Do I understand correctly that EC2 can be "configured" to automatically add resources when certain conditions occur?

Question

Amazon Web Services

Hello.
Do I understand correctly that on this service there is an opportunity to purchase a certain set of resources with an "automatic" short-term increase in them?
That is, there is a mini-shop with 1000 uniques / day, working on some kind of mini-instance. And in the settings, when a load occurs (for example, when exchanging 1,000,000 goods with 1s), memory and processor power are automatically added?

Answer 1

no, of course it doesn’t turn out to be scaling
in amazon, only horizontal scaling is correct and all that
, that is, the load has increased, launched ten more servers and served everyone,
and you invent some kind of heresy about vertical scaling, which simply rests on one server, then it’s easier to take with Amazon prices powerful cheap Dedik will be ten times cheaper
