NAT Gateways
It has the same purpose as a NAT Instance but instead, this has much less configuration, higher bandwidth and better availability.
You are charged for creating and using a NAT gateway in your account.
Each NAT gateway is created in a specific Availability Zone and implemented with redundancy in that zone.
To create an Availability Zone-independent architecture, create a NAT gateway in each Availability Zone and configure your routing to ensure that resources use the NAT gateway in the same Availability Zone.
