The next version of Canonical's Ubuntu Server, version 11.04, due out April 28, will set the stage for the open-source operating system's greater usage in the enterprise cloud, company officials said.

"People running private clouds will start really scaling those over the next several years. So what we care about is the ability to expand as customers deploy more and more servers into the cloud," said Steve George, Canonical's vice president of business development.

According to IDG News Service, Canonical develops LTS [long-term support] server releases for organizations that need ultra-stable and highly supported versions of the OS. The company supports these versions for five years, in contrast to the typical two-year support cycle of most server releases, including this one. The next LTS release, 12.04, is due in April 2012.

“The version to be released next week, which was code-named Natty Narwhal during development, updates a number of packages essential for cloud deployments,” George said.

This release includes version 2.0.2 of the Eucalyptus cloud software, upgraded from version 1.7 that was used with the last release. The release also includes expanded support for libvirt - a collection of software for managing virtual machines - and KVM (Kernel-based Virtualization), which is Canonical's default virtualization platform.

Canonical also plans to post a version of this server software on Amazon's EC2 (Elastic Cloud Compute) that has been customized for HPC (high-performance computing) duties, which tend to be used by scientific researchers.
