRPC vs Asynchronous Events to reason about coupling, ownership, deployment cost, and operational complexity in a real organization.
• Use fundamentals-of-software-architecture, system-design-primer to connect the learner page to decomposition strategies, data ownership, and service collaboration tradeoffs.

Prerequisites

• Comfort with structured system-design thinking and the cost of architectural boundaries from module 01.
