Linux Basics
 Written by Linus Torvalds at the age of 21
 Linux first available on the web in 1991
 It is open source (you can view the programming instructions)
 www.kernel.org is the Linux archive
 Maintained / developed by individual programmers around the world
 Two largest vendors are RedHat and Novell
Linux Basics
Proprietary versus Open Source
Proprietary development is the most widely used model across the software industry
someone basically says, "I created this, I paid for the people who developed it, so it's mine
and I'll do with it what I choose."
Value proposition: Sell Licenses
open-source development means some or all of a product's source code is
available, as well as the executable code, so everyone can access, alter and distribute it.
Value proposition: Common OS platform that can work across
different hardware types, can mean lower development costs and
higher quality code
Linux Basics
Red Hat and Novell are the two largest Linux vendors. They add value by:
Certified solutions
Testing with major vendors
Maintenance
Errata's available quarterly
Hot fixes / PTFs available
Support
Diagnostic help available

Linux at IBM
"IBM was very interested in Linux because of its interoperability
across its different platforms and devices"
IBM owns many operating systems:
MVS – Mainframe
OS2 – Desk Top (EOL)
VM – Mainframe
VSE – Mainframe
AIX – RISC
IBM's goal is to build a portfolio so that customers have flexibility, scalability,
and interoperability with our investment in open source development
Linux at IBM
The Linux Technology Center (LTC) is IBM’s open source
development team. Our mission is:
 Help make Linux better
 Assist the IBM Hardware, Software, and Services brands win
with Linux
 Expand the reach of Linux
 Remain trusted, valued members of the Linux community
Linux at IBM
LTC has about 900 people working in 38
locations.
Primary US locations:
Beaverton, OR.
Rochester, MN.
Endicott, NY.
Poughkeepsie, NY
Raleigh, NC

Linux at IBM
Critical Customer Situations
Definition: When normal processes have failed and IBM
customer satisfaction is at risk the sales team will utilize a
process called Customer Satisfaction Management and
specifically Critical Situation Management (Critsit)
The goal is to have IBM customers walk away from a situation
satisfied with the resolution and ensure that they stay an IBM
customer
TPM’s are held personally accountable for these situations and
their resolution. IBM follows these situations closely with
executives and if customers go away unhappy the TPM must
explain “why” as part of the overall quality process.
Linux Important Points
You can use both proprietary and open source solutions in the IT environment,
it just depends on what your business needs are
Always purchase support! Most companies will tell you that they thought they
had a lot of knowledge on Linux but knowledge did not translate to experience
in the enterprise environment.
Always consider the Total Cost of Ownership for any solution. A solution that
looks simple may be very complex when fully assembled.
