Latest Ubuntu offers businesses added cloud features and sleek new desktop interface


on 28 April 2011

This article was last updated 9 years ago.

Canonical today announced availability on April 28 of the Ubuntu 11.04 suite of products for businesses. Spanning corporate and developer desktops, servers and the leading open-source cloud implementation, Ubuntu 11.04 offers businesses of all sizes an open-source alternative.

“Ubuntu 11.04 offers exciting opportunities for businesses to improve the reliability, security and manageability of desktop, cloud and server deployments, challenging the traditional license or subscription fee model and embracing open-source technology,” said Jane Silber, CEO of Canonical. “This release comes at a time of accelerating corporate adoption of Ubuntu and delivers a range of improvements specifically relevant to the corporate environment.”

Ubuntu 11.04 for the cloud

Ubuntu Server 11.04 – already the industry-standard open-source cloud OS – improves on its built-in cloud infrastructure (Ubuntu Enterprise Cloud based on Eucalyptus), providing an easy-to-use, affordable alternative for companies looking to build private clouds compatible with Amazon’s public cloud infrastructure.

Ubuntu Server 11.04 adds the OpenStack “Cactus” release as a technology preview, downloadable through the Ubuntu software repositories. Ubuntu features the most tightly integrated implementation of OpenStack on an operating system available today, giving companies evaluating OpenStack a unique opportunity to assess the latest release.

Ubuntu Server 11.04 will be fully available on Amazon’s EC2 on the day of release; users can trial Ubuntu Server 11.04 on the Amazon cloud on April 28 for an hour for free. Simply follow the links on

Ubuntu 11.04 for the corporate desktop

For desktop deployments, Ubuntu 11.04 offers a choice of Unity– a new, simplified and modern interface — or the option to retain the “classic” Ubuntu interface. Unity makes its first appearance in this release and will be the interface of Ubuntu for all users in the next long-term support (LTS) release in April 2012. Desktop deployments of Ubuntu 10.04 LTS can test what’s coming in the next LTS release while retaining the option of the current, “classic” desktop experience.

Ubuntu 11.04 for servers

Ubuntu Server supports the latest server hardware, with a list of certified systems available at Ubuntu 11.04 certifications will be published there as they pass testing. Certifications enable businesses to make informed decisions when choosing hardware and decide if point release upgrade is needed when purchasing new server hardware for use with Ubuntu.
