Why Docker, Containers and systemd Drive a Wedge Through the Concept of Linux Distributions

Filed under

Web

The announcement of Rocket by CoreOS was perceived by many to be a direct challenge to Docker, particularly as it came on the eve of DockerCon Europe and threatened to overshadow news coming out at the event. Docker, Inc. CEO Ben Golub was quick to fire back with his ‘initial thoughts on the Rocket announcement’. This piece isn’t about the politics of ecosystems and VC funded startups, which I’ll leave to Colin Humphreys (and note an excellent response from Docker Founder and CTO Solomon Hykes). It also isn’t about managing open source community, which I’ll leave to Matt Asay. Here I want to look at systemd, which lies at the heart of the technical arguments.

What is Ubuntu Snappy?

Filed under

Ubuntu

If you're anything like me, you've probably heard about this new thing from Canonical called "Snappy" Ubuntu Core, but at the same time trying to understand exactly what it is may leave you cross-eyed, especially with the buzzwords such as "cloud", "containers" and "apps" floating about. Once you get a handle on it, it's obvious that Canonical's new baby isn't terribly useful for those of us who are simply users, but perhaps it provides an interesting preview of what could come to the desktop version of Ubuntu in the future.

Docker CTO Solomon Hykes to Devs: Have It Your Way

Interviews

"We made a very conscious effort with Docker to insert the technology into an existing toolbox. We did not want to turn the developer's world upside down on the first day. ... We showed them incremental improvements so that over time the developers discovered more things they could do with Docker. So the developers could transition into the new architecture using the new tools at their own pace."

Nebula, which bills itself as an enterprise private cloud company and is focused on OpenStack, is not exactly just another player in the OpenStack ecosystem. The company is funded by noted backers Kleiner Perkins Caufield & Byers, Comcast Ventures, but even more notably, the company was founded by Chris Kemp, who helped launch OpenStack back when he was NASA's CTO.

Linux container technology is experiencing tremendous momentum in 2014. The ability to create multiple lightweight, self-contained execution environments on the same Linux host simplifies application deployment and management. By improving collaboration between developers and system administrators, container technology encourages a DevOps culture of continuous deployment and hyperscale, which is essential to meet current user demands for mobility, application availability, and performance.

Earlier this month, a report by the Linux Foundation identified that Linux deployments are up 14 percent over the last three years, while Windows is down 9 percent. In addition, Linux solutions have grown 23 percent since 2013. What this further confirmed is that our strategy for IBM Power Systems growth is aligned with market realities: that Linux continues to grow in both the cloud and in enterprise application deployments – and more and more enterprises are turning to the value of Linux.

Mesosphere, a startup that provides commercial support for the Apache Mesos cluster management system, has debuted a "data center operating system."

Mesosphere DCOS uses the Mesos project to gang together machines running Linux, whether hosted in any number of clouds (Amazon, Google, Microsoft) or running on nearly any kind of infrastructure (bare metal, OpenStack, VMware).

Widely deployed at scale by companies like Twitter and Airbnb, Mesos has a proven track record. However, Mesosphere DCOS is designed to manage not only the applications but also the systems they run on.

Review: Peppermint OS 9

While I have to admit that I am not the target audience for a distribution focused on web-based applications, I found Peppermint 9 to be a solid distribution. Despite pulling components from multiple desktop environments, Peppermint 9's desktop is well integrated and easy to use. It was also easy to add both web-based and traditional applications to the system, so the distribution can be adjusted for users who prefer either. Peppermint 9 is not for everyone, but users who do most their work in Google Docs or Microsoft Office Online should give Peppermint a try. However, users accustomed to using traditional desktop applications might want to stick to one of the many alternatives out there. Yes, Peppermint 9 can be easily adjusted to use traditional desktop applications, but many of the other distribution options out there come with those kinds of applications pre-installed. Read more

A Major GNOME Icon Redesign is Getting Underway

Your favourite GNOME applications will soon have dramatically different icons. GNOME devs are redesigning the default icons for all GNOME core apps as part a wider overhaul of GNOME design guidelines. The move hope to make it easier (and less effort) for app developers to provide high-quality and useful icons for their software on the GNOME desktop. Not that this redesign is much a surprise, as the Adwaita folder icons we highlighted a few weeks back suggested a new tack was being taken on design. With the GNOME desktop environment shipping on the Purism Librem 5 smartphone, the timing of this revamp couldn’t be better. Read more
