Having said that, it is not popular because it is not cost effectivr but I would not trust any hosting/cloud service and would definitely have all my business data in at least 2 different ones, run my services on two different major OSes (probably Linux and FreeBSD), as well as a separate company for 2 different domains that are known by my customers (and apps, for autoretry).

But I am not in a position to take those decisions anyway.
