Amazon have done it again. Another small step forward. Another incremental improvement to their offer. Another small reason not to use them crossed off the list. Today, the company announced that their Amazon Web Services product is operating out of a data center in Tokyo. Alongside existing data centers in Singapore, Dublin, California and Virginia, they’re doing an increasingly good job of getting servers close to customers… at least in the Northern Hemisphere. Where’s next? Rio? Sydney? Auckland? Or stick with the top of the globe and go to Bangalore? Or somewhere European, to help Dublin’s “EU West” moniker make sense? Multiple data centers aren’t just about physical proximity and a reduction in network latency, of course. Certain jurisdictions (here in the EU, for one) get very upset at the suggestion of transferring data beyond borders. How interested is Amazon in continuing to cater for the data sovereignty use case?
