Packed with stability and performance for both public and private clouds, OpenStack Ussuri brings great improvements to the OVN (Open Virtual Networking) driver, which is now stable and provides a fully functional open source SDN solution. The Masakari project, which lets you run highly available workloads on the top of OpenStack, also received some improvements and it can now allow tenants to more easily meet their availability goals when deploying workloads without using complex technologies like Corosync or Pacemaker.
