2 © Gulf Computers L.L.C. www.gulfcomputers.com 2 Table of Contents  What is Open Source Software (OSS)  What is Linux?  Who is using OSS for business today?  Why consider Linux for your company's computer?  Selecting server platforms: case study  Gulf Computers solution

3 © Gulf Computers L.L.C. www.gulfcomputers.com 3 What is Open Source 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 © Gulf Computers L.L.C. www.gulfcomputers.com 4 What is Open Source 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 © Gulf Computers L.L.C. www.gulfcomputers.com 5 What is Open Source 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

6 © Gulf Computers L.L.C. www.gulfcomputers.com 6 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

7 © Gulf Computers L.L.C. www.gulfcomputers.com 7 What is Linux?  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.

8 © Gulf Computers L.L.C. www.gulfcomputers.com 8 What is Linux?  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

9 © Gulf Computers L.L.C. www.gulfcomputers.com 9 What is Linux?  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 © Gulf Computers L.L.C. www.gulfcomputers.com 10 What is Linux?  So what’s is the bad news?  Modems  Scanners  Can Linux run Windows software?  How much does it cost ;-) ?

11 © Gulf Computers L.L.C. www.gulfcomputers.com 11 Who is using OSS for business today?  Web servers (as of June 2003, 40 million web sites worldwide. Source: www.netcraft.com) Webserver%Change % Apache66.52+1.31 Microsoft IIS24.64-0.90 SunONE1.18-0.03

12 © Gulf Computers L.L.C. www.gulfcomputers.com 12 Who is using Linux for 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

13 © Gulf Computers L.L.C. www.gulfcomputers.com 13 Who is using Linux for business today?

14 © Gulf Computers L.L.C. www.gulfcomputers.com 14 Who is using Linux for business today?

15 © Gulf Computers L.L.C. www.gulfcomputers.com 15 Who is using OSS for 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 © Gulf Computers L.L.C. www.gulfcomputers.com 16 Who is using Linux for business today?  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 © Gulf Computers L.L.C. www.gulfcomputers.com 17 Who is using Linux for business today?  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 © Gulf Computers L.L.C. www.gulfcomputers.com 18 Who is using Linux for business today? 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 © Gulf Computers L.L.C. www.gulfcomputers.com 19 Why consider Linux for your 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 © Gulf Computers L.L.C. www.gulfcomputers.com 20 Why consider Linux for your company'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 © Gulf Computers L.L.C. www.gulfcomputers.com 21 Why consider Linux for your company's computer 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 © Gulf Computers L.L.C. www.gulfcomputers.com 22 Why consider Linux for your company's computer 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 © Gulf Computers L.L.C. www.gulfcomputers.com 23 Why consider Linux for your company's computer 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 © Gulf Computers L.L.C. www.gulfcomputers.com 24 Why consider Linux for your company's computer 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 © Gulf Computers L.L.C. www.gulfcomputers.com 25 Concerns 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

26 © Gulf Computers L.L.C. www.gulfcomputers.com 26 Case Study: How spending less than 200$ saved one company over 20,000$?  ABC Inc. $50 million/year company (NJ)  10 offices around the U.S., 75 employees  Migrate from Novel 3.1 to Novel 4.0, or Linux or Windows NT/2000 to offer web services  Server is transparent to the end-user
