The 20th Anniversary of the UNIX® Standard and Certification

By The Open Group

The UNIX® platform, as a technology, has been around more than 40 years, being at the center of innovation and technology in computer science and driving the Fortune 1000 businesses today. Over twenty years ago, a number of companies came together to acknowledge the value of the UNIX platform, but more importantly, the need for all UNIX implementations to be interoperable and compatible to support the tremendous ecosystem built on top of UNIX systems. An open and inclusive collaboration followed, which led to the creation of the Single UNIX Specification, the industry standard for UNIX systems. The standard is supported by extensive certification tests to ensure that the theory of interoperability and compatibility became a reality with suppliers, vendors and customers knowing and demanding UNIX certification in their solution. UNIX, the go-to operating system, is trusted for mission critical applications because it is robust with a powerful footprint and is inherently more secure and stable than the alternatives. The first UNIX certifications were awarded twenty years ago this year.

During the following 20 years, the UNIX standard has continued to evolve and embrace new technology. The most recent version UNIX V7 is the latest step in the evolution of the standard, but by no means the end as there is greater and greater demand by those developing UNIX operating systems, those who integrate UNIX operating system in their solutions and, most importantly, the customers who deploy those solutions as part of their business innovation.

“The UNIX platform demonstrates the value of being open, since as a truly open standard it allows all to focus on driving innovation of the ecosystem around the platform rather than competing at the core OS level. The open standard makes portability easier for software developers, provides integrators with choice in the building blocks for solutions, and enables customers to focus on solving business problems rather than integration issues,” says Steve Nunn, President and CEO, The Open Group.

“The Open Group from day one has been the shepherd for the standard leveraging its long history in the development of open standards. This ensures the value of the standard UNIX platform grows for both member companies who contribute, as well as those who demand openness as part of their solution,” comments Andrew Josey, Director, Standards, The Open Group.

Please join The Open Group and our Platinum Member UNIX Partners in celebrating this momentous 20-year milestone.

Apple Registers Mac OS X 10.8 Mountain Lion to the UNIX® 03 Standard

By Andrew Josey, The Open Group

Today, Apple, Inc. released the latest version of the Mac OS X, version 10.8, also known as “Mountain Lion.” In addition to the product’s release, we are pleased to announce that Mac OS X Mountain Lion has achieved certification to The Open Group UNIX® 03 standard, which is the mark for systems conforming to the Single UNIX Specification, Version 3.

The Single UNIX Specification is an open specification that defines the set of required interfaces for a conformant UNIX system. Support for the Single UNIX Specification permits wide portability of applications between compliant and compatible operating systems. High reliability, availability and scalability are all attributes associated with certified UNIX® systems. By registering operating systems as compliant with the Single UNIX Specification, UNIX system suppliers assure their users of the stability, application portability and interoperability of their products.

Over the years, Apple has been a great supporter of the UNIX standard, and today, Mac OS X is the most widely used UNIX desktop operating system. Apple’s installed base—over 50 million users— and commitment to the UNIX standard as a platform is significant to the UNIX certification program. We look forward to continuing to work with Apple and our other UNIX partners in promoting open and interoperable operating systems as the specification continues to evolve.

Andrew Josey is Director of Standards within The Open Group. He is currently managing the standards process for The Open Group, and has recently led the standards development projects for TOGAF 9.1, ArchiMate 2.0, IEEE Std 1003.1-2008 (POSIX), and the core specifications of the Single UNIX Specification, Version 4. Previously, he has led the development and operation of many of The Open Group certification development projects, including industry-wide certification programs for the UNIX system, the Linux Standard Base, TOGAF, and IEEE POSIX. He is a member of the IEEE, USENIX, UKUUG, and the Association of Enterprise Architects.
