SRE Items of the Week

RackN Announcement
[PRESS RELEASE] RackN Ends DevOps Gridlock in Data Center  

Today we announced the availability of Digital Rebar Provision, the industry’s first cloud-native physical provisioning utility.  We’ve had this in the Digital Rebar community for a few weeks before offering support and response has been great! READ MORE

Cloud Native PHYSICAL PROVISIONING? Come on! Really?!
 By Rob Hirschfeld

Today, RackN announce very low entry level support for Digital Rebar Provisioning – the RESTful Cobbler PXE/DHCP replacement.  Having a company actually standing behind this core data center function with support is a big deal; however…

We’re making two BIG claims with Provision: breaking DevOps bottlenecks and cloud native physical provisioning.  We think both points are critical to SRE and Ops success because our current approaches are not keeping pace with developer productivity and hardware complexity. READ MORE

Slides from Rob Hirschfeld’s talk – The Server Cage Match

SRE vs DevOps vs Cloud Native: The Server Cage Match by Rob Hirschfeld

I don’t believe in DevOps shaming. Our community seems compelled to correct use of DevOps as an adjective for tools, teams and teapots. The frustration is reasonable: DevOps clearly taps into head space for both devs and operators who see a brighter automated future together. For example, check out this excellent DevOps discourse by Cindy Sridharan.

As an industry, we crave artificial conflict so it’s natural to try and distill site reliability engineering (SRE), DevOps and cloud native into warring factions when they are not. They all share a focus on Lean process. READ MORE

He looked at me briefly before he barked one word in reply — DevOps — and then promptly made a beeline for the pizza at the back of the room. READ MORE

An Influx of Kubernetes Installers Raises Questions Around Conformance

For the Kubecon Europe last month, industry observer Joseph Jacks pulled together a list of over SIXTY (yes, 60) Kubernetes installers and services. This wealth of variation that made itself known as the conference, happily, kicked off a conformance effort to ensure that users get a consistent experience. I’m a strong believer that clear conformance builds ecosystems and have deep experience working on that from my OpenStack DefCore efforts.

In short, conformance is not a vendor issue: it’s a user experience and ecosystem issue.  READ MORE
