Full title and description
St ISO IEC 21823-1-2019 — Information technology — Internet of Things (IoT) — Architecture — Part 1: Reference architecture. This standard defines a high-level, vendor-neutral reference architecture for IoT systems, providing concepts, building blocks, component relationships and architectural viewpoints to support interoperable IoT solutions across domains.
Abstract
This document presents a reference architecture for the Internet of Things (IoT). It describes architectural building blocks, their responsibilities and interactions, core concepts (things, gateways, services, data, management), and cross-cutting concerns such as security, privacy and manageability. The reference architecture is intended to guide solution design, enable interoperability and support conformance assessment across heterogeneous IoT deployments.
General information
- Status: Published standard
- Publication date: 2019
- Publisher: Joint ISO/IEC (International Organization for Standardization / International Electrotechnical Commission)
- ICS / categories: 35.020 (Information technology) — Internet of Things / system architecture
- Edition / version: First edition (2019)
- Number of pages: Approximately 30–50 pages (typical for a Part 1 architectural specification)
Scope
The scope of this part is to provide a platform-neutral, high-level reference architecture for IoT systems that supports cross-domain interoperability. It covers architectural viewpoints, functional building blocks, interfaces and interactions, plus non-functional requirements such as security, privacy, scalability and manageability. It is not a prescriptive implementation specification; rather it serves as a common conceptual framework for designers, vendors, integrators and standards developers.
Key topics and requirements
- Definition of core architectural building blocks (things/devices, gateways, network, data services, application services, management).
- Reference viewpoints and layers to separate concerns (device, edge/gateway, network, platform/cloud, application).
- Interoperability principles and interface patterns to enable cross-vendor integration.
- Security and privacy considerations across the architecture (identity, authentication, authorization, secure communication, data protection).
- Manageability and lifecycle support (provisioning, firmware/software updates, diagnostics, monitoring).
- Data modelling and semantics to support information exchange and integration.
- Guidance on scalability, resilience and quality-of-service aspects for IoT deployments.
- Conformance and testing considerations to help assess implementations against the reference model.
Typical use and users
This standard is used by system architects, solution designers, product vendors, system integrators, test laboratories and standards bodies. It is helpful when planning and designing IoT platforms, ensuring interoperability between devices and services, creating procurement requirements, and mapping domain-specific architectures to a common reference framework.
Related standards
Related and complementary standards typically referenced alongside this part include other parts of the ISO/IEC 21823 series (other part numbers addressing interfaces, data models or conformance), ISO/IEC standards addressing IoT reference architectures and security, and sector- or protocol-specific standards (for example IoT data/semantic standards, network and telecommunications standards, and industry domain standards). Use this part as the high-level architecture reference and combine with protocol- and domain-specific standards for implementation-level guidance.
