Ubuntu 15.04 available for download
Ubuntu 15.04 is available for download from Canonical, and comes with updates across the desktop, phone, cloud and IoT ecosystem. The latest release features a fully converged platform spanning the cloud, device and client.
This version of Ubuntu comes with products such as the Dell XPS 13 Developer Edition. It brings a host of improvements and enhancements designed to help cloud-focused businesses and developers design, deploy and manage successful cloud projects. It not only introduces new tools for cloud and IoT development, but also makes the desktop more productive with integrated menus and dashboard usability improvements.
With the new Ubuntu OpenStack Kilo, enterprises and telecom companies can experiment a great deal more with OpenStack. And Neutron has been updated to include Distributed Virtual Routing (DVR) to enable the former to scale more efficiently using multiple nodes. Ubuntu OpenStack also includes a new OpenStack nova driver for LXD—nova-compute-LXD, which allows end users to deploy workloads on OpenStack into containers, based on LXD. The advantages are high performance and density compared to KVM based workloads.
Support for ZeroMQ (0MQ) is also included with Ubuntu OpenStack via the Oslo messaging systems. 0MQ is a high-performance, asynchronous messaging library that does not require the use of a dedicated message broker. The aim of using 0MQ is to cut down messaging bottlenecks created at the messaging brokers in large scale deployments. The large organisations and service providers that Canonical works with require the highest levels of scalability, efficiency and flexibility from OpenStack.
As the Ubuntu 15.04 container features live migration of LXC containers between hosts, an improved security model for containers through AppArmor profiles and Docker updated to 1.5, developers run LXD on all the machines where they want to create and tear down container based workloads in this new Ubuntu container environment.
In Ubuntu OpenStack, the reference implementation of Cinder is based on Ceph where important updates have been made. It comes with the new version of Ceph Hammer ensuring a better performance via SSD. It also features improved performance of spinning disks via a front end SSD based cache. ‘Snappy’ which is expected to evolve in the coming years, is available in Ubuntu 15.04 for the first time. With Systemd as the default init system, Ubuntu 15.04 is available for download at www.ubuntu.com/download.
