Behind the name

Automation is a practice which, like the color grey, is full of nuance and precision. There are often no strictly correct or easy answers. Expert advice is often essential in picking the right tools, especially when it comes to the assortment of cloud providers. Cloud Grey brings this nuance and this experience with cutting-edge industry technology to bear on our clients' problems. Also, Cloud Grey's founder is from Vancouver, Canada, which can be a wonderfully cloudy and grey place much of the time!
