Overview �Definitions �History and evolution of Linux �Current development �In reality ◦ United States �Business users �Individual users and manufacturers ◦ World Wide

What is Linux? �Linux is defined as a “Unix-like” operating system assembled under the model of free and open source software development and distribution.

…Open Source? �Open Source is a type of software liberally license to grant users the right to use, copy, study, change, and improve its design through the availability of its source code.

…Operating System?

From the Beginning �Unix ◦ Released from AT&T’s Bell Laboratories in 1971. ◦ Open source until 1984, which led to an initial growth of popularity.

Further Ahead �GNU Project ◦ 1983 through the early 1990’s. ◦ Richard Stallman. ◦ Goal: create a Unix compatible software system composed of entirely free software. ◦ The Free Software Foundation. ◦ GNU General Public License (GNU GPL). ◦ Wrote Unix like applications including libraries, compilers, text editors, Unix shell, and a windowing system. ◦ Where’s the kernel?

Even Further Ahead �Minix ◦ Andrew S. Tanenbaum. ◦ Fully completed Unix-like operating system. ◦ Catch: Designed and licensed for computer educational use only.

In the End �Linux ◦ Linus Torvalds ◦ Step 1 – Took Minix and wrote a kernel to replace the Minix kernel. ◦ Step 2 – Adopted GNU applications to work with the Linux kernel. ◦ Step 3 – Applied the GNU GPL to his product. ◦ Step 4 – Complete integration of GNU applications and Linux kernel to create the fully functional and free operating system.

Current Development � Embedded systems � Servers � Supercomputers � Desktops � Most popular Linux Distributions: ◦ Linux Mint ◦ Ubuntu ◦ Fedora ◦ Debian ◦ Open. SUSE � Torvalds remains working on the kernel. � Stallman leads the Free Software Foundation GNU applications. � Third party developers. and develops

Business Users � The Linux Foundation conducted a survey with 1, 900 people, 428 respondents of whom work for organizations with sales of more than $500 million or 500+ employees � Key points ◦ Continuing use of Linux ◦ Linux is able to handle “Big Data” ◦ Top reasons for businesses choosing Linux

Continuing use of Linux � Relative to other operating systems, in the next five years do you think the use of Linux in your company or organization will: Increase Stay the same Not sure Decrease 79. 8% 11. 3% 7. 5% 1. 4%

Big Data � In the next 12 months, what are your company’s plans to support Big Data? Adding more Linux Adding more Windows Adding more Unix Have no plans to add more servers 71. 8% 35. 9% 28. 7% 17. 6%

Top Reasons for Linux � What are your drivers for adopting Linux? Lower total cost of ownership (TCO) Features/technical superiority Security In-house talent experience with Linux No vendor lock-in Openness, ability to modify code Long-term viability of platform Choice of software Choice of hardware Other (please specify) 70. 0% 68. 6% 63. 6% 52. 7% 52. 5% 50. 8% 47. 5% 38. 5% 37. 1% 5. 0%

Single Users �Not that many ◦ Many people do not want the trouble. �Solutions ◦ Buy a laptop/desktop with Linux installed on it.
