FREMONT, CA: The stable version of Ubuntu 15.04 (Vivid Vervet) is now ready for release. The latest operating system comes with a bagful of innovative solutions in the form of LXD, OpenStack Kilo, and Snappy Ubuntu Core. Developers stand to go gain with support for more new platforms focused on mobility. One operating system will cater to innovations across the desktop, mobile, cloud, and IoT ecosystem.

Introducing LXD
The Linux Container Daemon (LXD) is Canonical’s hypervisor for containers. LXD acts as the server for Linux containers (LXCs). Developers can now use LXD on all the machines they are working with and make the most of LXCs. The striking feature of LXD is that it is designed exclusively for Linux. So users will be able to run LXD on Ubuntu as well as run instances of other Linux variants such as RHEL, CentOS, Suse, Debian, Ubuntu, and the likes. To run Windows, the user would still have to use a traditional hypervisor like KVM or ESX.

Features and benefits of LXD include:

Maximum density of guests per host; rapid provisioning; instant guest boot; support for REST API; comprehensive operating system (OS) functionality within containers; tight integration with remote image services; extensible storage and networking; ease in sharing and management of hardware resources; simplified monitoring; greater security in the form of AppArmor, user namespaces, SECCOMP.

Snappy Ubuntu Core
As a lightweight transactional updated version of Ubuntu, Snappy Ubuntu Core forms a perfect system for large-scale cloud container deployments. It comes with a minimal server image with regular Ubuntu libraries. It is fast, more reliable, and it enables Snappy apps and Ubuntu Core itself to be upgraded automatically while keeping the provision for roll back on an ad hoc basis.

Developers can build snappy Ubuntu apps by just bundling all the files in a single package and publish which can then be downloaded instantly by users. Ubuntu Core is already being used in drones, robots, IoT home hubs, industry gateways, network switches, and mobile base stations.

Features of Snappy Ubuntu Core:

OS and application files are maintained as distinct read-only images; signatures and fingerprints ensure greater security; transactional, image-based delta updates for the system and application.  

Ubuntu OpenStack Kilo
The OpenStack Neutron capabilities are extended through Kilo to include Distributed Virtual Routing so that Neutron can be scaled more efficiently. Enterprises users having multiple OpenStack implementations can achieve more effective identity management while simplifying the adoption of hybrid cloud adoption.

For Developers
Canonical has come with an updated Ubuntu Developer Tools Centre called ‘Ubuntu Make’ supporting 14 new platforms for developers of mobile apps, web applications and games. The new platforms include: latest editions of Android NDK and Android Studio; IDEA (ultimate and community editions); pycharm; webstorm; rubymine; phpstorm; eclipse; firefox developer edition; and Stencyl game development platform.

The new Ubuntu OS termed as Vivid Vervet also comes with updates for Office tools in the form of LibreOffice 4.4 that has improved change tracking to Writer, enhanced mail merge performance, and more. This innovative lightweight OS also happens to be the base for the Ubuntu Phone and Canonical says it is committed to deliver updates to the mobile platform in coming weeks.
