My question - how badly did Amazon get burnt by using Oracle?
In databases in particular Amazon seems to be on a huge kick to not have to pay anyone else. Even if they end up with a bunch of quasi-overlapping products (SimpleDB, DynamoDB, MongoDB) they just seem very aggressive here. At this rate they are going to have 10+ database offerings in the future.
It's easier for AWS for accommodate all their customer's needs (MySQL, MongoDB, Postgres) and reduce the cost of switching than it is to convince them to rewrite an application or legacy application to leverage say DynamoDB. The benefit of DynamoDB is great, but it's just one slice of the computing pie.
