News from the jungle. Amazon is now offering an explicit relational database cloud service, RDS. It is MySql 5.1, so calling it "relational" is a bit of a stretch, but it is some good news.
I had the temerity to suggest that they offer SSD storage as an explicit option, so that real database wonks can build real BCNF applications. Got back a personalized auto reply, which said that "An AWS representative will reach out as soon as possible to address your questions about cloud computing and Amazon Web Services." I am on tenterhooks.
