What is AWS NAT Instances & NAT Gateways?

by XDK 4. August 2019 06:35

Explanation:

A NAT (Network Address Translation) instance is, like a bastion host, an EC2 instance that lives in your public subnet. A NAT instance, however, allows your private instances outgoing connectivity to the internet while at the same time blocking inbound traffic from the internet.

A NAT (Network Address Translation) Gateways provide the same functionality as a NAT instance, however, a NAT Gateway is an AWS managed NAT service. As a result, these NAT Gateways offer greater availability and bandwidth and require less configuration and administration.

Comparison of NAT Instances and NAT Gateways

Bastion host : A bastion host is a special-purpose computer on a network specifically designed and configured to withstand attacks. The computer generally hosts a single application, for example a proxy server, and all other services are removed or limited to reduce the threat to the computer.
