Maven doesn’t like it when you use different verison numbers to the Maven standard format. I’m not “Maven bashing”, it’s just that this particular problem doesn’t have quite the elegant solution I was looking for. I do appreciate Maven, honestly.

The general best practice is to add an additional element for each service tier, also know as N+1 redundancy. This approach is straight forward, but many people would actually be surprised by how often these schemes fail.

I’m using Cobbler and Puppet to automate the creation of VMs on my laptop for testing/staging purposes so I thought I’d blog about it here. The aim is to use Cobbler to setup the base operating system and install puppet, then let Puppet take over and install and configure the rest of the system.

When the term NoOps was coined by Forrester last April it stirred up a lot of controversy online, especially in the DevOps camp. The discussion has been ongoing since then with no resolution. What I’m gonna argue is that except for the random troll, everybody is working toward the same goal and the problem is terminology.

A development team’s infrastructure - development and QA environments, CI servers, SCM servers, etc. - are indisputably business critical, but rarely given the kind of monitoring attention that production environments are. This is a missed opportunity, not only to ensure the continuity of development work, but also to gain valuable insight.

It's a simple feature, but it can save a bunch of time. You could also setup a handler set specifically for metrics and another set for notifications. In the case of metrics, you could easily ship metrics to multiple systems – Graphite, Librato, Cube, etc. And adding a new system would be as simple as creating the handler and adding it to the handler set.

It must have been at least five years ago, when Puppet was getting popular, that the author first ran into someone terrified of losing his job because of automation. However, what also history suggests is that resourceful and competent engineers will always have a job.

Automated management of infrastructure is vital for delivering highly effective IT services. But although there are plenty of tools available to help implement automation, it’s still common to see operations teams manually installing and managing their servers, which leads to a high-maintenance infrastructure, which soaks up the team’s time on firefighting and other reactive tasks. Here are some recommendations...
