Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that are
members of ISO or IEC participate in the development of International Standards through technical
committees established by the respective organization to deal with particular fields of technical
activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other international
organizations, governmental and non-governmental, in liaison with ISO and IEC, also take part in the
work. In the field of information technology, ISO and IEC have established a joint technical committee,
ISO/IEC JTC 1.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject
of patent rights. ISO and IEC shall not be held responsible for identifying any or all such patent
rights. Details of any patent rights identified during the development of the document will be in the
Introduction and/or on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.

assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/IEC JTC 1, Information technology, Subcommittee
SC 38, Cloud Computing and Distributed Platforms.
ISO/IEC 18384 consists of the following parts, under the general title Reference Architecture for Service
Oriented Architecture (SOA RA):
— Part 1: Terminology and Concepts for SOA
— Part 2: Reference Architecture for SOA Solutions
— Part 3: Service Oriented Architecture Ontology

Introduction
Service oriented architecture (SOA) is an architectural style in which business and IT systems are
designed in terms of services available at an interface and the outcomes of these services. A service is a
logical representation of a set of activities that has specified outcomes, is self-contained, and it may be
composed of other services but consumers of the service need not be aware of any internal structure.
SOA takes “service” as its basic element to constitute and integrate information systems so that they are
suitable for a variety of solution requirements. SOA enables interactions between businesses without
needing to specify aspects of any particular business domain. Using the SOA architectural style can
improve the efficiency of developing information systems, and integrating and reusing IT resources.
In addition, using the SOA architectural style can help realize agile and rapid response of information
systems to ever-changing business needs.
This International Standard describes a single set of SOA technical principles, specific norms,
and standards for the world-wide market to help remove confusion about SOA and improve the
standardization and quality of solutions.
This International Standard defines the terminology, technical principles, reference architecture, and
the ontology for SOA. The targeted audience of this International Standard includes, but is not limited
to, standards organizations, architects, architecture methodologists, system and software designers,
business people, SOA service providers, SOA solution and service developers, and SOA service
consumers who are interested in adopting and developing SOA. For example, this part of ISO/IEC 18384
can be used to introduce SOA concepts and to guide to the developing and managing SOA solutions.
This International Standard contains three parts:
a) ISO/IEC 18384-1 which defines the terminology, basic technical principles and concepts for SOA;
b) ISO/IEC 18384-2 which defines the detailed SOA reference architecture layers, including a
meta
