Transcript of Linux Presentation
A Free and Open Source OS what is Linux?
One of the most successful free open source software that is a UNIX clone
It was created by programmer Linus Torvalds
The largest part of the work on Linux is performed by the community that is the thousands of programmers around the world "Microsoft isn't evil, they just make really crappy operating systems" hISTORY:
1960-80's : context of the creation of Linux
Existing operating systems: UNIX, GNU Project, BSD and MINIX
1991: Linus Torvalds created Linux kernel as a student at the University of Helsinki
the Linux kernel is licensed under the GNU GPL
the first Linux distributions are created
1993: Over 100 developers work on the Linux kernel
1997 : Titanic was produced on Linux servers
1998: Many major companies such as IBM, Compaq and Oracle announced their support for Linux and others began distributing it Distributions Linux Today Linux Users Programmers: It has tons of pre-installed or compatible tools and utilities. Linux is a programmer's heaven.
Business Owners: A lot of business owners are using Linux for its free and open source finance and accounting software. This is an example of B2B, B2C usage.
Artists: This includes professional graphic designers, photographers and animators. Thie first major film produced on Linux servers was 1997's Titanic. Linux servers were also chosen for Avatar.
Geeks: C2C usage includes the Linux basic user community. On the Linux website, members can creat profiles and network. Revenue model Assumption: "You do not make money out of open source"
Almost all Linux distributions are available for free download
A significant time and cost invovled
Linux can generate revenue while still being free
A revenue model based on the principle of copyleft
Technical support mixed with services: the success model of today
Hardware and cash donations, employment of programmers
IBM, HP, Red Hat.. make money by selling products and services around the Linux OS as well as individuals working as Linux server administrators, or customizing Linux installations Red Hat Linux Case not to be confused : Linux kernel : an operating system (OS) kernel
Linux : a family of Unix-like OS using Linux kernel
Unix : an OP developed in 1969 at AT&T Bell Labs
Linux distribution : a software distribution based on Linux kernel The lack of a widely-adopted and free kernel provided the impetus for Torvalds's starting his project
A non-traditional corporation : no headquaters, no CEO and no annual report
A cooperative venture : two dozen companies and thousands of individuals working together
A meritocratic culture : people with the most to offer win recognition and prominent roles
A $49 billion business by 2011 according to the IDC Analyst group
IDC projects that Linux support sales will top $1 billion in 2012
The strongest rival Microsoft that has ever faced
In 2009, Linux had 33.8% revenue marketshare of servers compare to Microsoft's 7.3%
→ Can be installed on a wide variety of computer hardware
(mobile phones, tablets, computers and video game consoles and supercomputers)
→→ Runs 446 of the world's top 500 supercomputers
Movie director James Cameron chose Linux servers for Avatar
Google runs its web servers on Linux The corporation The software The business Over 300 distributions are deployed today
Debian was the first truly community-oriented distribution Debian's source code (283 million lines) would have cost $7.37 billion to produce in a commercial environment Provides the distributions on CDs rather than online
Support for installation
Online + onsite assistance to answer technical questions
Training employees to use the product
Upgrades services : long-term agreements to get the latest upgrade Commercial distributors of Linux-based systems might have faced quite a challenge in finding a successful revenue model for setting up such businesses Crowd Wisdom
All the underlying source code can be used, freely modified, and redistributed, both commercially and non-commercially, by anyone! Improvements and developements are constantly being made through tools such as:
Linux Foundation- Helps to promote, protect and advance the Linux platform.
Forums Quick Facts: $7.37 billion would be the projected
cost to produce that amount of code
in a commercial environment. federal government of
Brazil favors Linux
operating sytems over
all others in its PCs. IBM chose Linux for its supercomputer,
Sequoia, due out this year.
It is supposed to have the processing
power of two million laptops.
