I was looking at Azure documentation but I couldn't find what type of operating system does Azure for MySQL and Azure Redis Cache use. I assume that for redis it should be a must to use Ubuntu but can't find any details about underlying infrastructure. I may have missed it so if you can please refer me to it.
I want to know what are the difference between my current environment and Azure managed DBs and also what control I would lose if moving to managed instances as opposed to the many benefits that I would gain before going that way.
