Abstract
Linux is key to driving innovative new technology as well as
business models.
It's shaking up the established view of which operating systems
should be used for what workloads, while slipping quietly undersome very cool new applications.
In this talk, I'll focus on three areas of great opportunity as well as
challenge for Linux: the accelerating market for cloud computing,
Linux as a significant operating system for mainframes, and the
hope for Linux on the desktop.

Who is the user for cloud computing?
Could be ...
A user of a virtualized desktop on a thin or fat client.
A non-technical end user who accesses services through a browser or
via applications such as disk backup to remote storage. A cloud choreographer who strings together cloud-based services to
implement business processes.
A service provider who needs to handle peak load demands.
A developer who employs dynamic resource allocation in clouds to
speed application or solution creation.
An IT system administrator who does not build clouds but deploys onto
them, probably in addition to traditional managed systems.

What does a cloud computing user want?
Cloud-friendly applications
Resources: storage, processor, platform
APIs: the more standard the better
Interoperability among clouds (may learn of this need later)
Reduced capital expense
A good, workable pricing scheme
Quality of service, including
Availability
Reliability
Performance
Security
Privacy
I don't think any one of thesecontradicts the use of Linux, andthey all potentially encourage it.

Why people are using Linux on mainframes
Virtualization was introduced commercially on IBM
mainframes in 1972.
Hypervisor is integrated with the hardware
Sharing of CPU, memory and I/O resources Virtual network and virtual I/O
Reduced Total Cost of Ownership (TCO)
Environmental savings single footprint vs. hundreds of
servers
Consolidation savings less storage, fewer servers, fewersoftware licenses, less server management/support
Mainframe capabilities complement and enhance those
of Linux.

Why people are using Linux on mainframes
Utilization often exceeds 90%
Manageability of centralized Linux systems
Typical deployment needs:
High performance transaction processing I/O intensive workloads
Large database serving
High resiliency and security
Unpredictable and highly variable workload spikes
Low utilization infrastructure applications
Rapid provisioning and re-provisioning
Mainframe characteristics complement cloud user requirements

Possible futures for the Linux desktop
It goes away.
We stop using desktops, so who cares?
The Linux desktop becomes a tactic instead of a strategy.
One Linux desktop distribution ends up with 90% marketshare
among those using Linux desktops.
One Linux desktop distribution ends up with 90% marketshare
among alldesktops.
We reach 33% / 33% / 33% parity with Microsoft Windows /

Possible futures for the Linux desktop
We stop pretending that it will be a drop-in replacement for the
dominant desktop operating system, and make it something better.
The enterprise sweet spot for Linux desktops is virtualizedLinux
desktops.
We focus on usability, stability, security, reliability, performance, with
some cool thrown in.
It's the browser, stupid.

2008 Prediction 1Green will drive significant initiatives in open source
This is happening as major customers such as banks move to
reduce their carbon footprints by consolidating onto mainframes,
often getting features such as disaster recovery as a bonus.
Aside from tangential benefits of using Linux, I'm not seeing much
yet in the way of open source being applied to green initiatives ina focused and specific way.
Linux will help reduce energy consumption through serverconsolidation, virtualization, load balancing and more efficient
resources management.

2008 Prediction 2Linux will not be replaced
I doubt anyone can seriously argue that any other open source
operating system has made significant inroads on the growing
installed base of Linux in the last year.
Linux will be introduced to thousands more users via implementationsin mobile phones, though users may not know it.
Much of the hot technological action is happening on Linux, such as
virtualization, and this will be essential for cloud computing.
Linux will increasingly find itself competing against proprietaryvirtualization technologies.

2008 Prediction 3Linux mindshare will be less x86 focused
In the cloud, users may not know there is Linux Inside, much
less x86 Inside.
From a device perspective, users will think less of operating
systems and chips, but more of user interfaces, media,connectivity, applications, app stores, and coolness.
Customers are more than capable of choosing the correct
hardware platform to match their planned workloads.
The instability and uncertainty in the industry this year is
causing customers to re-evaluate their software/hardwareplatforms and has been a great opportunity for Linux and
competitive winbacks.

2008 Prediction 7Open standards will grab more attention
The Open Document Format (ODF) is being approved for use in
more and more countries around the world.
Recent adoptees include Malaysia, Norway, Ecuador, Venezuela,
Taiwan, Hungary, and Latvia. The Open Cloud Manifesto has over 250 companies and groups
supporting it.
The industry and users will benefit the most from an emerging
technology when open standards are at the core, and there as earlyas possible.

Finishing up ...
Linux is at the center of the computing we have today and that which
we are building for tomorrow.
I believe the Linux community and
leadership will rise to tackleany challenges necessary to
meet and exceed
expectations.
