Why the year of ‘NoOps’ will never come

A PaaS is a wonderful thing that is giving an opportunity to ideas that would probably not otherwise see the light of the internet, and while it drastically reduces the need for IT staff to almost zero it still represents a small share of the tech world and that percentage won’t change any time soon, certainly not in 2013, because of market needs.

Continuous Delivery Using Maven

I’m a big fan of Ant, I’d usually choose it (or probably Gradle now) over Maven any day of the week, but there was already an existing Ant build system in place, which had grown a bit monolithic (that’s my polite way of saying it was a huge mess), so I didn’t want to go there! And besides, the first project that would be going into the new continuous delivery system was a simple Java project – way too straightforward to justify rewriting the whole ant system from scratch and improving it, so I went for Maven.

Getting out of the Developers' Way – Monitoring

The traditional model is to have Ops ask Dev what metrics they need monitored & to set those up. But this is a bad practice because this often means that monitoring can’t start until the metrics are available in the code, which can take days or weeks.

Puppet vs. Chef – The Devops Deathmatch

I’ve been using Puppet to mange systems for the last four years (at least!) however a new contract has meant I’ve needed to learn Chef. A few months ago I was looking for a blog post on the differences between puppet and Chef written from an objective point of view and the fantastic @nathenharvey produced a blog post about exactly that topic. This post is more of a comment on my feelings about the two different systems and comparing the way in which they work.
