What is inside highly loaded services?

By occupation, I am interested in various aspects of the implementation of highly loaded services, the question arose about what is the best way to make a service designed for a multi-million website. The correct answer of course depends on who will develop it, that is, who knows what language well.

But it was interesting to stumble upon such a tablet, which actually shows the development trends of highload structures.



A little later, I will make the same tablet for Russian startups, I think many will be interested in what they work on.

Also, who is interested in this topic, like me, I recommend periodically looking at the
highscalability.com website, thanks

for the kind people raising karma to 1, which allowed this first post to be written;) for
example 2, some kind of layout problems.
