The book wraps up with a look at the legal effects--both positive and negative--of open source/free software licensing.

Open source software is changing the world of Information Technology. But making it work for your company is far more complicated than simply installing a copy of Linux. If you are serious about using open source to cut costs, accelerate development, and reduce vendor lock-in, you must institutionalize skills and create new ways of working. You must understand how open source is different from commercial software and what responsibilities and risks it brings. Open Source for the Enterprise is a sober guide to putting open source to work in the modern IT department. Open source software is software whose code is freely available to anyone who wants to change and redistribute it. New commercial support services, smaller licensing fees, increased collaboration, and a friendlier platform to sell products and services are just a few of the reasons open source is so attractive to IT departments. Some of the open source projects that are in current, widespread use in businesses large and small include Linux, FreeBSD, Apache, MySQL, PostgreSQL, JBOSS, and Perl. These have been used to such great effect by Google, Amazon, Yahoo!, and major commercial and financial firms, that a wave of publicity has resulted in recent years, bordering on hype. Large vendors such as IBM, Novell, and Hewlett Packard have made open source a lynchpin of their offerings. Open source has entered a new area where it is being used as a marketing device, a collaborative software development methodology, and a business model. This book provides something far more valuable than either the cheerleading or the fear-mongering one hears about open source. The authors are Dan Woods, former CTO of TheStreet.com and a consultant and author of several books about IT, and Gautam Guliani, Director of Software Architecture at Kaplan Test Prep & Admissions. Each has used open source software for some 15 years at IT departments large and small. They have collected the wisdom of a host of experts from IT departments, open source communities, and software companies. Open Source for the Enterprise provides a top to bottom view not only of the technology, but of the skills required to manage it and the organizational issues that must be addressed. Here are the sorts of questions answered in the book: Why is there a "productization gap" in most open source projects? How can the maturity of open source be evaluated? How can the ROI of open source be calculated? What skills are needed to use open source? What sorts of open source projects are appropriate for IT departments at the beginner, intermediate, advanced, and expert levels? What questions need to be answered by an open source strategy? What policies for governance can be instituted to control the adoption of open source? What new commercial services can help manage the risks of open source? Do differences in open source licenses matter? How will using open source transform an IT department? Praise for Open Source for the Enterprise:"Open Source has become a strategic business issue; decisions on how andwhere to choose to use Open Source now have a major impact on theoverall direction of IT abilities to support the business both withcapabilities and by controlling costs. This is a new game and onegenerally not covered in existing books on Open Source which continue toassume that the readers are 'deep dive' technologists, Open Source for the Enterprise provides everyone from business managers to technologistswith the balanced view that has been missing. Well worth the time toread, and also worth encouraging others in your enterprise to read as well." ----Andy Mulholland - Global CTO Capgemini "Open Source for the Enterprise is required reading for anyone workingwith or looking to adopt open source technologies in a corporateenvironment. Its practical, no-BS approach will make sure you're armedwith the information you need to deploy applications successfully (aswell as helping you know when to say "no"). If you're trying to sell opensource to management, this book will give you the ammunition you need.If you're a manager trying to drive down cost using open source, thisbook will tell you what questions to ask your staff. In short, it's aclear, concise explanation of how to successfully leverage open sourcewithout making the big mistakes that can get you fired." ----Kevin Bedell - founding editor of LinuxWorld Magazine

Freely available source code, with contributions from thousands of programmers around the world: this is the spirit of the software revolution known as Open Source. Open Source has grabbed the computer industry's attention. Netscape has opened the source code to Mozilla; IBM supports Apache; major database vendors haved ported their products to Linux. As enterprises realize the power of the open-source development model, Open Source is becoming a viable mainstream alternative to commercial software.Now in Open Sources, leaders of Open Source come together for the first time to discuss the new vision of the software industry they have created. The essays in this volume offer insight into how the Open Source movement works, why it succeeds, and where it is going.For programmers who have labored on open-source projects, Open Sources is the new gospel: a powerful vision from the movement's spiritual leaders. For businesses integrating open-source software into their enterprise, Open Sources reveals the mysteries of how open development builds better software, and how businesses can leverage freely available software for a competitive business advantage.The contributors here have been the leaders in the open-source arena: Brian Behlendorf (Apache) Kirk McKusick (Berkeley Unix) Tim O'Reilly (Publisher, O'Reilly & Associates) Bruce Perens (Debian Project, Open Source Initiative) Tom Paquin and Jim Hamerly (mozilla.org, Netscape) Eric Raymond (Open Source Initiative) Richard Stallman (GNU, Free Software Foundation, Emacs) Michael Tiemann (Cygnus Solutions) Linus Torvalds (Linux) Paul Vixie (Bind) Larry Wall (Perl) This book explains why the majority of the Internet's servers use open- source technologies for everything from the operating system to Web serving and email. Key technology products developed with open-source software have overtaken and surpassed the commercial efforts of billion dollar companies like Microsoft and IBM to dominate software markets. Learn the inside story of what led Netscape to decide to release its source code using the open-source mode. Learn how Cygnus Solutions builds the world's best compilers by sharing the source code. Learn why venture capitalists are eagerly watching Red Hat Software, a company that gives its key product -- Linux -- away.For the first time in print, this book presents the story of the open- source phenomenon told by the people who created this movement.Open Sources will bring you into the world of free software and show you the revolution.

This handbook of research is one of the few texts to combine Open Source Software (OSS) in public and private sector activities into a single reference source. It examines how the use of OSS affects practices in society, business, government, education, and law.

Open source software finds its connections with free software and is part of free and open source software over the extended term. Open-source software (OSS) is a form of computer software program that releases source code under a licensing legitimacy wherein the copyright holder allows users the privilege to analyze, modify and share the software to anyone and for any productive purpose. Open-source software may be created either freely and collaboratively. Open-source software is a case in point of open collaboration. The progress of open-source software will offer assorted perspectives beyond those of a single enterprise A 2008 study from the Standish Group reported that the implementation of open-source software models culminated in savings for customers of around $60 billion (£ 48 billion) annually. Initiatives of open source software are undertaken and managed by a network of voluntary programming associations and are commonly used in the gamut of both free and commercial outputs.
