What is Open Source What is Open Source Software (OSS)Software (OSS)

Source code is available (under a particular license)

Emacs, Apache, Sendmail, Bind, Linux…

OS Cost Model compared to Traditional Commercial Off-The-Shelf (COTS)


4

What is Open Source What is Open Source Software (OSS)…Software (OSS)…

Benefits of OSS Compared to Traditional COTS Extensive technical expertise High level of software efficiency Rapid release rate of OSS Code re-use reduces development time Indefinite lifetime of OSS Based on open standards and high degree of

interoperability.


5

What is Open Source What is Open Source Software (OSS)…Software (OSS)…

What is today’s user choice? Windows/Mac: choice of applications and

ease of use Unix: performance, availability, quality,

security, brand/reputation, support. Linux: low price and reliability

What is Linux?What is Linux?

Linus Torvalds in 1991(University of Helsinki, Finland)

Version 1.0 in 1994 Official mascot: the Linux Penguin 18 million users worldwide as of June

2003

What does it do? What does it run on?

Intel’s, Motorola (Mac), Sparc (Sun), Risc (IBM), MIPS (SGI), even IBM 3/90, Xbox and PDAs

How big it is? Linux: 1.5 million lines of code. Windows 2000: over 38 million loc.

What desktop environment? KDE, GNOME (User choice) Customizable (skin download):

Windows, MacOS, BeOS look and feel

What applications?Everything!:Server apps, Desktop apps, games…

What it is used for today?Web servers, file and printing servers

What is good for? Mission critical apps Clustering (Linux Supercomputer)

Who is maintaining it? Kernel maintained by Linus Torvalds GUI not singularly maintained

How many distributions? Over 200! Red Hat, SuSE, Caldera, Debian, Mandrake, …


10


So what’s is the bad news? Modems Scanners

Can Linux run Windows software? How much does it cost ;-) ?


11

Who is using OSS for Who is using OSS for business today?business today?

Web servers (as of June 2003, 40 million web sites worldwide. Source: www.netcraft.com)

Webserver % Change %

Apache 66.52 +1.31

Microsoft IIS 24.64 -0.90

SunONE 1.18 -0.03


12

Who is using Linux for Who is using Linux for business today?business today?

(These results were obtained from an InformationWeek survey of 300 IT managers in May 2002):

About 26 percent of companies currently use Linux

80% companies that run Linux use it to serve Web pages

Nearly 60% use it for application development just 11% use it in supercomputer clusters

Who is using OSS for Who is using OSS for business today?business today?

U.S.: NASA, Google, ISPs, Web servers,

France: e-Government, ISPs, France Telecom, Web servers

Germany: Federal Government, ISP, Web servers

Spain, Korea, Brazil, etc…


16


Satisfaction with Linux: 99% of companies running it report some level of

satisfaction 84% say they're extremely satisfied

Usage is growing 85% of managers running Linux will buy more Linux 44% of managers running Windows will buy more

Windows 13 % of managers running Unix will buy more Unix


17


OS business model will result in a 20% savings in the IT server budget (GartnerGroup )

The total cost of running Linux is about the same as NT, Unix, or anything else (Computerworld)


18


Open vs Closed source decision is based on three factors:

1. Costs

2. Benefits (e.g. performance);

3. More intangible criteria (e.g., quality of peer support).


19

Why consider Linux for your Why consider Linux for your company's computer?company's computer?

Windows (--) Cost (Rental Model, shelfware) Slow bug fixing/support Security/vulnerability Lack in the Remote Admin

Linux (++) Cost (you pay only for what you need) Security Stability Reliability Licensing


20

Why consider Linux for your Why consider Linux for your company's computercompany's computer

Benefits- Dramatic Cost Reduction GNU General Public License (GPL) or similar Linux: free for download, or set of CD's ($10 to $180) Free license of office suite, Free license DB, Free license of server software (file/printer sharing, web

servers, etc), Reasonably priced commercial software, Free license of software development environments

(including language compilers)


21


Benefits- Security Linux is a very secure OS. Comes with firewall software Programmers around the world are trying to

find holes When one is found it is fixed immediately Linux has avoided almost all major viruses,

worms, and Trojan horses (Nimda, Code Red,…)


22


Benefits- Stability Linux community is committed to it's stability Linux is built with the Unix philosophy:

keep modules small and simple make sure it is stable every step of the way

Linux is separate from what runs on top of it Windowing system is not part of Linux Tired of rebooting (ctrl-alt-delete)

Even if you pull the plug on your computer, your files are safe


23


Benefits- Reliability Fewer Crashes = Longer Uptimes = Less

Labor ZDNet 10 month well formed study NT

crashes - 7 times, Linux - 0 Bloor Research, 1 yr, well formed study NT

crashed 68 times, Linux 1 time


24


Benefits-Business Friendly Licensing GNU General Public License (GPL) or similar

licenses (BSD) No software police Commercial packages under Linux done by

small companies, and deserve your support.


25

Concerns and ResponsesConcerns and Responses

Many businesses still don't entrust their toughest computing tasks to OSS: Open source isn't high enough in quality: False Open source isn't supported: False Open source is too risky as a technology basis:

False Open source licensing is too restrictive: False
