It's been really interesting to watch the dramatic uptick in activity around the automation space the last year or two. I don't need to go into too much detail on the benefits that automation offers here; consistency and scalability are two of the more prominent that come to mind. What has struck me, though, is that it feels like the way that companies are going about it is missing a key step.
OK, so I probably just closed out 100 games of Bulls**t Bingo in the title of this blog post but I'll stand by it. You want actual agility in what you do? You need a safety net. That safety net is automated testing.
You've used Chef/Puppet to automate your infrastructure, you can provision your virtual environment from scratch and deploy all your applications in minute. It’s magical. You've achieved Configuration Management Nirvana. What you've built is repeatable, saves time, increases efficiency and removes human error.
