Ubuntu is already the dominant cloud operating system. With the release 
of Ubuntu 15.10, Wily Werewolf, Canonical's Ubuntu is ready to take an 
even bigger bite.


Canonical's new Ubuntu release, Wily Werewolf, is ready to snap up your 
cloud and server work.
First, Canonical has bundled its new Ubuntu OpenStack cloud deployer and 
management tool: OpenStack Autopilot with this release. OpenStack is not 
easy to install. Companies such as Mirantis and Red Hat have also worked 
hard on making it simple to install the popular open-source cloud.

While Autopilot runs side by side with Ubuntu 15.10, it deploys, manages 
and scales Ubuntu 14.04 LTS and Ubuntu OpenStack Kilo. It has been 
designed to fully support in-place upgrades between releases.

"One of the biggest issues organisations using OpenStack face is how to 
scale their clouds in line with expansion without having to employ 
expensive cloud architects to manually re-design them. Autopilot offers 
enterprises a smart, way to scale their cloud technically and 
financially," said Shawn Madden, Autopilot Product Manager at Canonical 
in a statement. "We have built Autopilot to deliver superior scale and 
economics in a simple to use package."

If your company does have OpenStack expertise, then you might want to 
try Ubuntu 15.04's built-in OpenStack: the brand-new OpenStack 
distribution Liberty.

This cloud distribution has three key themes of Manageability, 
Scalability and Extensibility:

Manageability

Common library adoption
Improved configuration management
More granular Neutron security settings with role-based access control 
(RBAC) support
Scalability

Initial version of Nova Cells V2 implementation to improve of single 
region large scale OpenStack clouds
Neutron, Nova and Cinder scale improvements
Extensibility

Support for OpenStack as the integration engine with 'Big tent' model of 
ancillary project identification
Support for containers with debut of LXD Nova driver to enable workloads 
to be deployed as LXC containers

First release of Magnum with container framework support for integration 
of Kubernetes, Swarm and Mesos.

OpenStack Liberty is also available for Ubuntu 14.04 LTS via the Ubuntu 
Cloud Archive.

On the server side, LXD, Ubuntu's machine container hypervisor, is now 
included in Ubuntu by default. With it, Ubuntu servers can easily host 
hundreds of other Linux guest containers.

According to Canonical, "LXD provides all of the key features expected 
of a modern hypervisor -- image management, snapshots, live migration, 
Fan overlay networking, IPv4 and IPv6 support, and an industry leading 
security profile." In addition to these features, LXD also provides an 
open, RESTful API. This can be used to create tools that can start, 
stop, clone, and live migrate LXD containers. The RESTful API is still 
beta. The first example, a OpenStack nova-compute-lxd driver, is now 
available as a Tech Preview in Ubuntu OpenStack Liberty.

This release also includes an improved version of the Ubuntu's Metal as 
a Service (MaaS) platform. This can be used to install Linux or Windows 
operating system onto physical hardware. In 15.10, MaaS's web interface 
has been redesigned, and can be used on both PCs and mobile devices..

The Wiley Werewolf server is built on the v4.2 Linux kernel. This kernel 
brings Advanced Configuration and Power Interface (ACPI) support for ARM 
processors, Linux Security Module (LCM) Stacking, and the new thermal 
Power Allocator governor to Ubuntu.

On top of this Canonical has added fan networking for container network 
address space expansion. As an experiment, the Werewolf also introduces 
a Data Plane Development Kit (DPDK) faster packet processing in 
network-heavy applications. DPDK is a set of libraries and drivers for 
fast packet processing. It's currently being tested and deployed by 
telecoms companies in high-volume OpenStack deployments.

The Ubuntu desktop may get the attention, but with these advances, 
chances are you're more likely to use Ubuntu, hidden behind the scenes, 
on clouds and servers. This wolf is on the prowl.
