How to use Amazon VPS?

Question

System administration

Hey!
Got a few instances from Amazon. They took 1 dollar. As I understand it, this is a free account, or something like that.
Amazon gave me a key in .pem format and a login like e2as-es or something like that... Because
of the complicated interface, I didn't have time to get into it.
1) Tell me how to enter the server by root.
2) Does Amazon give an unlimited number of instances per dollar, or will a one-time bill for $9099 come sometime?
3) How to delete instances?

Answer 1

The dollar was withdrawn not for use, but for checking the card.
A free account on Amazon is free only within the quota for free accounts.
one:

ssh -i /путь/ваш_ключ [email protected]_инстанса
sudo bash
# или
su
# зависит от OS инстанса

If you are on Free Tier, and use 1 (one) t2.Micro instance, while keeping within Free Tier limits in terms of traffic and BlockStorage, then you will not receive any invoice for payment.
If you graduate to Free Tier, you will only be billed for the excess, not for all resources.
