Lower your cost of ownership
Predictable life cycle and maintenance policy
Ubuntu Server Edition is free, and always will be. There is
no ‘for pay’ edition that contains extras. We know that
license fees are only the starting point in making a TCO
argument in your business, therefore, consider the merits of
Ubuntu Server Edition:
Our product life cycle ensures that you can perform
upgrades of your systems, in place, time after time, at
the pace you choose, without compromising the work you
have put in setting them up.
Easy to manage
– installation, startup, shutdown,
service initialisation and package management.
Built for purpose
– no bloatware and no extraneous
applications clogging up what you really want to do–run the
services that run your business.

maximising your server efficiency or simply running lean
services across your network, Ubuntu is a great partner in
the drive to improve efficiency.
Ubuntu Server Edition has a dual release cycle
•
Every 6 months a version is released that contains the
latest packages and updates. This is maintained for 18
months from release with an upgrade path to the next 6
month release version.
Security
– the greatest risks to your business are
eliminated. Continuous updates respond to the changing
landscape of risk on an already hard to hack distribution.

For greater robustness and easier planning, every
2 years a Long Term Support (LTS) version is released that
is maintained for 5 years. This is a target platform for ISVs
looking to build solutions on Ubuntu and also for larger
deployments in need of a more stable release.

Virtualization
Canonical Landscape:
System Management for Ubuntu
Ubuntu Server Edition offers a variety of virtualization
technologies for use as a host or guest operating system.
There are open source and proprietary solutions to
meet every need. KVM (Kernel Virtual Machine) is our
open source virtualization solution, it’s effi cient and
comes with a suite of management tools. Additionally,
we have established premier relationships with VMware
and Parallels to offer a range of options to meet every
requirement.
Deploying applications and security updates to multiple
machines is a critical component in effective systems
management. Landscape makes Ubuntu systems
management simple, enabling you to manage multiple
Ubuntu machines through a single web interface. Simply
register a machine in Landscape and you can immediately
start managing application, system and user resources.
Storage Area Network
Ubuntu Server Edition brings the power of inexpensive
shared storage to your servers. More and more
organisations rely on the throughput of Gigabit Ethernet
to build up their SAN (Storage Area Network) for data
or virtual machine storage. Using relatively inexpensive
hardware, the performance can be quite amazing.
Two key storage technologies feature in Ubuntu Server
Edition: iSCSI and DRBD. They enable administrators
to attach network storage to a server. These low level
protocols can be used in conjunction with a variety of
fi le systems and high availability capabilities to set-up
scalable and robust server confi gurations.
Processor technologies
Ubuntu Server Edition is optimised for 32 or 64-bit multi-
core processors. The Kernel team is working closely
with Intel and AMD to implement the latest features the
processors allow, and integrate the latest drivers the
