Performance and versatility
Agile, secure, deploy-anywhere technology for fast-moving companies
It doesn't matter whether you want to deploy a NoSQL database, web farm or cloud. Certified by leading hardware OEMs and with comprehensive deployment tools, so you can get the most from your infrastructure.
Our regular release cycle means access to the latest and most performant open source. A lean initial installation and integrated deployment and application modelling technologies make Ubuntu Server a great solution for simple deployment and management at scale.
A release schedule you can depend on
Stay up-to-date with regular updates and upgrades
Long-term support (LTS) releases of Ubuntu Server receive security updates by Canonical for five years by default. Every six months, interim releases bring new features, while hardware enablement updates add support for the latest machines to all supported LTS releases. All Ubuntu Advantage for Infrastructure subscriptions include Extended Security Maintenance (ESM) increasing the support life-cycle to up to 10 years.
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 clouds implementation and the platform of choice of developers according to the 2020 HackerEarth Developer Survey.
Juju — 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 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 — 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.
