RedHat Goes Atomic
The Red Hat Summit kicked off in San Francisco on Tuesday, and continued today with a raft of announcements.
Red Hat launched a new fork of Red Hat Enterprise Linux (RHEL) with the title “Atomic Host”. The new version is stripped down to enable lightweight deployment of software containers. Although the mainline edition also support software containers, this lightweight version improves portability.
This is part of a wider Red Hat initiative, Project Atomic, which also sees virtualisation platform Docker updated as part of the ongoing partnership between the two organisations.
Red Hat also announced a release candidate (RC) for Red Hat Enterprise Linux 7. The beta version has already been downloaded 10,000 times. The Atomic Host fork is included in the RC.
Topping all that is the news that Red Hat’s latest stable release, RHEL 6.5 has been deployed at the Organisation for European Nuclear Research – better known as CERN.
The European laboratory, which houses the Large Hadron Collider (LHC) and was birthplace of the World Wide Web has rolled out the latest versions of Red Hat Enterprise Linux, Red Hat Enterprise Virtualisation and Red Hat Technical Account Management. Although Red Hat has a long history with CERN, this has been a major rollout for the facility.
The logging server of the LHC is one of the areas covered by the rollout, as are the financial and human resources databases.
The infrastructure comprises a series of dual socket servers, virtualised on Dell Poweredge M610 servers with up to 256GB RAM per server and full redundancy to prevent the loss of mission critical data.
Niko Neufeld, deputy project leader at the Large Hadron Collider, said, “Our LHCb experiment requires a powerful, very reliable and highly available IT environment for controlling and monitoring our 70 million CHF detectors. Red Hat Enterprise Virtualization is at the core of our virtualized infrastructure and complies with our stringent requirements.”
Other news from the conference includes the launch of Openshift Marketplace, allowing customers to try solutions for cloud applications, and the release of Red Hat Jboss Fuse 6.1 and Red Hat Jboss A-MQ 6.1, which are standards based integration and messaging products designed to manage everything from cloud computing to the Internet of Things.
Ubuntu Cross-Platform Delayed
Ubuntu will not offer cross-platform apps as soon as it had hoped.
Canonical had raised hopes that its plan for Ubuntu to span PCs and mobile devices would be realised with the upcoming Ubuntu 14.04 release, providing a write-once, run-on-many template similar to that planned by Google for its Chrome OS and Android app convergence.
This is already possible on paper and the infrastructure is in place on smartphone and tablet versions of Ubuntu through its new Unity 8 user interface.
However, Canonical has decided to postpone the rollout of Unity 8 for desktop machines, citing security concerns, and it will now not appear along with the Mir display server this coming autumn.
This will apply only to apps in the Ubuntu store, and in the true spirit of open source, anyone choosing to step outside that ecosystem will be able to test the converged Ubuntu before then.
Ubuntu community manager Jono Bacon told Ars Technica, “We don’t plan on shipping apps in the new converged store on the desktop until Unity 8 and Mir lands.
“The reason is that we use app insulation to (a) run apps securely and (b) not require manual reviews (so we can speed up the time to get apps in the store). With our plan to move to Mir, our app insulation doesn’t currently insulate against X apps sniffing events in other X apps. As such, while Ubuntu SDK apps in click packages will run on today’s Unity 7 desktop, we don’t want to make them readily available to users until we ship Mir and have this final security consideration in place.
“Now, if a core-dev or motu wants to manually review an Ubuntu SDK app and ship it in the normal main/universe archives, the security concern is then taken care of with a manual review, but we are not recommending this workflow due to the strain of manual reviews.”
As well as the aforementioned security issues, there are still concerns that cross-platform apps don’t look quite as good on the desktop as native desktop versions and the intervening six months will be used to polish the user experience.
Getting the holistic experience right is essential for Ubuntu in order to attract OEMs to the converged operating system. Attempts to crowdfund its own Ubuntu handset fell short of its ambitious $20m target, despite raising $10.2 million, the single largest crowdfunding total to date.
Red Hat Releases Linux E-Beta
Red Hat has made available a beta of Red Hat Enterprise Linux 7 (RHEL 7) for testers, just weeks after the final release of RHEL 6.5 to customers.
RHEL 7 is aimed at meeting the requirements of future applications as well as delivering scalability and performance to power cloud infrastructure and enterprise data centers.
Available to download now, the RHEL 7 beta introduces a number of enhancements, including better support for Linux Containers, in-place upgrades, XFS as the default file system, improved networking support and improved compatibility with Windows networks.
Inviting customers, partners, and members of the public to download the RHEL 7 beta and provide feedback, Red Hat is promoting the upcoming version as its most ambitious release to date. The code is based on Red Hat’s community developed Fedora 19 distribution of Linux and the upstream Linux 3.10 kernel, the firm said.
“Red Hat Enterprise Linux 7 is designed to provide the underpinning for future application architectures while delivering the flexibility, scalability, and performance needed to deploy across bare metal, virtual machines, and cloud infrastructure,” Senior Product Marketing Manager Kimberly Craven wrote on the Red Hat Enterprise Linux blog.
These improvements address a number of key areas, including virtualisation, management and interoperability.
Linux Containers, for example, was partially supported in RHEL 6.5, but this release enables applications to be created and deployed using Linux Container technology, such as the Docker tool. Containers offers operating system level virtualisation, which provides isolation between applications without the overhead of virtualising the entire server.
Red Hat said it is now supporting an in-place upgrade feature for common server deployment types. This will allow customers to migrate existing RHEL 6.5 systems to RHEL 7 without downtime.
RHEL 7 also makes the switch to XFS as its default file system, supporting file configurations up to 500TB, while ext4 file systems are now supported up to 50TB in size and B-tree file system (btrfs) implementations are available for users to test.
Interoperability with Windows has also been improved, with Red Hat now including the ability to bridge Windows and Linux infrastructure by integrating RHEL 7 and Samba 4.1 with Microsoft Active Directory domains. Red Hat Enterprise Linux Identity Management can also be deployed in a parallel trust zone alongside Active Directory, the firm said.
On the networking side, RHEL 7 provides support for 40Gbps Ethernet, along with improved channel bonding, TCP performance improvements and low latency socket poll support.
Other enhancements include support for very large scale storage configurations, including enterprise storage arrays, and uniform management tools for networking, storage, file systems, identities and security using the OpenLMI framework.
