Yep. I'm one of 2 Devops at an R&D company with about 100 employees. They need these services for development, if an important service goes down you can multiply that downtime by 100, turning hours into man-days and days into man-months. K8 is simply the easiest way to reduce the risk of having to plead for your job.

I guess most businesses are smaller than this, but at what size do you start to need reliability for your internal services?
