and what is the feature of cloud hosting?
As always in money.
For example, the website gives 1 € each visitor profits.
The site is visited by 100 people a day.
But I gave a TV ad and the website came 1 million people in one day.
And brought me 1 million rubles, Yes some of the money I gave to Amazon cloud.
But the website did not lie at the peak load, and worked quietly.
