The document discusses the principles, advantages, and disadvantages of open source software, along with examples and case studies of its use in enterprise settings. It highlights the growing adoption of open source technologies like Linux, Apache, and MySQL, and addresses common objections and misconceptions about their security and support. The piece also evaluates the cost/benefit analysis of open source versus proprietary software, suggesting that while open source can be cost-effective, it often comes with its own set of challenges and learning curves.

3. Principals of Open Source Free redistribution Source code must be included Must allow modifications and derived works Integrity of the author's source code No discrimination against persons or groups No discrimination against fields of endeavor A single license must apply to all users License must be technology-neutral

4. Examples of Open Source Software Apache — the most popular Web Server Firefox — fast growing Web Browser Linux — growing in data center and even desktop phpBB — a forum system FreeBSD — a version of UNIX ® Java — a programming language Partially Open Source Free, as in free beer

5. Examples of Open Source Software Tomcat — Java servlet environment OpenOffice — alternative to MS Office JBoss — Java app server MySQL — lightweight database Python, Perl, PHP — scripting languages Eclipse — platform-independent, application development framework

6. Apache is King

7. Firefox a Contender

9. Sun and Open Source Sun has opened many of their apps and plaforms: Solaris Operating System NetBeans Project Looking Glass Project JXTA Jini OpenOffice OpenSPARC Java EE

10. Open Source: You’re Soaking In It Answer the following questions to see if your organization is using open source software: Does your team use Firefox, Linux, Apache Web server, or MySQL? Do you use gcc or g++ for compiling? Does your team build executables using make? How about the Bash shell, grep, gzip, sed, calc, ed, Emacs, Finger, or uucp? Do you use CVS or Bugzilla? How about WebSphere?

11. Enterprises Run Open Source Google runs on Linux Linux runs PlayStation 2 and 3, several arcade games, and embedded devices such as mobile phones, routers, and stage lighting systems Packaged software running Linux is expected to exceed $357 billion by 2008 IDC says that Linux holds 12.7% of the overall server market Q1 2007

12. Enterprises Run Open Source JBoss has #1 market share (34% penetration according to BZ Research) and used by >400,000 developers

13. Enterprises Run Open Source MySQL – With more than 50,000 downloads per day MySQL has 40% database usage by developers

16. Disadvantages of Open Source No guarantee of progress — project may never reach a usable stage, and may die later if there is not enough interest Possible problems with intellectual property — difficult to know if some particular method is patented Sometimes difficult to find a project and its current status — not much advertising for open source software

17. Disadvantages of Open Source Restricted choice — commercial software may offer dozens or hundreds of choices Poor integration with Microsoft — Open Source products tend to be created by people who do not want to work with Microsoft Poor vertical integration — software tools rather than solutions Poor user interface/Difficult to use — Open Source products are written by power users

18. Disadvantages of Open Source Higher cost of installation — a greater degree of expertise usually is required for installation Lack of capabilities / features — Open Software packages may have far fewer features and capabilities No warranty — you are on your own There is no single company backing the product

19. Common Objections Open source isn’t really free — Implementation, administration, and support costs There’s no service and support — For some companies, support is mandatory Development resources can be scarce — Linux and open source resources may not be abundant in your area or industry. However, with the evolution of Mono (the open source equivalent to NET), Windows NET developers become an added development resource for Linux

20. Common Objections Open source may not be perceived as secure — If the code is available, anyone can figure out how to break it Training may not be available — Training lags MS alternatives, but Novell has created multiple levels of Linux certification and integrated training programs All open source is a work-in-progress — True for some, but not for all The key components like Linux, Apache, MySQL, and Tomcat are dominating prime-time Internet with stable, secure, and production-quality solutions

21. How We Use Open Source The WiMAX Guys’ business: Wi-Fi installations in hotels IT consulting for small hospitality companies Web hosting Email hosting

22. How We Use Open Source Wi-Fi installations in hotels: Kismet – 802.11 layer2 wireless network detector, sniffer, and intrusion detection system – good for identifying other WLANs in the area AirSnort – recovers WEP encryption keys – used if existing WLAN operator has lost access – friends don’t let friends use WEP! Operating against a saturated 802.11b network AirSnort took 273659 unique packets and 8 minutes to crack a 128 bit WEP key

23. How We Use Open Source Wi-Fi installations in hotels: NetStumbler – wireless network detector, sniffer: Verifying network configurations Finding locations with poor coverage Detecting causes of wireless interference Detecting unauthorized (“rogue”) access points Aiming directional antennas for long-haul WLAN links

31. Downside of Open Source You have to learn to love the command line interface! Linux needs better installation methods and utilities No Spider solitaire

32. Should You Use Open Source? Is the software well established or still in its infancy? Are there regular updates, patches and new features? Is there a support forum? Are the support forums active? Do forum participants help each other out? Are reputable companies using the software? Is the documentation complete and coherent? What are the general costs with hiring contractors who are familiar with the software?

33. Just Don’t Expect it to be Free “ And did we mention that it's free? Okay, not exactly. Backcountry[.com] has estimated that with all its up-front costs and consulting fees, its open-source shop cost $380,000. That includes operating system, databases, e-commerce platform, knowledge management, and e-mail. The company figures the same setup from traditional software vendors would have run up to $3 million.” Source: “Own the Code”, Inc.com, 1/07

34. Just Don’t Expect it to be Cheap[er] Costs of Acquisition and Support – A Comparison – August 2005 – PREPARED FOR Microsoft 1 Microsoft’s Windows Server 2003 enterprise license and support costs are competitive with Red Hat Enterprise Linux 2 The two companies’ different approaches to enterprise licensing and support, and the fact that investments of this magnitude tend to involve longer-term commitments, means that the best pricing comparisons should be based on a period of ownership (three to six years), rather than on just initial acquisition charges 3 Support is integral to both companies’ solutions and Microsoft’s separate support and license fee structures, in contrast with Red Hat's combined subscription and support offerings, can give a Microsoft solution a significant pricing advantage over a Red Hat solution Source: http://wwwmicrosoftcom/windowsserver/compare/ReportsDetailsmspx?recid=5
