Presentation Overview
  • What is Free Open Source Software (FOSS)?
  • History, philosophy, how it works
  • Pros cons
  • Examples
  • The Business Case for FOSS
  • ROI calculations
  • Usage trends

Brief History
  • Free Software
  • 1983 Richard Stallman launches GNU project
  • To create a sufficient body of software to
    get along without any software that is not free
    1
  • 1985 Stallman starts Free Software Foundation
    (FSF)
  • Open Source Software
  • 1998 Netscape releases its source code under
    Netscape Public License
  • In response to Microsoft making Internet Explorer
    free
  • 1998 Bruce Perens and Eric S. Raymonds start
    Open Source Initiative (OSI)

How Does It Work?
  • Developer gets an idea, scratches that itch
  • Hello everybody out there using minix - I'm
    doing a (free) operating system (just a hobby,
    won't be big and professional like gnu) for
    386(486) AT clones. Linus Trovalds, creator
    of Linux in 1991 1
  • Uploads code to a place where others can access
    it
  • For example, SourceForge or FreshMeat
  • The code is published under an open source
    license
  • Such as GPL, the GNU Public License

How Does It Work?
  • Informal process of software development
    commences
  • Ideas shared, trial and error, software improves
  • Software changes direction
  • Software gets finished or is forgotten
  • Linux, Apache, Firefox maintained by thousands
  • Others maintained (if that) by one or two people
  • Developers come and go, project becomes active or
    dormant
  • Unless someone takes responsibility for
    maintaining it (e.g. Red Hat, Apache Foundation,
    Mozilla.org, etc.)

6
Open Source Philosophy
  • Users should be treated as co-developers
  • Linus Law Given enough eyeballs, all bugs are
    shallow
  • Release early versions quickly
  • Have frequent integrations into the rest of the
    code
  • Have several versions of the software
  • Stable and buggier versions
  • Have high modularity
  • Have a dynamic decision-making structure

The Good, The Bad
  • Pros
  • License is free
  • No vendor lock-in
  • Large developer base
  • Community support
  • More reliable
  • More secure
  • More flexible
  • More localization (i.e. more multi-lingual)
  • Cons
  • Many versions, vendors
  • Fear or no one to blame
  • Fewer features
  • Limited desktop use (for now)
  • Limited marketing
  • May have limited interoperability
  • Documentation quality varies

The Ugly
  • Myths
  • Attraction is price tag
  • Savings arent real
  • Theres no support
  • Its a legal minefield
  • Its insane for mission-critical applications
  • Funny, since over 50 of FOSS use is in this area
  • It isnt ready for the desktop
  • 26 of surveyed companies are using it on the
    desktop

Trends
  • FOSS is moving up the software stack (i.e. from
    the server level to the desktop)
  • From Linux MySQL to Firefox OpenOffice.org
  • Is used frequently within business departments
    but not across the enterprise
  • There is an increased interest is FOSS at all
    levels of the organization

Some Numbers
  • FOSS saved companies money in 2004
  • Large companies (1b revenues) 3.3m
  • Mid-sized companies (50m to 1b) 1.1m
  • Small companies (
  • 33 of 600 companies surveyed in 2006 used open
    source databases
  • 50 of web servers on the Internet in October,
    2007 use Apache

Cost Impact
23
Benefit By Industry
24
Biggest Barriers
  • Executives lack knowledge about benefits, have
    quality and support fears
  • Legal and licensing issues
  • Corporate cost allocation policies dont
    incentivize reduction in cost of commercial
    software
  • Difficulty of procuring open source systems that
    will be supported after installation

Bottom Line
  • Its not a technology issue, its a business
    issue
  • Key is to identify which projects make sense for
    open source and which dont
  • Do the usual ROI calculation and make your choice
    accordingly
