Exploring EC2 pricing data using R

Replacing Packer With KitchenCI and a Rakefile

An introduction to creating validated AMIs without using Packer.

Don't get me wrong, I love the HashiCorp products. I've been a Vagrant user since way back in my BC (Before Cloud) days and have continued a strong run of success backing the HashiCorp team.

DevOps, Deindividuation and the DeLorean.

Trent Hornibrook theorises that the "us"/"them" culture in some organisations is a symptom of the social psychology concept 'Deindividuation'.

Encourage direct communication between people at all levels. Avoid, at all cost, the feedback by organisational hierarchy. Communication loses its authenticity when performed this way.

The Four values of a devops transformation

A look into the four values that support a successful devops transformation.

Just like the agile transformations of the past, there is a difference between ‘Doing Agile’, and ‘Being Agile’. ‘We do standups’ - therefore we are Agile. With the increase in adoption of devops practices, are we ‘Doing devops’ or are we ‘Being devops’?
