Juju logo

Juju — application modeling

With the option of a command line or browser-based interface, Juju enables you to design and deploy entire workloads in just a few clicks. It works on public clouds like AWS and Microsoft Azure, private clouds built on OpenStack and even directly on bare metal, via MAAS.

Maas logo

MAAS — bare metal provisioning

MAAS is a time-saving provisioning system which makes it quick and easy to set up the physical hardware to deploy complex services, like Ubuntu’s OpenStack cloud infrastructure. Just plug in your servers, connect them to the network and let MAAS do the rest.

LXD — system containers

LXD, the Linux container hypervisor, merges the speed and density of containers with the manageability and security of traditional virtual machines. Economics are directly tied to density, and no other virtualisation technology is as fast or dense as LXD.

Built for big data and cloud

Speed and simplicity, on bare metal or in the cloud

With its new rapid deployment tools, Ubuntu significantly speeds up the installation of server instances on bare metal. And our service orchestration tool, Juju, makes deploying big data services surprisingly simple — on bare metal or in the cloud. That’s why vendors like 10gen, Cloudera, Couchbase, DataStax, Hortonworks, LexisNexis and Map-R partner with us.

The fast track to virtualisation and containers

Ready to boost efficiencies and reduce costs? Virtualise your servers with Ubuntu Server, KVM and LXD. When you use a secure, lean version of Ubuntu as a guest operating system for your application, you can create virtual machines and machine containers in seconds. KVM, LXD, Xen, VMware, Vagrant, VirtualBox, and Docker are all first class experiences with Ubuntu Server. Ubuntu Server now supports KVM on ARM and IBM POWER8 architectures.

Canonical believes in choice — that's why we support an open ecosystem of operating system intercompatibility. By providing choice, users of Ubuntu for both servers and clouds are empowered to succeed with any workload. We encourage others to do the same and offer support for all (currently supported) versions of Ubuntu Server running on other virtualisation platforms, including KVM on other commercially available Linux distributions, VMware vSphere, and Microsoft Hyper‑V.
