Re: "Oracle accused AWS of a variety of dodgy practices"
Very much so.
Oracle have scrapped every ounce of pork from the DoD barrel - suggesting that there are dodgy practices within AWS maybe (i.e. I can't validate that it was not corrupt) accurate BUT it is an order of magnitude less than the dodgy practices that existing vendors were involved in, including Oracle.
Some of the stories around charges for changes to DoD equipment in data centres managed by third parties are hilarious if it wasn't for the fact that US tax payers were paying for this behaviour.
