Cloud services have come a long way. Not trying to diss the article, but scaling CRUD app for 250k/sec is not as difficult as it used to be. It mainly comes down to how you manage state in your architecture. Back when I was @ yahoo, serving 10k concurrent request from single server used to be such a big deal. Now, hardly anyone thinks about. Most of the reliability/fault tolerance/auto scaling features comes from underlying AWS/GCP services. We just need to write decent microservice to glue these things together and voila!
