EVALUATING OPEN SOURCE OPERATING SYSTEMS:

FEATURES, FLEXIBILITY, AND PERFORMANCE
White Paper June 2009
Abstract
The operating system is the foundation of an enterprise’s IT architecture. When evaluating open-source and proprietary OS solutions, more and more enterprises are recognizing the advantages of the easy access, continuous innovation, and flexibility that open source provides. Fortoday’s demanding enterprise, however, Sun’s Solaris™ and OpenSolaris™ operating systems provide the ideal strategic platform. While open source offers distinct advantages, Solaris and OpenSolaris provide unmatched features, flexibility, performance, and reliability for the enterprise.

Executive Summary

Sun Microsystems, Inc.Executive Summary
The operating system (OS), a collection of programs that serves as the interface between the hardware and the applications running on that hardware, can have a huge impact on how successfully enterprises meet their challenges. The OS manages all the other programs the enterprise uses as well as the allocation and use of hardware resources such as the CPU, memory, and harddisk drive. As a critical component of any IT solution, the choice of OS has both business and technical value for an enterprise. Enterprises now have the option of choosing between open source and proprietary OS solutions. This white paper explores the advantages of open-source OS’s and examines Sun’s open-source Solaris and OpenSolaris OS’s, which offer cross-platform capabilities andground-breaking features to improve performance, availability, and scalability.

Why open source for operating systems?
Open-source OS’s present a low-cost, secure, highly interoperable contrast to proprietary systems. The open-source model for OS development spurs innovation beyond the four walls of a company, in sharp contrast to the high-cost, high-maintenance, proprietary development approach behindsystems like Microsoft Windows, AIX, or HP-UX. Opensource OS licensing costs can be significantly lower than their closed-source equivalents, especially for customers wanting a full-featured distribution on high-end systems. Additionally, open-source OS’s that run on multiple platforms and work with a variety of applications from many sources make vendor lock-in less likely — and companies withspecial needs can customize specific open-source OS modules.
