Enabling internet access in a VPC

1. Create an internet gateway and attach it to your VPC.

2. Add a route to your subnet's route table that directs internet-bound traffic to the internet gateway.

3. Ensure that instances in your subnet have a globally unique IP address (public IPv4 address, Elastic IP address, or IPv6 address).

4. Ensure that your network access control lists and security group rules allow the relevant traffic to flow to and from your instance.
