Hi @karthick_k ,
I'm not a Canvas developer but I wanted to give you some response so you would know your question has not gone unnoticed. I believe most would choose a Linux distribution as it is the preferred choice for web servers and development (safe enough statement since you didn't list OSX
). As for the version, I'll go out on a limb and suggest just starting with the latest Ubuntu version if that's the distribution/variant you prefer. Now if you were asking which variant of Linux though, well that's an entirely different conversation
You'll find much more information on the Github page as well. There is even an Installation Quick Start that speaks to operating systems.
