When I started dabbling with the cloud, I didn't spare two thoughts about tags. Sure, they sounded great, just I never used them personally.

I had resources that I couldn't sort by projection, by squad, or even past environs. I'm sure many of yous can relate to looking at your Amazon EC2 instances and non being able to figure out what belongs to which project. Everything could exist solved if I just knew that Amazon EC2 had been provisioned and was not running the tags that were deemed mandatory.
