Digital Twins are a mechanism for simplifying IoT solution development.
For Eclipse Ditto the Digital Twin is a concept for abstracting a real world asset/device with all capabilities and aspects including its digital representation.
A Digital Twin
- mirrors physical assets/devices
- provides aspects+services around devices
- keeps real and digital worlds in sync
- can be applied in both industrial and consumer-centric IoT scenarios
In the IIoT the Digital Twin metaphor is becoming a popular concept for tracking a produced product/good in its complete lifecycle.
