4. What is a NAT device?
5. Device Comparison NAT Gateways NAT Instances PrivateLink Management Fully managed Self-managed Fully managed Not for general purpose use Bandwidth Up to 100Gbps Depends on instance type Up to 100Gbps Hourly cost $0.045/hr Depends on instance type $0.01/hr Egress cost $0.045/GB $0.0 $0.01/GB - $0.004/GB, depending on volume Ingress cost $0.045/GB $0.0 $0.01 /GB- $0.004/GB, depending on volume Data transfer cost $0.09/GB - $0.05/GB, depending on volume $0.09/GB - $0.05/GB, depending on volume N/A
6. Data transfer pricing scenario Cost of transferring 1PB egress, 1PB ingress to/from the Internet through each. Demo using the AWS Pricing Calculator https://calculator.aws/
7. NAT Gateway: $147,284.05 USD NAT instance: $55,091.20 USD PrivateLink: $16,784.52 USD Data transfer pricing scenario
