Two years after the previous Long Term Support (LTS) release of Ubuntu – 14.04 Trusty Tahr – it’s time to move on to version 16.04, Xenial Xerus. This LTS was released on the 20th of April 2016 by Canonical and is now available in our Fuga Glance image library.
While new Ubuntu Desktop and Server releases appear every six months, LTS versions are released every two years, and are supported by Canonical for five years after release. This means that they constitute a stable platform for deploying production systems, and receive security updates and critical bugfixes for a substantial window of time. 16.04 will continue to be updated until April of 2021.
Let’s take a look at the most important new features in Ubuntu 16.04 starting with “Snap”. This new application format is designed to work side-by-side with traditional deb packages. Snap applications are completely isolated from the rest of the system, which has several advantages:
- It cannot interact with other files on the system
- It is inherently secure against malicious software
- It helps to ensure that it is compatible with existing software
The other main feature of the 16.04 release is support for the LXD pure-container hypervisor. LXD is capable of 14 times the workload density and significantly higher performance compared to traditional virtualization technologies for each guest device connect to the Fuga cloud platform.
Besides that, Ubuntu 16.04 also supports the ZFS-on-Linux software, which functions as a file system and volume manager with a wide array of data management tools. Alternatively, Ubuntu 16.04 LTS also supports the CephFS file system, which can better handle large-scale enterprise storage devices and cluster computing.
Ubuntu 16.04 is now available in our Fuga Glance image library.
