Been saying this for years. People build these ridiculous contraptions: Spark/Hadoop, key value stores, NoSQL, microservices, distributed filesystems all over the place, fault tolerance and so on. Then you ask "how much data and traffic do you have?" Nearly always you get an answer where a single machine and properly designed software would be more than enough. I figure, in a way we should be thankful for this cluelesness. If people had any clue whatsoever, IT employment would shrink by a factor of at least 3, and salaries would drop pretty massively as well.
