Strange one from Amazon. They've always provided cloud infrastructure services for building and launching apps, QuickSight departs from this - it's a ready to use app. The logic must be: more money in apps than infrastructure. Opposite of Google, they have the apps and now want the infrastructure too - I think it's a mistake for Amazon to go down this route, there is too much competition in this space and so far play…
AWS generally tends to complement its offerings such that they can avoid most of existing users of one or more services from looking at other alternates.
