Infrastructure Provisioning for Ansible with Digital Rebar Provision

Digital Rebar Provision (DRP) is the perfect technology partner for Ansible customers looking to automate their infrastructure setup before applying their orchestration tool of choice. DRP automatically generates a complete inventory of provisioned infrastructure which is a must have for Ansible to complete its orchestration. In addition, DRP is able to deploy Kubernetes clusters using Ansible and Kubespray as part of its standard Workflow automated process.

Together, DRP and Ansible enhance the automation, repeatability, and transparency for DevOps teams.

Learn more about DRP and Ansible in the demonstration video and podcasts below.

Week in Review: Automation and L8istSh9y Podcast Makes DZone

Welcome to the RackN and Digital Rebar Weekly Review. You will find the latest news related to Edge, DevOps, SRE and other relevant topics.

RackN Solutions – Automation

Automation is not simply taking manual tasks and replacing them with a machine. Rather, it is a methodology to assemble hardware and software infrastructure in a reliable, repeatable way saving time and effort. Automation also provides IT teams with the capability to rapidly meet new business challenges, learn new technologies, and reduce fire drills rather than spending significant cycles manually pushing buttons.

Week in Review: Data Center 2020 Blog Series from IBM Think 2018

Welcome to the RackN and Digital Rebar Weekly Review. You will find the latest news related to Edge, DevOps, SRE and other relevant topics.

Data Center of 2020 Blog Series from IBM Think 2018
(Series by Rob Hirschfeld, CEO/Co-Founder, RackN)

When discussing the data center of the future, it’s critical that we start by breaking the concept of the data center as a physical site with guarded walls, raised floors, neat rows of servers and crash cart pushing operators. The Data Center of 2020 (DC2020) is a distributed infrastructure comprised of many data centers, cloud services and connected devices.

The primary design concept of DC2020 is integrated automation not actual infrastructures.

RackN Portal Management Connection for the 10 Minute Demo

In my previous blog, I provided step by step directions to install Digital Rebar Provision on a new endpoint and create a new node using Packet.net for users without a local hardware setup. (Demo Tool on GitHub) In this blog, I will introduce the RackN Portal and connect it to the active setup running on Packet.net at the end of the demo process.

DC2020: Is Exposing Bare Metal Practical or Dangerous?

One of IBM’s major announcements at Think 2018 was Managed Kubernetes on Bare Metal. This new offering combines elements of their existing offerings to expose some additional security, attestation and performance isolation. Bare metal has been a hot topic for cloud service providers recently with AWS adding it to their platform and Oracle using it as their primary IaaS. With these offerings as a backdrop, let’s explore the role of bare metal in the 2020 Data Center (DC2020).

Physical servers (aka bare metal) are the core building block for any data center; however, they are often abstracted out of sight by a virtualization layer such as VMware, KVM, HyperV or many others. These platforms are useful for many reasons. In this post, we’re focused on the fact that they provide a control API for infrastructure that makes it possible to manage compute, storage and network requests. Yet the abstraction comes at a price in cost, complexity and performance.

The historical lack of good API control has made bare metal less attractive, but that is changing quickly due to two forces.

These two forces are Container Platforms and Bare Metal as a Service or BMaaS (disclosure: RackN offers a private BMaaS platform called Digital Rebar). Container Platforms such as Kubernetes provide an application service abstraction level for data center consumers that eliminates the need for users to worry about traditional infrastructure concerns.  That means that most users no longer rely on APIs for compute, network or storage allowing the platform to handle those issues. On the other side, BMaaS VM infrastructure level APIs for the actual physical layer of the data center allow users who care about compute, network or storage the ability to work without VMs.  

The combination of containers and bare metal APIs has the potential to squeeze virtualization into a limited role.

The IBM bare metal Kubernetes announcement illustrates both of these forces working together.  Users of the managed Kubernetes service are working through the container abstraction interface and really don’t worry about the infrastructure; however, IBM is able to leverage their internal bare metal APIs to offer enhanced features to those users without changing the service offering.  These benefits include security (IBM White Paper on Security), isolation, performance and (eventually) access to metal features like GPUs. While the IBM offering still includes VMs as an option, it is easy to anticipate that becoming less attractive for all but smaller clusters.

The impact for DC2020 is that operators need to rethink how they rely on virtualization as a ubiquitous abstraction.  As more applications rely on container service abstractions the platforms will grow in size and virtualization will provide less value.  With the advent of better control of the bare metal infrastructure, operators have real options to get deep control without adding virtualization as a requirement.

Shifting to new platforms creates opportunities to streamline operations in DC2020.

Even with virtualization and containers, having better control of the bare metal is a critical addition to data center operations.  The ideal data center has automation and control APIs for every possible component from the metal up.

Industry News

Maybe we’re just too lazy to put in the work to become DevOps-minded, though, to the industry’s credit, the desire to “get DevOps” is real. Roughly 10 years after DevOps was coined as a thing, enterprises are madly scrambling to embrace it, as survey data uncovers. The problem is that too often we think it’s about hiring a few “DevOps engineers” and setting them free to… DevOp… or whatever.

Many industrial applications have been developed to utilize IoT devices and the data they produce.  They generally use cloud hosting, analytics and edge computing technology, often provided and connected via an IoT Platform – a set of tools and run-time systems hosted on the cloud that enable the development and deployment of a “complete IoT solution.”

With the advent of KubCon and CloudNativeCon in Austin, Texas, on Wednesday, assorted enterprise vendors have chosen this week to flog their latest devops-oriented wares, before the impending holiday torpor leaves IT folks too distracted, weary or inebriated to care.

Digital Rebar

RackN

Like other Gartner events, the Infrastructure and Operations (IO) show is all about enterprises maintaining systems.  There are plenty of hype chasing sessions, but the vibe is distinctly around working systems and practical implementations.  Think: sports coats not t-shirts.  In that way, it’s less breathless and wild-eyed than something like KubeCon (which is busy celebrating a bumper crop of 1.0 projects).  The very essence of this show is to project an aura of calm IT stewardship.

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.

Dec 14, 2017 1:30 PM CST

We are actively looking for feedback from customers and technologists before general availability of both RackN and the Terraform plug-in. It takes just a few minutes to get started and we offer direct engineering engagement on our community slack channel. Get started now by providing your email on our registration page so we can provide you all the necessary links.
