Week in Review: RackN talks Immutability and DevOps at SRECon Americas

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

Immutable Deployments talk at SRECon Americas

Rob Hirschfeld presented at SRECon Americas this week, “Don’t Ever Change! Are Immutable Deployments Really Simpler, Faster and Safer?”

Configuration is fragile because we’re talking about mutating a system. Infrastructure as code, means building everything in place. Every one of our systems have to be configured and managed and that creates a dependency graph. We can lock things down, but we inevitably have to patch our systems.

Immutable infrastructure is another way of saying “pre-configured systems”. Traditional deployment models do configuration after deployment, but it’s better if we can do it beforehand. Immutability is a DevOps pattern. Shift configuration to the left of our pipeline; move it from the production to build stage.

Series Intro: A Focus on Sustaining Operations

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.

As an industry, we need to actively choose implementations that unify our operational models to create portability and eliminate silos. This means investing more in sustaining operations (aka Day 2 Ops) that ensure our IT systems can be constantly patched, updated and maintained. The pace of innovation (and discovered vulnerabilities!) requires that we build with the assumption of change. DC2020 cannot be “fire and forget” building that assumes occasional updates.

There are a lot of disruptive and exciting technologies entering the market. These create tremendous opportunities for improvement and faster innovation cycles. They also create significant risk for further fragmenting our IT operations landscape in ways to increase costs, decrease security and further churn our market.

It is possible to be for both rapid innovation and sustaining operations, but it requires a plan for building robust automation.

The focus on tightly integrated development and operations work is a common theme in both DevOps and Site/System Reliability Engineering topics that we cover all the time. They are not only practical, we believe they are essential requirements for building DC2020.

Over this week, I’m going to be using the backdrop of IBM Think to outline the concepts for DC2020. I’ll both pull in topics that I’m hearing there and revisit topics that we’ve been discussing on our blogs and L8ist Sh9y podcast. Ultimately, we’ll create a comprehensive document: for now, we invite you to share your thoughts about this content in it’s more raw narrative form. 

Week in Review : Test Digital Rebar in Minutes with Hosted Physical Infrastructure

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

Deploy and Test Digital Rebar Provision with No Infrastructure in 10 Minutes

For operators looking to better understand Digital Rebar Provision (DRP) RackN has developed an easy to follow process leveraging Packet.net for physical device creation. This process allows new users to create a physical DRP endpoint and then provision a new physical node on Packet. Information and code to run this guide is available at https://github.com/digitalrebar/provision/tree/master/examples/pkt-demo.

In this blog, I will take the reader through the process with images based on running via my Mac.

Site Reliability Engineering: 4 Things to Know

Organizations that have embraced DevOps and cloud-native architecture might also want to investigate SRE. Interop ITX expert Rob Hirschfeld explains why.

To find out more about site reliability engineering, Network Computing spoke with Rob Hirschfeld, who has been in the cloud and infrastructure space for nearly 15 years, including work with early ESX betas and serving on the Open Stack Foundation Board. Hirschfeld, cofounder and CEO of RackN, will present “DevOps vs SRE vs Cloud Native” at Interop ITX 2018.
