The Raspberry Pi 2, 3, and 4 join a very long list of x86 and ARM devices certified with Ubuntu, the operating system (OS) best known for its public cloud and desktop offerings. Dell, HP and Lenovo all certify PCs with Ubuntu Desktop, which is also the most widely used OS on the AWS, Microsoft Azure, Google, IBM and Oracle clouds.
Ubuntu 20.10 also includes LXD 4.6 and MicroK8s 1.19 for resilient micro clouds, small clusters of servers providing VMs and Kubernetes on demand at the edge, for remote office, branch office, warehouse and distribution oriented infrastructure.
Ubuntu Desktop 20.10
On top of Raspberry Pi desktop support, Ubuntu 20.10 includes GNOME 3.38, which tweaks the apps grid, removes the frequents tab and allows apps to be ordered and organised however users prefer. The battery percentage display toggle has been exposed in power settings, private WiFi hotspots can be shared using uniquely generated QR codes and a restart option has been added to the status menu next to logout/power off.
The 20.10 desktop sees added support for Ubuntu Certified devices. More Ubuntu workstations now receive biometric identification support out of the box. 2-in-1 devices with on screen keyboards are now fully supported enabling an improved Ubuntu experience on devices including the Dell XPS 2-in-1 and Lenovo Yoga.
Raspberry Pi models with 4GB or 8GB RAM gain full support for the Ubuntu Desktop. “From the classic Raspberry Pi board to the industrial grade Compute Module, this first step to an Ubuntu LTS on Raspberry Pi with long term support and security updates matches our commitment to widen access to the very best computing and open source capabilities,” said Eben Upton, CEO of Raspberry Pi Trading.
Introducing micro clouds
Micro clouds are a new class of infrastructure for on-demand compute at the edge. Micro clouds are distributed, minimal and come in small to extremely large scale. In Ubuntu 20.10, Canonical introduces its micro cloud stack that combines MAAS, LXD, MicroK8s and Ceph on Ubuntu, to deliver resilient pocket clouds hardened for mission-critical workloads in 5G RANs, industry 4.0 factories, V2X infrastructures, smart cities and health care facilities.
On a Raspberry Pi, users can start with MicroK8s, to orchestrate highly available workloads at the edge or with LXD to build a home lab appliance using LXD’s clustering and virtual machine management capabilities. The Ubuntu 20.10 release introduces users a way to experiment, test, or develop with full cloud capabilities through the Raspberry Pi. With Ubuntu 20.10 on a Raspberry Pi, anything is possible, from robotics to AI/ML.
