Review AWS network and edge cost efficiency for a selected organization or payer account. Collects EC2-Other, VPC, ELB, and data-transfer spend from Cost Explorer split by member account and usage type so NAT gateway, public IPv4, and transfer charges are separated out of the EC2-Other bucket they hide in, then assesses each ranked account against its own read-only inventory of NAT gateways, Elastic IPs, load balancers, and VPC endpoints together with CloudWatch traffic metrics, and produces an organization-level verdict covering NAT gateway economics against VPC endpoint alternatives, public IPv4 charges and unattached Elastic IPs, idle or low-traffic load balancers, VPC endpoint fit, and cross-AZ and inter-Region transfer patterns, with estimated monthly savings where the evidence supports them.
