Ubuntu on the Cloud with Virtualization

Ubuntu 8.10 Server Edition is a terrific milestone that underlines the value in our twin track release strategy

Canonical announced the upcoming availability of Ubuntu 8.10 Server Edition for free download on 30 October. In related news Canonical also announced the simultaneous release of Ubuntu 8.10 Desktop Edition.

Ubuntu 8.10 Server Edition will be maintained for 18 months and adds significant enhancements in virtualisation, Java development and system management. This continues the project's commitment to serve the needs of those users for whom innovation and performance are vital.

Ubuntu 8.10 Server Edition is a terrific milestone that underlines the value in our twin track release strategy.

In tandem with the Ubuntu 8.04 Long Term Support (LTS) release, maintained for another four and a half years, Ubuntu offers users a real choice between the stability and longevity of the LTS releases and the opportunity to try the latest innovations of the Ubuntu 8.10 release. No other Linux or proprietary server OS supports this level of choice.

"Ubuntu 8.10 Server Edition is a terrific milestone that underlines the value in our twin track release strategy," said Jane Silber, COO of Canonical. "The server edition embraces cloud computing, virtualization, mail server enhancements, Java development and deployment as well as a range of services to help system admininstrators and developers. Our six-monthly release cycle allows us to get these features in front of users faster continuing to make Ubuntu the best option for innovative organisations."

New to Ubuntu 8.10 Server Edition
Virtualization - Building on the Just Enough Operating System (JeOS) version launched last year, Ubuntu 8.10 ships with a Virtual Machine builder. It allows complete Virtual Machines to be built from the command line in less than five minutes. Developers and system administrators can script the creation of custom virtual images. Vm-builder provides a key component to a dynamic provisioning process for businesses using virtualisation environments.

JeOS has been merged into the Server CD and is now available as an option at installation time. Ubuntu 8.10 officially supports running as a paravirtualized guest on Xen hypervisors. KVM has also been updated to allow more flexible memory management. Administrators can reduce or increase the memory allocated to any virtual machine without having to reboot it.

Complete JavaTM Stack
Apache Tomcat 6.0 and OpenJDK are now fully supported options that make Ubuntu a great choice for developing and deploying Java applications in production environments.

Enhanced Mail Server Capabilities

ClamAV and SpamAssassin are now available from the main repository providing a supported solution for spam detection and virus filtering for mail infrastructures built on Ubuntu Server.

Improved RAID Support
Ubuntu 8.10 provides support for SATA "software" RAID controllers via DMRaid. Booting from a degraded RAID array is now configurable by the system administrator.

Encrypted Private Directory
Administrators can now easily set-up an Ubuntu system to provide encrypted private directories which are automatically mounted when users login locally or via ssh. Sensitive data is kept secure even if the system is stolen.

Hardening the Packages
The tool chain used to compile Ubuntu has been updated to include even more security features such as glibc function call fortification. Bugs in applications are even harder to be turned into exploitable vulnerabilities.

Uncomplicated Firewall is Getting Even Simpler
The Uncomplicated Firewall makes it easier to manage a host firewall thanks to the addition of application profiles. Common services such as apache, bind9, cups, dovecot, openssh, postfix or samba declare which ports they use so that the administrator only enables a network service rather than a set of ports.

Landscape Client Bundled within Ubuntu
Landscape client provides a free reporting function at each login. Key information such as system statistics is added to the "message of the day" that is displayed at login (motd). Any type of metric can be gathered simply by writing plugins for Landscape client.

Landscape is Canonical's lightweight system management tool for Ubuntu systems that allows automated deployment and monitoring. Full activation of the client for landscape customers is now available within the installer.

"Matrix is an ambitious open standard and implementation that's set up to break down the fragmentation problems that exist in IP messaging and VoIP communication," explained John Woolf, Technical Evangelist at Matrix, in this interview at @ThingsExpo, held Nov 4–6, 2014, at the Santa Clara Convention Center in Santa Clara, CA.
Nowadays, a large number of sensors and devices are connected to the network. Leading-edge IoT technologies integrate various types of sensor data to create a new value for several business decision scenarios. The transparent cloud is a model of a new IoT emergence service platform. Many service providers store and access various types of sensor data in order to create and find out new business values by integrating such data.
Too often with compelling new technologies market participants become overly enamored with that attractiveness of the technology and neglect underlying business drivers. This tendency, what some call the “newest shiny object syndrome,” is understandable given that virtually all of us are heavily engaged in technology. But it is also mistaken. Without concrete business cases driving its deployment, IoT, like many other technologies before it, will fade into obscurity.
