is feasible the use of windows instances for the spot offering?

the time to get up and running a windoows instance vary from 10 to 20 minutes, but you get the termination notice 2 minutes before amazon get down the instance so there is not enough reaction time start a windows instance under demand and move the players to that instance.

is there a way to solve this? can i implement my backend on C# and run it on wine under linux?
i can’t use the core version of .net because i’ll be using SignalR and it is not available on the stable version of .net core
