NAT gateways (a required component if you want real security) cost like $30/month each and you need at least 2 for HA.

- scarface74 7y agoWell, I’ve got bad news for you, if you think NAT Gateways are required for “real security”, just wait until you enable IPv6 on AWS.....
- kawsper 7y agoCould you elaborate on this?
- scarface74 7y agoWhen you enable IPv6, there is no NATing. All of the IP addresses are public. You can use an Egress only Internet Gateway. https://docs.aws.amazon.com/vpc/latest/userguide/vpc-nat.html https://docs.aws.amazon.com/vpc/latest/userguide/vpc-nat.htm... But technically, your EC2 instance never has a public IP address. You can see for yourself by assigning a public IP address to an ENI attached to your instance and doing an ifconfig. An Internet Gateway is a one to one NAT.
