Optimizing Network Costs

Network charges are not a resource you provisioned, they are a consequence of the path your packets take. This lesson covers the 3 shapes of network charge, how to read them in the bill, and the arithmetic behind NAT gateways, VPC endpoints, cross-AZ traffic, and Transit Gateway.

Intermediate 27 minutes 5 Learning Objectives
  1. Separate the 3 shapes of network charge: hourly resource charges, per-GB processing charges, and per-GB data transfer charges
  2. Identify network spend in the Cost and Usage Report from the usage type on each line item
  3. Calculate the break-even point between a NAT gateway and a VPC endpoint for a given monthly volume
  4. Explain why same-AZ, cross-AZ, cross-Region, and internet-bound traffic are priced differently and which direction is billed
  5. Choose the right tool to find network spend: Cost Explorer, the Cost and Usage Report, VPC flow logs, and Cost Anomaly Detection
