Canonical's Saucy Salamander gives Ubuntu some speed

The new version of Ubuntu will also come with the latest edition of OpenStack

Canonical continues to make the Ubuntu server edition speedier and more versatile in cloud environments.

The newest version of the Linux distribution, which will be ready for downloading October 17, comes with a faster installer as well as an updated lightweight container technology that can clone new environments more quickly.

The performance improvements in Ubuntu 13.10, code-named Saucy Salamander, are "part of the plan to ensure that Ubuntu becomes the best environment for developing, testing, and running production services in a cloud. Speed is one of those things people measure," said Mark Baker, Ubuntu server and cloud product manager.

Ubuntu 13.10 also comes with the latest edition of the OpenStack cloud platform, code-named Havana, which is also due to be released October 17.

The new Ubuntu will come with a fresh installer that is particularly efficient at loading the distribution over the network on bare metal servers, or as virtual machines in a cloud. The software can reduce the amount of time needed to install Ubuntu in a cloud to less than three minutes in many cases.

"We use a very slim cloud image that can be copied across the network very quickly," Baker said. "Rather than pulling over individual packages and building them in the traditional method, the installer pulls a pre-built image for the [cloud's] hypervisor."

Ubuntu 13.10 also includes improved support for Linux Containers (LXC), a container technology that provides a way to run multiple operating environments on a single machine.

"Containers are lighter than fully virtualized environments. If you want to make better uses of resources, you could run more containers on a machine than virtual machines (VMs)," Baker said. A container can be copied more rapidly than a full VM, according to Baker.

A single developer working on a laptop should consider using containers rather than a full VM because containers consume less resources. Multiple containers share certain resources, such as the operating system kernel, while maintaining full isolation from each other.

Ubuntu 13.10 will include OpenStack Havana, the latest version of the open source cloud platform. Havana comes with Heat, a new orchestration engine for managing complex OpenStack jobs, as well as the new Swift object storage engine.

Another important feature for the new version of OpenStack is that it will support virtualization hypervisors other than its natively supported open source KVM (kernel virtual machine). In particular, it can work with VMware's ESX hypervisor through the Nova plug-in.
