Curious - are AWS's EU clusters subject to EU laws, or US ones? I would've thought that as a US corporation, they'd be subject to both. If the US government has a warrant to snoop on Amazon's customers, it doesn't seem like Amazon has much choice (as a US corporation) but to comply.
Currently the US-of-A believes that US laws _always_ apply, no matter where. However that doesn't jive well with EU privacy laws. For example the easiest way to comply with the German privacy laws ( https://en.wikipedia.org/wiki/Bundesdatenschutzgesetz ) is to host inside of Germany itself (See also: AWS eu-central-1).
