What is Linux…? /ˈlɪnəks /LIN-əks

• Linux was started in 1991 by Linus Torvalds as a replacement

for the 386-based Minix system

• Linux is an operating system kernel developed as an open

source project

• Linux vendors build Linux into “distributions”—these are

compilations of free software built around the Linux kernel and

sold for a fee

4

Where is Linux?

5

Linux Kernel Development: How Fast it is Going, Who is Doing It, What They are Doing, and Who is Sponsoring It (2013 Edition) http://www.linuxfoundation.org/publications/linux-foundation/who-writes-linux-2013

Who develops Linux?

• The Linux Foundation

maintains upstream

commitments from the

OpenSource Community

• Hardware, Software and

Individual contributors

provide code for the

managed subsystems

• SUSE and IBM are

traditionally top 10

contributors

6

Why Use Linux?

Power of the Community

Freedom of Choice

Top Service Levels

Best of Breed Technology

Result: Linux is the fastest growing operating system

7

Is Linux Free? Yes and No

Yes No

Linux is licensed under the GNU General Public License (GPL) and is free. You can freely:

● Distribute it

● Modify it

● Use it

But there is a cost associated with using Linux:

● Cost to integrate, deploy and secure

● Cost to certify, support and maintain

● Opportunity cost

8

Benefits of a Paid Subscription

• Timely, tested and guaranteed security updates

• Prompt resolution of support issues

• Patches that preserve application compatibility

• Hardware and software certifications

• Technology Assurance Program indemnification

Result: Allows your staff to focus on more valuable strategic initiatives

Points to consider

Addressing Today’s Challenges

How do I keep up with

technology innovations

UNIX does not support?

– Virtualization

– Cloud Computing

– Server Consolidation

– Big Data

– Analytics

– Mobility

Is my OS/Hardware aligned to

my strategic business needs?

– Reduce licensing costs

– System Interoperability

– Are my mission critical

applications optimized to

enhance the performance of the

workload?

– Does my OS take full advantage

of my hardware?
