- three in the US (1 in Virginia, one in Oregon, one in Northern California)
- two in Europe (Dublin and Frankfurt)
- four in Asia (Singapore, Tokyo, Sydney, Seoul)
- one in South America (São Paolo)
and both Montreal and India announced. So by part way through 2017, the "numbers" would be sort of comparable but the real factors are your latency requirements, data sovereignty (hello Germany!) and the features you need (and not all features are available in all regions!).
The German laws on that are interesting, and I don’t think Google’s Cloud can every comply with them – because you may not give any foreign third party access to personally identifiable data, or move it to a country with lower data privacy laws, hosting it in a Google-provided system would be quite problematic.
Although the laws are a pain (including for me, even if you just host an IRC bouncer for a bunch of people they become quite interesting), I wouldn’t trade them away for anything, because they help ensure that all spying that happens can be democratically regulated by those who are spied upon.
