Learning objectives

• Explain Deployment Independence: Versioning and Backward Compatibility as a boundary and coordination problem, not a default move toward more services.
• Use Deployment Independence: Versioning and Backward Compatibility 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.
