The NAT Host allows servers in private VPC subnets to communicate outside of the VPC, which is necessary for private servers to reach RightScale servers in order to complete the booting process and to provide admin access. Applications that make API calls to remote services also need internet access. This server can also be used as a jump/bastion host to gain access to your private servers.
