Welcome to the weekly post of the RackN blog recap of all things Digital Rebar, RackN, Edge Computing, and DevOps. If you have any ideas for this recap or would like to include content please contact us at info@rackn.com or tweet RackN (@rackngo) Items of the Week Industry News It’s a decade since DevOps became a “thing” – and people still don’t know what it means : The Register Maybe we're just too lazy to put in the work to become...

Join this webinar to learn more about the RackN Kubernetes installation integration using community tools like Kubeadm demonstrated at this week's KubeCon event (Slides) in Austin, TX. Co-Founders Rob Hirschfeld and Greg Althaus of RackN will discuss this fast and simple approach to operating Kubernetes. Of course, we’ll also demonstrate the technology installing Kubernetes following the immutable infrastructure model highlighting the automated provisioning technology built on the open source Digital Rebar project. After this webinar, you’ll be prepared...

            The RackN and Digital Rebar team are finalizing plans for next week's KubeCon + CloudNativeCon in Austin, TX from Dec 6 - 8, 2017. Rob Hirschfeld is hosting 2 sessions and we are having a booth in the sponsor showcase. All the info you need is below and we look forward to seeing you in Austin.

                    In this week’s L8ist Sh9y podcast Krishnan Subramanian, Founder and Chief Research Advisor of Rishidot Research talks about Edge Computing, the Kubernetes Ecosystem and the Composable Enterprise. Key highlights: “Multi-Cloud is the foundation of Modern Enterprise” – Krishnan Kubernetes ecosystem and the possibility that Serverless could replace it IT innovation requires a composable and layered approach, without this approach IT will find themselves trapped in a hard-wired infrastructure unable to move forward Topic                                 Time (Minutes.Seconds) Introduction     ...

The RackN team is proud of saying that we left the Orchestration out when we migrated from Digital Rebar v2 to v3. That would mean more if anyone actually agreed on what orchestration means… In this our case, I think we can be pretty specific: Digital Rebar v3 does not manage work across multiple nodes. At this point, we’re emphatic about it because cross machine actions add a lot of complexity and require application awareness that...

OpenStack is a real platform doing real work for real users.  So why does OpenStack have a reputation for not working?  It falls into the lack of core-focus paradox: being too much to too many undermines your ability to do something well.  In this case, we keep conflating the community and the code. I have a long history with the project but have been pretty much outside of it (yay, Kubernetes!) for the last 18 months.  That...

This talk was given on November 8 at the OpenStack Summit Sydney event. Abstract Kubespray (formerly Kargo) - is a project under Kubernetes community umbrella. From the technical side, it is a set of tools, that bring the possibility to deploy production-ready Kubernetes cluster easily. Kubespray supports multiple Linux distributions to host the Kubernetes clusters (including Ubuntu, Debian, CentOS/RHEL and Container Linux by CoreOS), multiple cloud providers to be used as an underlay for the cluster deployment (AWS, DigitalOcean,...

The difficulty in fully automating physical infrastructure environments, especially for distributed edge, adds significant cost, complexity and delay when building IT infrastructure. We’ve called this “underlay” or “ready state” in the past but “last mile” may be just as apt. The simple fact is that underlay is the foundation for everything you build above it so mistakes there are amplified. Historically, simple systems still required manual or custom steps while complex systems where fragile and hard to...

I love great conversations about technology – especially ones where the answer is not very neatly settled into winners and losers (which is ALL of them in IT).  I’m excited that RackN has (re)launched the L8ist Sh9y (aka Latest Shiny) podcast around this exact theme. Please check out the deep and thoughtful discussion I just had with Mark Thiele (notes) of Apcera where we covered Mark’s thought on why public cloud will be under 20% of IT and culture issues head on. Spoiler: we...
