Kubernetes Snaps: The Quick Version
When we built the Canonical Distribution of Kubernetes (CDK), one of our goals was to provide snap packages for the various Kubernetes clients and services: kubectl, kube-apiserver, kubelet, etc.
While we mainly built the snaps for use in CDK, they are freely available to use for other purposes as well. Let’s have a quick look at how to install and configure the Kubernetes snaps directly.

Kubernetes is Transforming Operations in the Enterprise
At many organizations, managing containerized applications at scale is the order of the day (or soon will be). And few open source projects are having the impact in this arena that Kubernetes is.
Above all, Kubernetes is ushering in “operations transformation” and helping organizations make the transition to cloud-native computing, says Craig McLuckie co-founder and CEO of Heptio and a co-founder of Kubernetes at Google, in a recent free webinar, ‘Getting to Know Kubernetes.’ Kubernetes was created at Google, which donated the open source project to the Cloud Native Computing Foundation.

Kubernetes gains momentum as big-name vendors flock to Cloud Native Computing Foundation
Like a train gaining speed as it leaves the station, the Cloud Native Computing Foundation is quickly gathering momentum, attracting some of the biggest names in tech. In the last month and a half alone AWS, Oracle, Microsoft, VMware and Pivotal have all joined.
It’s not every day you see this group of companies agree on anything, but as Kubernetes has developed into an essential industry tool, each of these companies sees it as a necessity to join the CNCF and support its mission. This is partly driven by customer demand and partly by the desire to simply have a say in how Kubernetes and other related cloud-native technologies are developed.

The Cloud-Native Architecture: One Stack, Many Options
As the chief technology officer of a company specialized in cloud native storage, I have a first hand view of the massive transformation happening right now in enterprise IT. In short, two things are happening in parallel right now that make it radically simpler to build, deploy and run sophisticated applications.
The first is the move to the cloud. This topic has been discussed so much that I won’t try to add anything new. We all know it’s happening, and we all know that its impact is huge.

Sysadmin 101: Leveling Up
I hope this description of levels in systems administration has been helpful as you plan your own career. When it comes to gaining experience, nothing quite beats making your own mistakes and having to recover from them yourself. At the same time, it sure is a lot easier to invite battle-hardened senior sysadmins to beers and learn from their war stories. I hope this series in Sysadmin 101 fundamentals has been helpful for those of you new to the sysadmin trenches, and also I hope it helps save you from having to learn from your own mistakes as you move forward in your career.

Samsung, Red Hat to Work on Linux Drivers for Future TechThe metaverse is expected to uproot system design as we know it, and Samsung is one of many hardware vendors re-imagining data center infrastructure in preparation for a parallel 3D world. Samsung is working on new memory technologies that provide faster bandwidth inside hardware for data to travel between CPUs, storage and other computing resources. The company also announced it was partnering with Red Hat to ensure these technologies have Linux compatibility. |
