Which AWS service or feature can provide the EC2 instances with network connections to the internet?

Explanations:

A Gateway endpoint provides a private connection between a VPC and supported AWS services, but it does not provide internet access to EC2 instances in a private subnet.

A NAT gateway allows instances in a private subnet to initiate outbound traffic to the internet while preventing unsolicited inbound traffic, thus providing the necessary internet access.

A Network Load Balancer is used to distribute incoming traffic across multiple targets, but it does not provide internet access for instances in a private subnet.

Amazon Route 53 is a DNS web service that provides domain name resolution but does not facilitate direct internet connectivity for EC2 instances in a private subnet.
