The need for automated environmental validation in IT

action 002.jpgI was recently reading the post When disaster strikes: How IT process automation helps you recover fast and it got me thinking about the need for automated environmental validation. Recovering fast may not be good enough if the recovery destination environment has changed.

 

In the software space, you can use jUnit or nUnit to codify the limits of the code and make sure it works, and breaks as defined. It can be a very useful component of a test first unit testing approach.

 

I was wondering if infrastructure automation efforts should include a similar capability that we can automatically test an environment to ensure its characteristics are up-to-snuff, before and after we make a change. These tests could either be run periodically, or as part of a promotion to production process.

 

Automating this validation would remove the human element from this tedious step. It seems like this would be a useful and possibly necessary step for cloud deployments, since those environments are dynamic and beyond the scope (and understanding) of the person who wrote the original programs. Maybe this is commonly done, but I've not talked to many who attack this issue proactively.
