AWS enterprise customers get case managers as points of escalation and this is a generally accepted strategy for almost everyone in enterprise to the extent that I believe customers would be very concerned if this type of customer outreach model was not in place. This does not necessarily mean that this is the same thing as a services style engagement manager either.<p>Note that this does not mean that I think it&#x27;s optimal, but I do mean that a vast majority of enterprises have a form of group-think culturally that makes this approach something that&#x27;s demanded as a standard service offering that is no different than developers expecting APIs from a hosted service.
