Digital Twin Patterns

When to use

Designing a digital twin architecture from scratch (shadow vs twin vs simulation)
Modeling twin ontologies with DTDL, RealEstateCore, or custom schemas
Implementing device-to-twin and twin-to-device synchronization pipelines
Building predictive maintenance with RUL models and anomaly detection
Running what-if scenario analysis in a sandboxed twin environment
Selecting Azure Digital Twins, AWS IoT TwinMaker, or open-source alternatives

Core principles

Maturity determines complexity — start with a digital shadow (read-only), graduate to bidirectional twin only when control use cases are proven
Graph topology mirrors physical topology — site → building → floor → room → device; queries follow the physical hierarchy
Eventual consistency is fine for monitoring; not for control — sub-second twin updates matter only in closed-loop control scenarios
Staleness thresholds are a first-class feature — a twin that hasn't updated in 5x its expected interval is broken, not just quiet
Sandbox before touching the physical asset — all what-if scenarios run on a cloned twin state, never against the live twin
