To find out where the next AWS regions are going, go to wikipedia and sort countries by GDP, any large country without a region is a target. Obviously there is some massaging happening, like AWS is considering all the nordic countries near Sweden.
Another thing would be if AWS started building smaller regions with only 1 DC. Right now a region requires at least 3 DCs with the AZ model... so that's a lot of capacity to fill.
No offense to you or Israel, but it would be nice to see African interests managed somewhat "locally" whenever possible, with the benefits accrued and distributed locally as well. I think that's a future many people hope for, and it's nice to see an effort towards that direction where possible.
* Biggest problem is that Israel is an Internet cul-de-sac - there aren't any overland Internet links to Arab countries because of politics. Which means that the only people who are going to get great pings are Israelis.
* Sure, there are a ton of Israeli tech companies, but if they're going to spin up instances in an Israeli region, they're going to be low-traffic/requirement dev instances. Production instances are going to be located close to customers, and almost no Israeli tech companies sell to the tiny local market.
* Israeli customs infrastructure has a long way to go before it's probably reliable enough for Amazon to risk investment. Imagine a vital shipment of server hardware getting held up at Ashdod because Histadrut went on strike.... shudder
I refuse to believe that the bean counters at Amazon are ignorant - they've more probably come to the conclusion that it's just not profitable.
