Infrastructure and applications foundation
From public clouds to data centres to devices
Ubuntu is the most popular guest operating system on public clouds, the foundation for private cloud implementation and the platform of choice of developers according to the 2020 HackerEarth Developer Survey.
Multi-cloud orchestration
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 — bare metal provisioning
MAAS is a time-saving provisioning system that 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 — machine containers
Economics are directly tied to compute density. LXD, the Linux container hypervisor, merges the speed and density of containers with the manageability and security of traditional virtual machines.
Ubuntu Pro
Ubuntu Pro offers a single, per-node packaging of the most comprehensive software, hardening and security in the industry. With the Base OS, OpenStack, Kubernetes and Applications security maintanance included, Ubuntu Pro delivers everything you need to future-proof your data centre.
Furthermore, you can add support for the Base OS, Infrastructure and Applications.
