Microsoft's  Azure Digital  Twins service, used to model physical  environments via software for planning purposes, is now generally available over two years after being released as a preview. 
Microsoft's partners, such as buildings technology  company Johnson  Controls, are already using the Azure Digital Twins service. Johnson  Controls has its own OpenBlue Digital Twin platform that works with Azure  Digital Twins to assess things like energy use in buildings, workspace  optimization, safety and workflows within a facility. 
Another partner is software company Ansys,  which is using Azure Digital Twins to offer "physics-based simulation  models" for its customers. Azure Digital Twins is also being used directly  by real-estate companies to model their properties. 
Azure Digital Twins is used to model a physical  environment in software, but Microsoft's solution also tracks any changes made  to those physically mapped areas. Typically, sensors in rooms are used to  provide the data. The sensors might send information such as room temperature  or occupancy, for instance. Azure Digital Twins can be used to plan outdoor  environments, as well. 
Azure Digital Twins has its own Digital Twins Definition Language (DTDL) for use by  developers. Microsoft is bringing DTDL to the Digital Twins Consortium, a  nonprofit trade group that Microsoft "cofounded" in May. 
The Azure Digital Twins service works with the Azure IoT  Hub, a service for managing Internet of Things (IoT) devices. Other Azure Digital  Twins components include a spatial intelligence graph for tracking people,  places and devices, role-based access controls for administrators, and notifications  and routing capabilities. 
Azure Digital Twins can be used with other Azure services,  such as Azure Data Lake for storage or Azure Synapse Analytics for data  analytics. It's possible to add capabilities "such as 3D or 4D  visualizations, physics-based simulation, and AI" on top of Azure Digital  Twins, Microsoft's announcement explained.
The "digital twins" name isn't wholly original.  It derives from the product manufacturing world, where duplicate or twin products  are built for testing purposes.
