1. AWS never provide any support to their clients even if the problem is from us for that you have to pay them back.
2. AWS blocks mail SMTP port and you will request to enable but they will keep it blocked and force you to buy their mail service separately.
3. AWS response time is not good and aws is also not easy to configure whereas google and another cloud us much better.
4. aws will charge you a lot of extra money from your card so never link your card with them first they will say 100$/m will cost your server but later they will charge you 300$ +.

My Personal Advce don’t use aws ec2 at all.
