No one doubs the performance of C++. What I would really like to see is arguments about speed of development, ease of testing, etc. This articles argues alot about language features or libraries, but what about the bigger picture? It is not enough for the HTTP server be fast. It also needs to do REST API, auth, etc. How does that compare to for example node/js.

One C++ advantage is, at 40X the horsepower, they didn't have to deal with scaling configuration right away. They can put that off, and deal with proving their product instead.

The argument is you do not need a load balancer because performance of one host is good enough. But that would become a single point of failure. And thats why AWS is so awesome. Start with an autoscaling group when you create your ec2 instance, you dont really need alot configuration.
