I was always fascinated with Free and Open Source Software, FOSS. So I decided why not present it for an academic seminar?
Here's the full PPT...

  4. 4. CONTENTS contd.. ● FOSS SOFTWARE DEVELOPMENT MODEL ● WHICH LICENSE TO USE? ● SHORTCOMINGS OF FOSS ● HOW TO START OR CONTRIBUTE TO FOSS PROJECT ● FUTURE PROSPECTS
  5. 5. INTRODUCTION ● A very promising and profitable industry. ● FORBES - 65 software companies in the 2010 edition amongst top 2000 large companies active in all kinds of industries. ● DataMonitor forecasts that in 2013, have a value of US$ 457 billion ● Bill Gates, the founder of Microsoft was the richest person by selling software products. ● The success story of Oracle . The same happened with Larry Ellison
  6. 6. ● Conventional software mostly are proprietary ● Sealed inner mechanism ● Free and Open Source Software made with just the opposite mindset ● The tremendous contributions to computing, both research and commercial projects ● making easier for large group of people. ● growing phase, promising future ● In this seminar I have tried to simplify the notion of FOSS, commercial and non-commercial projects.
  7. 7. WHAT IS FOSS? ● There are two terms to separate in FOSS. ● “Free software” is a matter of liberty, not price. ● Freedom to − Run (freedom 1) − Study how program works (freedom 2) − Redistribute copies (freedom 3) − Modify / improvise (freedom 4) ● “Open” mainly points to Open Source Code of the program, available for others. ● get software at no cost but as per license we can enjoy the above four
  8. 8. ● going through phase of immense transformation. ● Currently it is worth $60 billion ● SourceForge.net hosts more than one million users, involved in some way with approximately one hundred thousand projects ● no real geographic barriers ● These figures speak volumes, something unique about the philosophy of FOSS ● Freedom, grow beyond its creators POPULARITY OF FOSS
  9. 9. Popularity of Apache Web Server
  10. 10. Cost comparison between Microsoft and FOSS Solutions Microsoft Solution Linux/FOSS Solution Savings Company A: 50 Users $87,988 $80 $87,908 Company B: 100 Users $136,734 $80 $136,654 Company C: 250 Users $282,974 $80 $282,894 Sources: wikibooks.org

  15. 15. HOW TO MAKE MONEY FROM FOSS ● 1)Dual license model ● released under a restrictive open-source license ,provide an alternative proprietary license. ● You have some sort of monopoly in the market leader ● Motivation: Client likes product and needs it for commercial use. does not want to breach the open-source license and is willing to pay ● Open-source license: GPL suitable license to this strategy because it is restrictive ● Examples: ● Mozilla Foundation has a deal-partnership with Google and other companies ● Apple Inc. offers Darwin for free, selling Mac OS X. ● Red Hat offers the Fedora for free, selling Red Hat Enterprise Linux (RHEL). ● MySQL is offered for free, but with the enterprise version you can get subscription, support and additional features.
  16. 16. 2)Dual product model ● penetrate the market by releasing an open-source product, ● sell a different product with an extended version, plug-ins or up- gradation. ● Motivation: The user gets to be a part of an open-source community process, contributes to the source and improves it. Users purchase other related products from the project professionals. ● Open-source license: MIT, BSD, Apache or any other non- copyleft license. ● Example: ● Eclipse and its non open source plug-ins. ● Sun Microsystems offer OpenOffice.org for free, while selling StarOffice.
  17. 17. 3)Professional services model ● This strategy requires a large base of clients ● the product must not be simple to use ● There is no problem implementing this strategy combined with one of the other strategies discussed before ● In fact it is recommended as a complementary strategy for both. ● Motivation: We are the experts in this open-source project because we wrote it, therefore clients would like to purchase support and other services from us. ● Open-source license: Any ● Example: ● a) JBoss itself is open source but RedHat provides a support subscription for JBoss Enterprise Middleware with prices from around $6000 to $110,000 per year
  18. 18. 4) Open source bounty ● It is a reward, usually monetary, for making positive contributions to an open-source project. ● Eg.BountySource ● Motivation: there is at least someone in this world who can solve my problem. ● Examples: ● Sun MicroSystems has offered $1 million in bounties for OpenSolaris, NetBeans, OpenSPARC, Project GlassFish, OpenOffice, and OpenJDK. ● The Google Summer of Code and the OSU Winter of Code provide stipends to students working on open source code. ● Mozilla introduced a Security Bug Bounty Program offering $500 to anyone who finds a "critical" security bug in Mozilla. ● Bounties are often used for implementing minor features, whereas bidding and/or grants are more typically used for major features.
  19. 19. RUNNING A PROFITABLE BUSINESS WITH FOSS ● Initial research for feasibility criteria. ● tool for strategic planning and decision support since running a profitable business is not easy. ● Two methods for software models ● total cost of ownership (TCO) ● the return on investment (ROI)
  20. 20. TCO ● Direct Costs –those identified in traditional IT budgets, including (Hardware & software acquisition, operation and administration costs, etc) ● Indirect Costs – those costs generated from IT users including (Downtime due to misuse or mistakes, end- user operations, continuous training needs etc.) “TCO for free and open source projects can never be Rs.0 “
  21. 21. ROI ● We need a method to measure something more important. How much we will get in return on making an investment. ● A simple way to look at ROI ROI=RETURN/INVESTMENT
  22. 22. FOSS SOFTWARE DEVELOPMENT MODEL STONE SOUP MODEL
  23. 23. LICENSES
  24. 24. SHORTCOMINGS OF FOSS Lack of business applications ● Alhough GnuCash, TurboCash do exists, basic, polished accounting applications as good as Tally do not have FOSS equivalents at this time. ● Scarcity of competent people. It is rare for a software developer to encounter, say, accounting problems. ● Interoperability with proprietary systems ● not entirely compatible with proprietary systems. ● For organizations that have already paid massive amounts of capital into proprietary applications, may prove to be prohibitive Documentation and “polish” ● Established FOSS lacks the user-friendliness
  25. 25. ● No warranties- regarding virus and performance related issues. ● Staff must be open source savvy-When compared with existing proprietary systems. The cost of training is considered as a major disadvantage when migrating
  26. 26. HOW TO START OR CONTRIBUTE TO FOSS PROJECT ● Numerous websites hosting projects Contributing Time/Skills ● Most open source software is built completely by volunteers (without compensation) because they want a product that fits their needs. ● The list of skills of contributors may seem large, but every person has different skills to offer and your skills may be what it takes for a project to evolve. In most cases you do not need to be a programmer to help By adding his hands, eyes and associated skills to their project he may take project to the next level Product Purchases ● As with the Membership and Subscriptions, by purchasing goods from the project's store Donations ● Feel free to visit the project's home page to see if a donation link
  27. 27. The laymen Contributions ● as a user can give back in a way that requires no money and limited time. ● by filling bug reports and recommendation so they can fix issues and adapt the product to better fit the needs of the current users. ● ● As you have seen from the list there are many ways to help the community more in the long term.
  28. 28. FUTURE OF FOSS ● Currently, proprietary software is king. ● When you buy a new computer, you will be getting Windows That is the "default choice". ● However, it is not the only choice! Equivalents available ● There's plenty of money in open source for commercial vendors. Worth billions in IT world ● but there's also plenty of opportunity for customers to build and support their own open source derived projects. ● Free from VENDOR LOCK-IN forever ! ● We're in the 21st Century now. customers get to decide ● “The Customer Century.”
