Google has been doing these sort of blog posts for years. Some engineer wites up an entry about how they are doing research using terabytes or petabytes of data. And then they end by saying you should work at Google. So nowadays, I don't care about any of what Google does. […] MapReduce? Great, they've been sitting on this technology for a decade. Good for them. It doesn't matter to me. But the world has changed, and Google can't seem to keep up. Amazon has become the polar opposite of Google, empowering every developer on the planet to make incredible technology. Want MapReduce? Amazon has you covered. Want to play with terabytes of data like it ain't no thing? Check. Want to launch thousands of servers to handle a tough computation? Check, check, and check. Want to launch thousands of human brains to solve otherwise unassailable problems? No problem. Heck, want to simply send email to your users? They have that too.
