Area of Focus

Bill Claybrook focuses on Linux - servers, cluster technology, desktop, and embedded - and Open Source Software. He researches, analyzes, and reports on the business and technical impact of Linux and Open Source Software in the supplier and end-user communities. He serves as a consultant to suppliers for product positioning, messaging, market analysis, and strategy.

Current Research

Linux is the fastest growing operating system in the computer industry. The primary applications of Linux are in the Web server, file-and-print server, e-mail server, and firewall server areas. The suppliers of Linux have plans for Linux to move into the enterprise and be capable of supporting mission-critical applications. Claybrook's current research focuses on the required business support and technology to move Linux into the enterprise.

As a consultant, Claybrook advises companies on the type of open source license they should use to complement their business models and helps companies utilize the benefits of open source best practices in their own software development models. Claybrook also writes about the Open Source Software development business and the cluster technology available for Linux.

Recent Activity

Claybrook has written two Aberdeen White Papers - Linux for S/390: A Perspective for IT Executives and IBM Integrated Unix/Linux Operating System Strategy - that evaluates the value propositions for IBM Unix/Linux-based platforms and present the dynamics of the markets and how IBM has reacted to market changes.

He has written papers for OpenSales, Inc.; eGrail; and CollabNet describing how the best practices of open source software development are used to create products for the fast-paced, Internet-based economy.
