Learning objectives
- Explain Service Contracts: Sync APIs, Async Events, Tolerant Readers as a boundary and coordination problem, not a default move toward more services.
- Use Service Contracts: Sync APIs, Async Events, Tolerant Readers to reason about coupling, ownership, deployment cost, and operational complexity in a real organization.
- Use
fundamentals-of-software-architecture,system-design-primerto 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.
