we are the Cloud, you will adapt to service us. RESISTANCE IS FUTILE
As a technician that handles about 50 clients varying between 10 and 500 users each, I can tell you that if you don't like the cloud you should just go spend money on therapy and try and get over it since we are going to the cloud whether you like it or not.
It's a better solution to almost every enterprise problem than on-premise anything. Do outages occur? Yep, whats worse tho, an outage that microsoft spends it's time fixing or one you do? Because they will still happen to you even if you don't have cloud based anything. Power goes out, how long does your UPS last, bro?
As technology advances outages will become so short and unnoticeable that all you whiners will finally have something to point to and go "oh, I actually didn't know the first thing about what I was complaining about".
Enjoy being bad at computers tho.
