Another great post by @patrickdebois titled “Devops – a Romance of Many Dimensions”. Patrick takes us through an old-world book Flatland: A Romance of Many Dimensions written by Edwin Abbott in 1884, and compares the rules of a two-dimensional world to our well known environments of operations and development. “Our field is continuously improving itself. The emergence of virtualization, cloud, nosql, configuration management, and infrastructure as code are all signs of technological improvements. I would catalog them under the term Agile Infrastructure.” is Debois’ interpretation of Flatland’s primary goal in life, children having more sides than their parents, consistently improving themselves in many ways.

Kief Morris (@kief), a continuous delivery enthusiast and American living in London tweeted the six reasons for ops to love devops. If you’ve missed it, here are his points:
- Reason #1 for ops to love #devops: Smaller releases means lower risk
- Reason #2 for ops to love #devops: Ops involved throughout development means fewer surprises at release time
- Reason #3 for ops to love #devops: Ops involved in dev means apps are well designed and tested for operational use
- Reason #4 for ops to love #devops: Ops involved in dev means infrastructure changes are planned and tested well ahead of release
- Reason #5 for ops to love #devops: Smaller releases mean far less work
- Reason #6 for ops to love #devops: Smaller releases mean problems are much simpler to find and fix, and less painful to roll back Read More
The folks at the Agile Web Operations blog added another couple of guest posts surrounding Devops.
The State of Devops
Written by James Turnbull, this post takes us back in a time machine to the days where the client-server was a passing fad and serious conversations where held in the car park. Jame’s summarized those conversations with three principles:
- Think before you act
- Change one thing at a time, not ten things at once
- If you fucked up then own up

Nolio has released version 3.0 of its Application Service Automation Platform (ASAP), with new measurement, audit and control features designed to elevate the product from automation tool to management suite. A new DevOps Manager exposes useful data to senior executives responsible for the application deployment process. With this dashboard, executives should be able to answer questions like: How long does it take to release an application, on average? How many deployments succeed? How many fail? How long does it take to perform a rollback? Which applications need the most remediation? Which users executed tasks in production? Which users touched a given application?

Day 5 – Why Aren’t You Doing Code Reviews?
Phil Hollenback writes about his ideas on the devops culture providing an overview of the tools used. “However, I do think there are a lot of good ideas to be found in the ‘devops culture’. One idea I particularly like is that sysadmins should think more like developers”

A nice Ben Rockwood (@benr) article on devops.
Let us first consider “devops”. It is a cultural movement which codifies various characteristics, including the zen like interweaving of development and operations, better integration of “IT” with the business objectives as a whole, infrastructure as code, agile (or lean depending on who you speak with) operations, etc, etc. Alright. As I’ve stated in the past, its all the things ITIL claimed to be but somehow more hip. Alright, capture that in your minds eye and then move it aside.

Application lifecycle management (ALM) vendor Serena Software has introduced a new strategy of orchestrated application delivery and is also automating release management to facilitate ‘devops’ – the pushing together of development and IT operations tasks and teams – for mainframe and distributed servers, including virtual and cloud computing environments.

DevOps aims to deal with the complexity of deploying and managing today’s modern applications.
DevOps is a grassroots movement that has grown over the last 12 months and brings together traditional silos in the IT department: developers, operators, system administrators, release managers, network engineers and others. Devops is very much an extension of the Agile movement, removing process bottlenecks and improving communication between the development and operations silos, resulting in applications being delivered better and faster and with less risk .
