Welcome to the age of containerization, where an ecosystem led by startup Docker is leading IT organizations to ineffable peaks of efficiency, helping them scale their workloads ever-higher, and probably baking them a nice cake to boot (it's my birthday, I have cake on the brain, sue me). Microsoft, Google and Amazon Web Services are all tripping over themselves to make sure prospective customers know that their clouds are the place to be if you want to get the most from Docker.
The stage is set for SDN (software-defined networking) to change the way we push data through our infrastructures, with the promises of more agile network provisioning and management, as well as more affordable network hardware. But for many, the SDN concept is still amorphous. What does SDN look like in practice?
To shed light on this question, I sat down with a few Dell Networking S6000 switches running Cumulus Linux 2.3. There are many approaches to an SDN solution, but one of the most significant is the advent of white-box switches and à la carte switch firmware. This is the essence of the solution offered by Cumulus Networks.
Once more the best of the best supercomputer experts came together to decide which are the fastest of the fast computers. Number one with a bullet continues to be Tianhe-2, aka Milky Way-2, a Chinese supercomputer developed by China’s National University of Defense Technology. Its operating system? Linux of course.
When containers first appeared in Linux, the natural assumption was that it would be yet another of many technologies that Linux has assimilated.
But then came Docker, a novel use of containers to make apps portable and self-contained. It's set Linux vendors scrambling, both to to rethink the way containers are implemented in Linux and to see how Linux can be reworked around Docker's application-centric model.
Here's how four major enterprise Linux distributions are readying themselves for a Docker-ized future.
ownCloud uses its own server-to-server sharing capability to bypass all the Web interfaces that trip up seamless file sharing across silos.
Anybody who says there's nothing new under the sun--or clouds--ought to read this story.
Cloud storage and collaboration service provider ownCloud (yes, with a lower-case "o") has found a way to sync up files from all over the place--from the cloud, to enterprise silos, to personal connected storage devices, to other disparate places--and make them easily available and sharable using its own cloud (hence, ownCloud) common file access layer.
The 4MLinux developer is managing the size of his distributions down to the last bit and he's doing the same with the server edition. In fact, 4MLinux distros are well known for the fact that they are very small, regardless of their purpose. The Server edition follows the same cardinal rule and weighs just 192 MB, which is almost ridiculous.
Also, it's worth pointing out that 4MLinux Server Edition comes with a desktop environment, which is rather unusual. Most of the Linux server distros don't have any kind of desktop and it's not really required. On the other hand, it's nice to see that a developer is going the extra mile to provide a friendly and easy to use interface for his users.
Red Hat recognizes the changing face of enterprise computing involves containerization technology and to that end, they announced a Beta release of their Linux container platform called Red Hat Enterprise Linux Atomic Host.
Containerization is a new trend that offers a more efficient and faster way to deliver applications than virtual machine technology. In a sense, it’s another step in virtualization that takes the concept and strips it down even further to produce greater resource efficiencies and faster deployment.
