    Somebody explain to me how according to C the instance which is scaled will get the traffic? You need to route the traffic to the 2nd, 3rd instance etc. Therefore you need a load balancer which is not there. Actually in case of C you might have a huge bill at the end of the month because the instances would scale and they wouldn’t reduce the load. The load would still be routed to the original instance.

    Definitely, B is the only possible answer. Not ideal, but possible. Because you route the content to other locations which then take some load off.
