Dumb article. Will save everyone a click:

  1. lower level languages
  2. higher/wider concurrency
  3. faster auto-scaling

The same formula for every platform operating out there. What they don't talk about is efficiency, which is always the most juicy part of these kinds of writeups. You can scale anything to do 50b messages with enough money and resources, but how efficient is it?
