If you are using the services of AWS you should be careful about some services. It is possible that you may want a certificate for your application. You may use free certificate like let’s encrypt but AWS is offering a “Certificate Manager” and you can find it like any other services:

400$/month per private certificate

But, on the pricing page, you can find that this service cost 400$/month, no matter if you use it or not, it will take you the price of renting a car.

No way to delete or stop this recurring amount of money from the account

On the documentation, you can find that the service will stop “until you delete the CA”. I can tell you that this information is not really true as this service still take money without the CA. So additionally this service have a very not predictable way of taking money, and you don’t really know when it will stop, even if you check there is no certificate and you read carefully the documentation.
