To provide VMs with outbound internet connectivity in AWS using a private subnet, the administrator needs to create the following components in the VPC:
* Private Subnet: A private subnet is required to house the VMs that need outbound internet access but do not require direct inbound access from the internet.
* NAT Gateway: A NAT (Network Address Translation) Gateway is necessary to allow instances in the private subnet to connect to the internet or other AWS services while preventing the internet from initiating a connection with those instances.
* Public EIP (Elastic IP Address): An EIP is associated with the NAT Gateway to provide a persistent public IP address that allows outbound internet traffic from the private subnet to be routed correctly.
* Route Table: A route table is configured to route traffic from the private subnet to the NAT Gateway for outbound internet access.
