Managing digital asset representation of physical assets in IoT systems and environments. A digital twin is created, tracked, and modified throughout the physical asset's lifetime using a digital registry having a data record including a unique identifier (optionally encrypted) and a storage device location information for the digital twin. A physical tag is coupled to the physical asset and scanned for read and write operations from and to the digital twin. The digital twin can move to a new storage device across a cloud environment and the registry maintains consistent access.
