good luck to them
if you trust your telco performance, local and not so local backhoes and can afford a big pipe. Oh, and class of data might matter too. OTOH, Oracle are a trifle expensive. My recent work experience suggested Oracle DBAs were not impressed by support services and pricing to say the least. Always wondered why the Oracle compatibilty mode of Postgress was not used more to break the lock-in. Is Postgress performance too slow, because my limited experience suggests it performs very well. Regardless, Amazon are providing an alternative for some market segments which is A Good Thing.
