Azure Digital Twins is a Microsoft Azure platform for creating digital representations of real-world environments. It models the relationships between physical entities — buildings, machines, rooms, and sensors — as a live graph. This lets engineers run complex queries and analytics across an entire environment. EPC Group implements Azure Digital Twins for IoT, smart building, and industrial clients. 29 years of Microsoft experience.
Key Facts
- Azure Digital Twins models physical environments as a property graph of interconnected nodes.

- Supports complex relational queries: "find all rooms above 80°F where HVAC is running."
- Integrates with Azure IoT Hub, Azure Event Hubs, Azure Data Explorer, and Power BI.
- Pricing: per message, per query, and per digital twin. Free tier available for development.
- EPC Group: 29 years Microsoft consulting, 10,000+ enterprise deployments.

What is Azure Digital Twins?
Azure Digital Twins is a platform for building live digital representations of physical environments. Every physical entity becomes a node in a graph.
A building model might include floors, rooms, HVAC zones, lighting systems, and occupancy sensors. All nodes connect by relationships. That lets you run queries like: "Which rooms on the third floor are occupied but have HVAC set to unoccupied mode?"
This relational context transforms raw sensor data into actionable operational intelligence. It spans the entire environment — not just individual sensors in isolation.
How Azure Digital Twins Works
Azure Digital Twins uses three core concepts:
- Digital Twin Definition Language (DTDL) — A JSON-based language for defining models. You describe what properties, telemetry, relationships, and commands each entity type supports.
- Twins — Instances of a model. A DTDL "room" model spawns one twin per physical room. Each twin holds live property values updated from IoT sensors.
- Relationships — Connections between twins. A "room" twin relates to a "floor" twin. A "sensor" twin relates to the "HVAC zone" it monitors. Relationships make cross-entity queries possible.
Key Features
- Graph-based queries — Azure Digital Twins Query Language lets you traverse relationships and filter by live property values.
- Live data ingestion — IoT Hub or Event Hubs streams sensor telemetry directly into twin property updates.
- Event routing — Route twin property changes to downstream services: Azure Functions, Event Hubs, Logic Apps, or Power BI.
- Azure Data Explorer integration — Archive historical twin property data for time-series analytics and trend analysis.
- 3D visualization — Azure Digital Twins Explorer provides a visual graph browser for model management and debugging.
- REST API and SDKs — .NET, Java, JavaScript, and Python SDKs for custom application integration.
Common Use Cases
- Smart buildings — Monitor HVAC, lighting, occupancy, and energy in real time. Run automated responses when rooms exceed comfort or energy thresholds.
- Manufacturing — Model factory lines, machines, and work cells. Detect upstream bottlenecks before they halt production.
- Energy and utilities — Model grid topology. Detect faults and run load-balancing queries across distribution networks.
- Healthcare facilities — Track medical device locations, room occupancy, and environmental conditions for patient safety and compliance.
- Supply chain — Model warehouses, shipment containers, and logistics assets with live GPS and sensor updates.
Azure Digital Twins Pricing
Azure Digital Twins pricing is based on three dimensions:
- Messages — Charged per 1,000 messages (property updates or telemetry ingested).
- Queries — Charged per query unit. Simple queries use fewer units. Complex multi-hop relationship traversals use more.
- Digital twins — Charged per 1,000 digital twins stored in the graph.
Development environments with low twin counts and low message volume fit within the Azure Digital Twins free tier. Production environments scale pricing with the number of twins and message frequency. Use the Azure pricing calculator for an accurate estimate based on your twin count and message rate.
Security for Regulated Environments
Azure Digital Twins supports compliance-first deployments. Key security controls:
- Azure Entra ID authentication — Role-based access control (RBAC) for all twin read and write operations.
- Private endpoints — Isolate Digital Twins from the public internet using Azure Private Link.
- Managed identities — Authenticate downstream services (Azure Functions, Event Hubs) without stored credentials.
- Encryption — All data encrypted at rest and in transit. Customer-managed keys available via Azure Key Vault.
For highest-security workloads, Azure Confidential Computing uses AMD SEV-SNP and Intel TDX enclaves to protect data while it is in use. This covers workloads where even the host operator must not be able to inspect the data — clinical analytics, M&A modeling, and federal IL5.
Frequently asked questions
What is Azure Digital Twins?
Azure Digital Twins is a Microsoft platform for creating live, graph-based digital representations of physical environments. It models entities like rooms, machines, and sensors as connected nodes. Engineers run relational queries across the entire graph to detect conditions and trigger automated responses.
What is DTDL?
DTDL stands for Digital Twin Definition Language. It is a JSON-based schema language for defining the models used in Azure Digital Twins. You use DTDL to describe what properties, telemetry, and relationships each entity type supports before creating twin instances.
How does Azure Digital Twins integrate with IoT Hub?
Azure IoT Hub routes device telemetry to an Azure Function. The function updates the corresponding digital twin's live properties. Changes to twin properties can then trigger events routed to Power BI, Event Hubs, or other downstream services.
How much does Azure Digital Twins cost?
Pricing has three components: messages (per 1,000), queries (per query unit), and twin storage (per 1,000 twins). Low-volume development environments fit within the free tier. Production pricing scales with twin count and message frequency. Use the Azure pricing calculator for an estimate.
What industries use Azure Digital Twins?
Smart buildings, manufacturing, energy and utilities, healthcare facilities, and supply chain. Any industry that needs to model and query relationships between physical assets in real time is a candidate for Azure Digital Twins.

Azure Architecture: 2026 Considerations for Azure Digital Twins Pricing Features Guide Creating Digital Representation
FinOps in Azure 2026 is no longer optional at any meaningful scale: Azure Reservations (1-yr or 3-yr commits) deliver 30-72% savings on predictable VM workloads, Azure Savings Plans extend the discount to compute portability across instance families, and Azure Hybrid Benefit lets BYOL Windows Server and SQL Server licenses cut compute costs by an additional 40-49%. Typical Azure cost-optimization engagements return 25-40% of annual Azure spend within 90 days.
Azure Confidential Computing (DCadsv5/ECasv5 series) is the privileged-data play for 2026: AMD SEV-SNP and Intel TDX enclaves protect data IN USE (in addition to at-rest and in-transit encryption), enabling regulated workloads (clinical analytics with PHI, financial services M&A modeling, federal IL5) to run on shared Azure infrastructure with cryptographic attestation that the host operator cannot inspect the data.
Decision factors EPC Group evaluates
- Azure Policy initiative assignment for Azure Government readiness
- Confidential Computing enclave evaluation for regulated workloads
- Enterprise-scale landing zone bootstrap via Bicep/Terraform
- Microsoft Defender for Cloud benchmark alignment
