It also includes support for Intel Cherryview, Haswell, Broadwell, and Merrifield systems, and initial support for Nvidia GK20A and GK110B GPU’s.
In addition to a very significant number of bug fixes, we see new architecture support for POWER8 and ARM64 platforms. While we’re on the kernel side, 14.10 includes the 3.16 kernel, and brings a whole host of striking new features that are worth spending some time on. In other words, it brings the best of both worlds in terms of the ability to keep your old, rotating disks, but enhance them with the speed of SSD. It allows one or more fast disk drives such as SSD to act as a cache for a conventional disk. As someone who often runs I/O intensive workloads, I often run into the eternal conundrum: how much SSD can I afford, and what’s the right balance between SSD and rotating disks to provide an acceptable compromise on speed while not breaking the bank? Bcache, a Linux kernel block layer cache, promises to solve this problem. My personal favourite feature however, is bcache. This used to create lots of problems in terms of security and separation of privileges. This allows any user to create system-wide container without the need for superuser privileges. 14.10 includes the latest LXC, the fastest, most secure bare-metal container to date, and Ubuntu now offers user-level container support. Ubuntu has always been a leader in container technology, and we intend to continue on that track. In addition, this release contains the latest release of Docker, v1.2. Without it, there is a very high overhead to find where an instance is in a cloud – you practically have to ping one instance from another one, a painfully slow process that this feature solves.Īll of the above are new features that really strengthen Ubuntu’s position as the number one scale-out platform for server and cloud. vxlan brings a scalable and performant tenant overlay networking option, and layer 2 population brings network traffic optimisation for multicast and broadcast traffic flow. separating internal network traffic for databases or messaging from public network access for end users.Ĭells are an interesting addition to Nova, and now the OpenStack charms support the scaling of a cloud using Nova Cells, allowing federation of database, messaging and compute resources within a single OpenStack cloud. Network Config support in the OpenStack charms separates traffic flows between OpenStack components into different networks, improving separation and reducing contention between traffic types, e.g. Much of this is reflected in Ubuntu, as we now have IPv6 support in the OpenStack charms, Juju and MAAS, and horizontally scalable neutron gateway for software-defined networking in OpenStack.

Check the Juno release notes for a full listing of features. Juno brings a number of valuable improvements, especially on the networking side with Neutron IPv6 support for tenant networks, and Neutron Distributed Virtual Router for optimised east-west traffic routing and highly available north-south routing. This release includes the Juno release of OpenStack, which will be supported on 14.10 for nine months, and on 14.04 for 18 months. Make sure to visit our booth at the OpenStack Summit in Paris to check out some of these solutions yourself.
Our Charm Partner Programme is well underway and we expect to see the first fruits of it in the very near future, creating a large and strong ecosystem around Juju. You will hear us talk a lot about these in the coming weeks and months, as we seek to include more and more workloads into Juju.
In this cycle, we introduce Cloud Foundry, as well as a number of big data solutions including ElasticSearch, and several Hadoop solutions, including Hive, data analytics using SQL-like or Pig Latin, and real-time analytics using Storm. A beta version of some of the most complex workloads, deployed in minutes via Juju. However, this release is packed full of new features for Ubuntu Server, OpenStack, as well as our cloud tools Juju and MAAS.īefore going into specific features, I will start with the pièce de résistance: a true demonstration of the power of Juju. As always, we recommend that enterprise customers stay on the latest LTS release, in this case 14.04. Today we release Ubuntu 14.10, aka ‘Utopic Unicorn’, for cloud and servers.
