I have wondered this too. Oracle sells their database, but they also sell ERP/CRM/other TLA applications built on top of it. Amazon could do the same thing. And

I have wondered this too. Oracle sells their database, but they also sell ERP/CRM/other TLA applications built on top of it. Amazon could do the same thing. And I think every batch of new AWS announcements they creep a little further up and up. Their IoT platform seems like an almost-there example. It is targeting just one vertical (sort of---it depends on how big IoT becomes I guess), and it ties together other lower-level offerings. When I look at their IoT product I think "I can combine those services myself." But of course that is what programmers always think. :-)
