The Costs Nobody Owns: Allocating Shared RDS, Network, and Storage by Real Usage

Shared clusters, databases, and queues have no single owner. Egress charges, cross-AZ transfer, and NAT gateways show up on the bill with no source data attached. Tags cannot split what was never separable, which is why most cloud spend goes unattributed at the unit level.

This session shows how to allocate shared infrastructure by actual consumption observed at the source, so finance gets a real chargeback and engineering stops arguing over who owns the RDS instance.
