Canonical on Wednesday announced the general availability of OpenStack Ussuri on Ubuntu 20.04 LTS and Ubuntu 18.04 LTS.
The most notable enhancements of the new OpenStack upstream release are stabilisation efforts around the Open Virtual Networking (OVN) driver and the Masakari project which allow organisations to run highly available workloads on the top of an open source software-defined networking (SDN) platform. Full commercial support for OpenStack Ussuri in Canonical’s Charmed OpenStack distribution will come with the OpenStack Charms 20.05 release on May 20th.
The latest upstream changes around the OVN driver have opened doors to stabilising it as the future default driver. This is due to the OVN driver being merged into the Neutron repository and becoming one of the in-tree Neutron modular layer 2 (ML2) drivers. Compared to the traditional Open vSwitch (OVS) driver, OVN provides support for virtual network abstraction and better segregation of the control from the data plane, resulting in a fully functional open source SDN solution.

The OpenStack Ussuri release brings an unprecedented level of stability and performance for public and private clouds that need to deliver VMs, containers and bare metal instances.
TYtus Kurek, Product Manager, Canonical
OpenStack Ussuri on Ubuntu 20.04 LTS brings five years of commercial support and ten years of security updates out of the box, making it an ideal candidate for production OpenStack deployments while introducing major improvements to projects such as OVN and Masakari.
