My fear is Azure will build solutions specific for a customer which might never be used by other customers. So that solution is a special case in a homogeneous cloud platform with all its own problems. For example, I feel I can trust S3 because of its simplicity and the sheer amount of systems depending on the same simple functionality of S3 I am using. If I would get a special feature in S3 just for my use case, there is no guarantee others will use that feature and it will be as battle hardened as the generic features.
