Podcast Guest: Ash Young,Chief Evangelist of Cachengo

Technology leader with over 20 years experience, primarily in storage. Created the first open source NAS (network attached storage) stack, the first unified block/file storage stack for Linux, the first storage management software, and the list goes on.

Since 2012, I have been heavily involved in NFV (Network Functions Virtualization). I wrote a bunch of the standards and was editor for the Compute/Storage Domain in the Infrastructure Working Group for NFV. And then I started up the open source effort to close the gaps for achieving our vision of the NFVI. This was the precursor to OPNFV.

The best way to understand what I do is to imagine being a high-level marketing exec who comes up with a whiz bang product and business idea, including business plan, competitive analysis, MRD, everything, but now comes the hand-off with your engineering organization, only to hear a litany of nos. Well, I got tired of being told “No, it can’t be done” or “No, we don’t know how to do it”, so I started doing it myself. I call this skill “Rapid Prototyping”, and over the years I have found it to be a very missing gap in the product development process. When Marketing comes up with ideas, we need a way to very efficiently validate the technology and business concepts before we commit to a lengthy engineering cycle.

I’m just one person, working in a company of over 180,000 people and in a very dynamic industry. My ability to get creative and to influence businesses is never a dull moment; and I will probably be 100 years old and still writing open source software.

Getting Edge-y at OpenStack Summit – 5 ways it’s an easy concept with hard delivery

Posted by Rob H in OpenStack, Technology

The 2018 Vancouver OpenStack Summit is very focused on IT infrastructure at the Edge. It’s a fitting topic considering the telcos’ embrace for the project; however, building the highly distributed, small footprint management needed for these environments is very different than OpenStack’s architectural priorities. There is a significant risk that the community’s bias towards it’s current code base (which still has work needed to service hyper-scale and enterprise data centers) will undermine progress in building suitable Edge IT solutions.

There are five significant ways that Edge is different than “traditional” datacenter.  We often discuss this on our L8istSh9y podcast and it’s time to summarize them in a blog post.

IT infrastructure at the Edge is different than “edge” in general. Edge is often used as a superset of Internet of Things (IoT), personal devices (phones) and other emerging smart devices. Our interest here is not the devices but the services that are the next hop back supporting data storage, processing, aggregation and sharing. To scale, these services need to move from homes to controlled environments in shared locations like 5G towers, POP and regional data centers.

Unlike built-to-purpose edge devices, the edge infrastructure will be built on generic commodity hardware.

Here are five key ways that managing IT infrastructure at the edge is distinct from anything we’ve built so far:

  • Highly Distributed – Even at hyper-scale, we’re used to building cloud platforms in terms of tens of data centers; however, edge infrastructure sites will number in the thousands and millions!  That’s distinct management sites, not servers or cores. Since the sites will not have homogeneous hardware specifications, the management of these sites requires zero-touch management that is vendor neutral, resilient and secure.  
  • Low Latency Applications – Latency is the reason why Edge needs to be highly distributed.  Edge applications like A/R, V/R, autonomous robotics and even voice controls interact with humans (and other apps) in ways that require microsecond response times.  This speed of light limitation means that we cannot rely on hyper-scale data centers to consolidate infrastructure; instead, we have to push that infrastructure into the latency range of the users and devices.
  • Decentralized Data – A lot of data comes from all of these interactive edge devices.  In our multi-vendor innovative market, data from each location could end up being sprayed all over the planet.  Shared edge infrastructure provides an opportunity to aggregate this data locally where it can be shared and (maybe?) controlled. This is a very hard technical and business problem to solve.  While it’s easy to inject blockchain as a possible solution, the actual requirements are still evolving.
  • Remote, In-Environment Infrastructure – To make matters even harder, the sites are not traditional raised floor data centers with 24×7 attendants: most will be small, remote and unstaffed sites that require a truck roll for services.  Imagine an IT shed at the base of a vacant lot cell tower behind rusted chain link fences guarded by angry squirrels and monitored by underfunded FCC regulators.
  • Multi-Tenant and Trusted – Edge infrastructure will be a multi-tenant environment because it’s simple economics driving as-a-Service style resource sharing. Unlike buy-on-credit-card public clouds, the participants in the edge will have deeper, trusted relationships with the service providers.  A high degree of trust is required because distributed application and data management must be coordinated between the Edge infrastructure manager and the application authors.  This level of integration requires a deeper trust and inspect than current public clouds require.

These are hard problems!  Solving them requires new thinking and tools that while cloud native in design, are not cloud tools.  We should not expect to lift-and-shift cloud patterns directly into edge because the requirements are fundamentally different.  This next wave of innovation requires building for an even more distributed and automated architecture.

I hope you’re as excited as we are about helping build infrastructure at the edge.  What do you think the challenges are? We’d like to hear from you!

RackN and Digital Rebar Philosophy of Provisioning

Posted by Rob H in Digital Rebar, Immutable, rackn

Re-defining physical automation to make it highly repeatable and widely consumable while also meeting the necessarily complex and evolving heterogeneous data center environment is the challenge the RackN team is solving. To meet this challenge, we have developed a unique philosophy in how we build our technology; both open source Digital Rebar and the additional RackN packages.

  • Stand-alone Provisioning
  • Building Software from the API
  • Single Golang Executable
  • Modular Components – Composable Content
  • Operator Defined Workflows
  • Immutable Infrastructure
  • Distributed or Consolidated Architectures

Stand-alone Provisioning

It is critical that Digital Rebar Provision (DRP) provides operators the maximum flexibility in terms of where to run the service (Server, Top-of-Rack Switch, ARM, Intel, etc) as well as removal of any dependencies that might restrict its deployment.  Each environment has it’s own unique Infrastructure DNA; the hardware, operating systems, and application stacks that drive the Infrastructure underlay.

Building Software from the API

The Digital Rebar Provision solution is built with an API first mentality.  Features and enhancements are implemented as an API (making it a first-class citizen), and the CLI is dynamically generated from the API which insures 100% coverage of API implementations within the CLI.  

This methodology also allows for the CLI to directly follow the structure and syntax of the API, making it easy for an Operator or Developer to understand and flexibly interchange the API and CLI syntax.  

At RackN we believe in strongly in the 12-Factor App methodology for designing modern software.  DRP is a direct reflection of these principles.

Single Golang Executable

DRP is built with Golang which is a modern Procedural language that is easily cross-compiled for multiple operating systems and processor architectures.  As a benefit, the DRP service and CLI tool (dr-provision and drpcli respectively) can run on platforms that range from small Raspberry Pi embedded systems, network switches at the Top-of-Rack, huge Hyper Converged Infrastructure (HCI) servers, to everything in between.  It is currently compiled and runs on Linux (arm, intel, 32 bit, and 64 bit), Mac OS X (64 bit), and Windows (64 bit).

The dr-provision binary is very small and lightweight, requiring almost zero external dependencies.  Current external dependencies are unzip, pk7zip, and bsdtar, and these dependencies should be removed in a future version.  At only 30 MByte in size, it requires fairly little resources to run.  

Modular Components ~ Composable Content

Modular architecture allows us to create complex solutions from a set of simple building blocks that offer functionality that is well tested. Breaking complex problems down in to small components, and then allowing strong templating capabilities creates a structure that allows for strong reuse patterns.   This approach permeates all of the “Content” components that create the foundational building blocks for composable provisioning activities.  

Operator Defined Workflows

Each environment has a unique set of services, applications, tooling, and practices for managing the Infrastructure.  Taking the concepts of Composable Content, we allow an operator or developer a flexible structure in which they have control in determining how loosely or tightly to integrate the DRP provisioning services in to their environment.  Every customer environment has a unique set of tools, and this methodology allows for smooth integration with those operational principles

Immutable Infrastructure    

Maintaining hardware and software in a massive data center or cloud is a significant challenge without the additional overhead of ensuring that patches are properly applied. Any changes to an active solution can introduce complications on a live system which is a major barrier to having security updates and other patches completed in a timely manner.

A better method is to only deploy a “golden image” to the live system and rather than patch each individual instance, simply tear down the instance and replace with a new copy of the “golden image.”  All patches can be applied and tested to create a new golden image which is easily rolled out in the create – destroy- re-create model of  immutability.

Distributed or Consolidated Architectures

Traditional data center and lab environments utilize centralized provisioning services.  While DRP has strong support for this scale-up or consolidated model, shifting patterns in application and service deployment topology dictates an evolving provisioning service solution.  Current Internet-of-Things (IoT), Edge, and Fog architectures distribute resources across disperse environments.

In the traditional model, a large scale operator might support a handful of datacenters with 10s of thousands of hosts in each facility.   These new trending architecture patterns can encompass 1000s of different locations, each hosting a few dozen to a few hundred hosts.  This shift creates significant burden on operational and infrastructure management tooling to support the complexities of these scale-out designs.

With strong multi-endpoint management tooling, the RackN portal can easily support both models for provisioning.  Long-lived scale-up environments with a service that is updated, upgraded, managed, loved, and cared for can exist seamlessly alongside environments with a create/destroy pattern that treats 1000s of provisioning endpoints as disposable assets.

Items of the Week

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.
