Ubuntu Server Edition


Ubuntu Server Edition

Ubuntu also offers its operating system in a server edition. The Ubuntu 10.04 Long Term Support (LTS) release is scheduled to receive continued updates until April 2015. Starting with 12.04 the support of the LTS deskop variants has been extended to match the 5 years of the server variant. Long term support include updates to support new features of the latest computing hardware, security patches and updates to the 'Ubuntu stack' (cloud computing infrastructure).[77]

Ubuntu 10.04 Server Edition can also run on VMware ESX Server, Oracle's VirtualBox and VM, Citrix Systems XenServer hypervisors, as well as Kernel-based Virtual Machine. Ubuntu uses AppArmor security module for the Linux kernel which is turned on by default on key software packages, and the firewall is extended to common services used by the operating system. The home and Private directories are also encrypted. The 10.04 server version includes MySQL 5.1, Tomcat 6, OpenJDK 6, Samba 3.4, Nagios 3, PHP 5.3, Python 2.6. Many of its services only take 30 minutes to configure.[77]
Ubuntu 10.04 LTS Server Edition supports two major architectures: Intel x86 and AMD64. The server edition provides features such as file/print services, web hosting, email hosting, etc. There are a few differences between the Ubuntu Server Edition and the Ubuntu Desktop Edition although both use the same apt repositories. The main difference between the two editions is the lack of a default installation of a X window environment in the server edition, although GUIs can be installed like GNOME/Unity (Ubuntu 11.04), KDE (Kubuntu 11.04), XFCE, (Xubuntu 11.04), as well as more resource-economical GUIs such as Fluxbox, Openbox and Blackbox. Kernel versions also differ. The server edition uses a screen mode character-based interface for the installation, instead of a graphical installation process.
Ubuntu Server is also distributed free of charge. Users can choose to pay for consulting and technical support. Annual support contract with 9x5 business hour support is about $750 per server, and a contract covering 24x7 over a year costs $1,200.[77]
