Author’s note: We’re looking for RackN Beta participants who want to help refine next generation deployment capabilities like the one described below.  We have these processes working today - our goal is to make them broadly reusable and standardized. We’ve been posting [Go CI/CD and Immutable Infrastructure for Edge Computing Management] and podcasting [Discoposse: The Death of Configuration Management, Immutable Deployment Challenges for DevOps] about the concept of immutable infrastructure because it offers simpler and more repeatable...

Operating hardware is too hard today. And too expensive.  Let’s fix that. The problem with physical ops is not that it’s hard, complex or fragile. Okay, it is and those ARE problems, but they are compounded by the lack of shared management software and practices missing from this layer.  When the RackN team set out to solve these physical challenges, we knew the software had to be very focused to replace the current Cobbler and Foreman environments....

Last week, I was able to attend the HashiConf 2017 event in my hometown of Austin, Texas.  HashiCorp has a significant following of loyal fans for their platforms and the show reflected their enthusiasm for the HashiCorp clean and functional design aesthetic.  I count the RackN team in that list - we embedded Consul deeply into Digital Rebar v2 and recently announced a cutting edge bare metal Terraform integration (demo video) with Digital Rebar Provision (v3). Overall,...

We’ve made open network provisioning radically simpler.  So simple, you can install in 5 minutes and be provisioning in under 30.  That’s a bold claim, but it’s also an essential deliverable for us to bridge the Ops execution gap in a way that does not disrupt your existing tool chains. We’ve got a remarkable list of feature additions between Digital Rebar Provision (DRP) v3.0 and v3.1 that take it from basic provision into a powerful distributed infrastructure...

TL;DR: We’ve built a buttery smooth Terraform provider for Bare Metal that runs equally on, of course, servers, Packet.net servers or VirtualBox VMs.  If you like Hashicorp Terraform and want it to own your data center too, then read on. Deep into the Digital Rebar Provision (DRP) release plan, a customer asked the RackN team to build a Terraform provider for DRP.  They had some very specific requirements that would stress all the new workflows and out-of-band...

In our last post, we pretty much tore apart the idea of running mini-clouds on the edge because they are not designed to be managed at scale in resource constrained environments without deep hardware automation.  While I’m a huge advocate of API-driven infrastructure, I don’t believe in a one-size-fits-all API because a good API provides purpose-driven abstractions. The logical extension is that having deep hardware automation means there’s no need for cloud (aka virtual infrastructure) APIs.  This...

I left the OpenStack OpenDev Edge Infrastructure conference with a lot of concerns relating to how to manage geographically distributed infrastructure at scale.  We’ve been asking similar questions at RackN as we work to build composable automation that can be shared and reused.  The critical need is to dramatically reduce site-specific customization in a way that still accommodates required variation - this is something we’ve made surprising advances on in Digital Rebar v3.1. These are very serious...

Last week, I attended a unique OpenDev Edge Infrastructure focused event hosted by the OpenStack Foundation to help RackN understand the challenges customers are facing at the infrastructure edges.  We are exploring how the new lightweight, remote API-driven Digital Rebar Provision can play a unique role in these resource and management constrained environments. I had also hoped the event part of the Foundation’s pivot towards being an “open infrastructure” community that we’ve seen emerging as the semiannual...

TL;DR: If you are containerizing your applications, you need to be aware of this "service mesh" architectural pattern to help manage your services. Gluecon turned out to be all about a microservice concept called a “service mesh” which was being promoted by Buoyant with Linkerd and IBM/Google/Lyft with Istio.  This class of services is a natural evolution of the rush to microservices and something that I’ve written microservice technical architecture on TheNewStack about in the past. A service...

Welcome to the weekly post of the RackN blog recap of all things SRE. If you have any ideas for this recap or would like to include content please contact us at info@rackn.com or tweet Rob (@zehicle) or RackN (@rackngo) SRE Items of the Week RackN and our Co-Founder and CEO Rob Hirschfeld openly called for a significant change to the OpenStack and Kubernetes communities in his VMBlog.com post, How is OpenStack so dead AND yet so very...
