You should not make your own technology judgements based solely on what other people are using. There's too many people jumping on the cloud bandwagon who have no clue what they're doing.
Making technology decisions based on what others are doing is the fastest way to make minor decisions. There's immense value in asking "what does company x do?" choosing that option, and moving on. In my experience time deliberating is time wasted--it's better to make a decision and move on. You can (and should) change later.

Sure, but a minor decision is who prints your business stationery or what kind of toilet paper to buy.
What hardware/networking platform to build your service on is not a minor decision. It will fundamentally affect the architecture of your entire system, and getting the decision wrong will potentially be expensive-with-a-capital-Failed-Company.
