What are Linux and Open Source?

What is Linux?ƒ UNIX-like operating systemƒ Developed by open source "community"ƒ Packaged and shipped by distributors such as Red Hat, SuSE, Turbolinux, ...ƒ UnitedLinux = open industry consortium providing a binary-compatible Linux distribution

What is Open Source?ƒ Community develops, debugs, maintainsƒ Generally high quality, high performance software

"Hello everybody... I'm doing a (free) operating system (just a hobby, won't be big and professional...)."

Linus Torvalds, creator of Linux, from the first Internet announcement on August 25, 1991. Even he initially underestimated its potential.

Experiences with the Open Source Software Community

Open source developers and traditional software developers have the same goalsƒ Quality, high-performance, serviceable software that solves real

customer problemsDevelopers trained on proprietary software can successfully become effective Open Source developers (hundreds of proof points)

Linux community is enthusiastic about making Linux a mission-critical Open Source and supporting the necessary enterprise featuresƒ Scalability, security, reliability, serviceability, performance,

availability, manageability, standards, ...IBM is an accepted peer and partner in the Linux development community

The Open Source community includes all of us

Fact: Porting to Linux is Easy

Porting tools and documentation available on developerWorks

"Migrating UNIX web servers to Linux is one of the easiest migration scenarios in the industry."

D.H Brown, "Migrating Mail and Web Servers to Linux", August 2002

"Several large projects of moving UNIX-based applications from 100 kloc to 600 kloc have been completed. Most were completed in about 2 months and only required a small percentage (1% or so) of the code to be modified in any way."

SoundView Technology Group, "Linux Momentumin Europe Appears to be Strong", June 2002
