Even in 2018, if we ask many people what they know about Ubuntu, they’ll tell we it’s a desktop Linux. Oh, yet there’s so, so many some-more to Canonical‘s Ubuntu than that, and in a latest long-term support (LTS) release, Ubuntu 18.04 LTS, that unequivocally shows up.

In a discussion call interview, Mark Shuttleworth, Canonical’s CEO and Ubuntu’s founder, said, “Most open cloud instances — Azure, AWS, Oracle, and so on — are Ubuntu. To softened support Ubuntu, 18.04 facilities improvements in network and storage and softened foot time optimization so that Ubuntu instances can ramp adult faster with demand. In addition, Canonical has been operative with NVIDIA to urge a open cloud General Purpose GPU (GPGPU) support.”

Shuttleworth added: “Multi-cloud operations are a new normal. Boot-time and performance-optimised images of Ubuntu 18.04 LTS on each vital open cloud make it a fastest and many fit OS for cloud computing, generally for storage and discriminate complete tasks like appurtenance learning.”

NVIDIA GPGPU hardware acceleration is built into Ubuntu 18.04 LTS cloud images and Canonical’s OpenStack and Kubernetes distributions for on-premise unclothed steel operations, ancillary Kubeflow, and appurtenance training (ML) and AI workflows.

This has lead Canonical to operative closely with Google, IBM, and NVIDIA to urge Ubuntu’s ML support. Shuttleworth privately mentioned a work with Google on Kubeflow as an example. This is a new open-source plan dedicated to creation regulating ML stacks on Kubernetes easy, fast, and extensible.

Kubeflow, a Google proceed to TensorFlow on Kubernetes, and a operation of CI/CD collection are integrated in Canonical Kubernetes and aligned with Google GKE for on-premise and on-cloud AI development.

“Having an OS that is tuned for modernized workloads such as AI and ML is vicious to a high quickness team” combined David Aronchick, product manager of Cloud AI during Google. “With a recover of Ubuntu 18.04 LTS and Canonical’s collaborations to a Kubeflow project, Canonical has supposing both a informed and rarely performant handling complement that works everywhere. Whether on-premise or in a cloud, module engineers and information scientists can use collection they are already informed … and severely accelerate their ability to broach value for their customers.”

Canonical is also stability to support a OpenStack Infrastructure-as-a-Service (IaaS) cloud.

Shuttleworth claimed Canonical OpenStack delivers private cloud with poignant assets over VMware with a modern, developer-friendly Application Programming Interface (API). With built-in support for NFV and GPGPUs, a Canonical OpenStack charity has turn a anxiety cloud for digital mutation workloads. Today, Ubuntu is during a heart of a world’s largest OpenStack clouds, both open and private, in pivotal sectors such as finance, media, retail, and telecommunications.

Shuttleworth slammed VMware: “VMware is expensive. OpenStack is replacing it.”

In addition, Canonical’s Distribution of Kubernetes (CDK) runs on open clouds, VMware, OpenStack, and unclothed metal. It delivers a latest upstream version, now Kubernetes 1.10. Many Canonical partners broach their solutions on CDK, such as Rancher 2.0, a renouned enclosure government program.

Shuttleworth continued, “We consider Kubernetes is a commodity. Our pristine Kubernetes is delivered as a giveaway use on tip of VMs. It’s a simplest and many cost fit solution, and with it, we can scale Kubernetes from desktop to shelve and out to a open cloud.”

This is in contrast, he said, to Red Hat, that has integrated Kubernetes into OpenShift, Red Hat’s Platform-as-a-Service (PaaS). This is true, with a release of Red Hat Enterprise Linux (RHEL) 7.5. Red Hat announced, “With Red Hat Enterprise Linux 7.5, we’re … totally deprecating a Kubernetes RPMs and enclosure image.” If we wish to use Kubernetes in production, “We suggest that business evaluate Red Hat OpenShift for a entirely upheld enclosure height formed on Kubernetes.”

With Ubuntu 18.04, CDL also supports GPGPU acceleration of workloads regulating a NVIDIA DevicePlugin. Applications built and tested with Kubeflow and CDK are ideally transportable to Google Cloud.

Developers on Ubuntu can emanate applications on their workstations, exam them on private bare-metal Kubernetes with CDK, and run them opposite immeasurable information sets on Google’s GKE. The ensuing models and deduction engines can be delivered to Ubuntu inclination during a corner of a network, formulating a ideal tube for appurtenance training from workstation to shelve to cloud and device.

Canonical is aslo regulating LXD, it’s enclosure hypervisor, to ‘lift-and-shift’ bequest workloads into containers for opening and density. LXD does this by providing ‘machine container,’ that act like practical machines. They can enclose a full Linux guest handling complement such as Ubuntu, RHEL, or CentOS. This provides a normal administration sourroundings for bequest applications, that run, Canonical claims, during unclothed steel speeds with no hypervisor latency.

As Shuttleworth explained, “Enterprises are realizing bequest apps aren’t gentle in a Kubernetes world. LXD, a complement enclosure that behaves like a VM, lends itself good for normal applications.” He combined there are “tools accessible to pierce bequest apps from hardware and practical machines to LXD. For example, we can run comparison RHEL instances but a Intel Meltdown and Spectre rags on LXD on Ubuntu 18.04, with a patches.” Shuttleworth concluded, “80 percent of bequest apps can run in LXD. It all depends on a app’s need for a specific kernel. If they don’t need a specific Linux kernel, they can run in LXD.”

Thinking of Legacy with a collateral L applications, Ubuntu 18.04 also supports IBM mainframes. “Canonical and IBM have been operative closely together to offer cloud solutions with Ubuntu on IBM LinuxONE and IBM Z,” pronounced Michael Desens, IBM’s VP of Offering Management, IBM Z, and LinuxONE.

Don’t let all this speak about clouds and Kubernetes dope you, though. Canonical is still ancillary a desktop. The new Ubuntu 18.04 LTS comes with a default GNOME desktop as a deputy for a Unity desktop. It also natively supports a KDE, MATE, and Budgie desktops.

Shuttleworth also boasted of a flourishing recognition of a snap package manager system. Snaps, that started in Ubuntu Touch, are now a Linux distro-agnostic upstream module smoothness system. Canonical claims there are some-more than 3,000 snaps published and millions installed, including central releases from Spotify, Skype, Slack, and Firefox. With snaps, publishers can broach module updates directly and confidence is confirmed with extended heart siege and complement use mediation.

“Snaps enables us to entrance some-more Linux users and opens a marketplace for us to accommodate some-more distributions,” pronounced Jonáš Tajrych, comparison module operative of Microsoft’s Skype. Snaps reduced, he said, “the complexity and time of progressing several packages opposite mixed distributions. In addition, we wish a users to consistently knowledge a latest and biggest chronicle of Skype and a involuntary refurbish underline allows us to seamlessly broach this to them. It’s such a earnest format and an item for developers to assistance emanate unification.”

If we wish a “just a basics” Linux desktop, Canonical is also providing a new minimal desktop. This provides usually a core desktop and browser. In businesses, a minimal desktop can offer as a bottom for tradition desktop images with only a applications we wish and a smaller conflict surface.

And, stability on with desktops, Ubuntu will run softened than ever… with a Windows desktop.

New Hyper-V-optimised images grown in partnership with Microsoft raise a practical appurtenance knowledge of Ubuntu in Windows. “In a arriving OS recover this spring, Hyper-V’s Quick Create VM Gallery will now embody an picture for a latest Ubuntu 18.04 LTS, strictly hammered true from Canonical,” pronounced Craig Wilhite, module manager during Microsoft. “This Ubuntu VM picture will come pre-configured to offer clipboard functionality, expostulate redirection, energetic resizing of VM console window, and many more, as we demeanour to yield a good Hyper-V customer VM knowledge for Linux on Windows.”

So, while many of we might still be regulating a Ubuntu desktop, Canonical is creation it really transparent that Ubuntu has a incomparable purpose to play on clouds with containers and even with an aged rival: Microsoft.
