If you spend some of your spare time on categorizing these projects and discard such ordinary things as second-rate online stores while roughly grouping what is left, you can come up with an approximate classification. It includes four types of high load:

A small optimized kit of ARM chip commands is perfect for mobile devices. Thanks to lower power consumption, it is very popular today for being used in smartphones and tablets. However, recently there has been a lot of talk about the ARM chips being introduced into the area entirely occupied by Intel — the servers.
