An interactive IoT-A reference architecture workbench for exploring Virtual Entity abstraction, architecture views, cross-cutting concerns, deployment bindings, and stakeholder traceability.
IoT-A ARM Virtual Entity Architecture views Traceability

Trace one IoT-A design across every architecture view.

Pick a system pressure and watch the same asset become a Physical Entity, Virtual Entity, service contract, deployment binding, and operational responsibility. The useful habit is keeping those views connected without treating the reference model as a literal product stack.

Domain view: name the real-world thing before naming services.

A Physical Entity is the real-world object of interest. A Virtual Entity is the digital representation that lets applications reason about it without binding directly to every sensor.

Step 1 of 6
IoT-A architecture view explorer An interactive diagram tracing physical entities, devices, resources, virtual entities, services, applications, deployment nodes, and operations through IoT-A views.
82% View coverage

Core views are connected with minor operational gaps.

360 Physical bindings

Devices and resources remain behind a stable Virtual Entity contract.

16 Service contracts

Services expose resources and VE state without direct device coupling.

Medium Review risk

Security, privacy, trust, and management are visible but need evidence.

Architecture diagnosis

The current model separates real-world assets from digital representations, which keeps applications stable when devices change.

    IoT-A terms
    • Physical Entity: the real-world object that matters to the system.
    • Device: the technical artifact that senses, actuates, stores, or communicates.
    • Resource: software or compute hosted on a device that exposes capability.
    • Virtual Entity: the digital representation that applications can query.
    Technical accuracy notes

    IoT-A is a reference architecture and method for structuring concerns. It does not mandate MQTT, CoAP, cloud services, gateway counts, latency budgets, or a vendor product stack. This page uses simplified counts to show coupling and traceability pressure.

    Architecture review prompts
    • Can every Virtual Entity be traced back to physical devices and resources?
    • Does the Information View define attributes, units, ownership, and freshness?
    • Do security, privacy, trust, and management appear across the views, not only at the end?
