This article is about what Ubuntu 13.10 has improved. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

The Linux server version of Ubuntu 13.10 has now been officially released, bringing new cloud management and deployment capabilities to a wide range of administrators. Ubuntu 13.10, codenamed "SSaucy Salamander", will form an alliance with the OpenStack cloud platform to welcome the landmark new version of OpenStack Havana, which was released earlier this week.

Mark Baker, Ubuntu server and cloud product manager at Canonical, pointed out in an interview that the Juju system in Ubuntu 13.10 has undergone a significant evolution. Juju***, which appeared in Ubuntu version 11.10 in 2010, is a technology that specializes in managing server and cloud deployment processes.

"Juju has a 'charms' mechanism to define its services, some of the objects it can connect to, and how it is installed," Baker explained.

He also added that administrators will frequently use scripts for Juju charms deployment. In Ubuntu 13.10, the binding concept of Juju is also included to provide administrators with the ability to use more deployment script options. The Juju binding can also be shared, which is used to define a series of charms.

OpenStack Havana

Ubuntu 13.10 Server also offers a new version of OpenStack Havana. Havana has its own cloud process system, called "Heat", but only as an alternative. Baker does not see Heat as an alternative to Ubuntu's existing Juju.

"Heat is a server process system designed specifically for OpenStack; by contrast, although Juju belongs to the same server process system, it mainly points to a variety of cloud mechanisms and environments," Baker told us. "We will rest assured to watch the development of Heat and see if Heat API can gradually deliver a better performance than Juju in driving applications-which will also determine our next step."

Joint positioning

Before Ubuntu 13.10, every new service launched by Juju required a new set of virtual machine instances to be stripped to provide a match. With the help of the new feature "federated location", administrators can now run multiple services in the same virtual machine instance.

"people have been able to achieve similar functionality before, but it needs to be done entirely manually," Baker said.

Another big new feature in Ubuntu 13.10 is that the Juju Inspector function now works in parallel with Juju GUI.

"in the past, we could only judge the operation simply by the lights-the green light means normal and the red light means failure," says Mr Baker. "now it has evolved to know whether the service is running, the current number of connections and other basic indicators through proximity."

LXC

Ubuntu 13.10 now also provides expanded Linux container (LXC) support. Baker says performance has been significantly improved with the help of the new installation of LXC. The system can now use containers to clone user data faster and more efficiently.

Baker pointed out that compared with the traditional hypervisor-based virtual machine system, the container mechanism has increasingly become a virtualization alternative accepted by the majority of users.
