One of the great strengths of Canonical's Ubuntu Linux is its Juju orchestration technology, which is advancing now in a number of different ways.
Juju first debuted in Ubuntu 11.10, the "Oneiric Ocelot," back in October of 2011. The word "juju" is a word meaning magic in the African language from which the name Ubuntu itself was derived. The promise of Juju is easier application and service deployment, which is enabled by way of a number of Juju components.
One of the fastest ways to benefit from Juju is by way of the Juju Quickstart.
"Juju Quickstart helps both new and experienced users quickly start working with Juju and the Juju GUI, whether they've never installed Juju or they have an existing Juju environment running," Ubuntu developer Francesco Banconi wrote in his release announcement for Juju Quickstart 1.6.0.
The new Juju Quickstart 1.6.0 was released on January 14, providing users with enhanced capabilities that make it easier to deploy applications to target environments. The session window for selecting an environment has been improved as well, and users can now manage imported environments.
Juju can be run from the command-line interface, but it can also run in a GUI thanks to the Juju GUI tool. Ubuntu developers released the Juju GUI 1.3.0 update at the same time as Juju 1.6.0, which provides a speed boost to users. Juju GUI 1.3.0 will now support multiple users as well.
"With the upcoming feature in Juju Core 1.21 of multiple users, we’ve added the ability to log in as any of the users that are attached to your environment," Ubuntu developer Madison Scott-Clary wrote in the release announcement.
The third update this week from Ubuntu for Juju is an update of jujucharms.com. Juju leverages "charms" as manifests that help define a service or application orchestration procedure. The new update is a bug fix milestone that cleans up duplicate search results and improved bundle visualizations.
The Juju updates are all rolling out as Ubunutu developers continue to work on the next major platform release. Ubuntu 15.04 "the Vivid Vervet" is currently set for release on April 23.
