I like that it is easy for me as an admin user with little experience in Linux server administration, but still able understand how things work (and get help when needed). It's not free software so you need payed license if your plan doesn't have enough resources or budget - otherwise there are some limitations of what can be done using this tool which makes sense since its purpose isn;t just about being cheap/free solution without any restrictions at all! If price fits into plans then use vpssim even though other solutions exist out-of box such us CloudLinux etc..
