Filter for egress in each cloud's cost dashboard

The biggest egress wins come from finding where the bill spikes. Each cloud's billing console hides bandwidth charges under different labels. The exact filters to apply:

AWS Cost Explorer

  1. Open Cost Explorer in the Billing console.
  2. Set Group by = Usage Type Group.
  3. Filter Usage Type to include any of: DataTransfer-Out-Bytes, DataTransfer-Regional-Bytes, NatGateway-Bytes, DataTransfer-ApSe1-Bytes (etc per region).
  4. Switch to monthly granularity and look at the last 6 months to spot anomalies.
  5. Drill in: Group by Service to see whether the spike came from S3, EC2, RDS, or CloudFront.

The Cost and Usage Report (CUR) exposes finer-grained line items if Cost Explorer is not enough. Enable CUR with Athena integration for SQL queries against your bill.

GCP Billing

  1. Open Billing › Reports.
  2. Set Group by = SKU.
  3. Filter SKU contains any of: Egress, Network Internet, CDN cache fill, Inter-region.
  4. Cross-region traffic shows as Networking Inter region egress SKU lines; these are often missed.
  5. Export billing data to BigQuery for SQL queries. The resource.name column reveals which VM / LB caused the egress.

Azure Cost Management

  1. Open Cost Management + Billing › Cost analysis.
  2. Set Group by = Meter category.
  3. Filter to Bandwidth. Drill in to see Zone 1 / Zone 2 / Zone 3 / inter-region split.
  4. NAT Gateway shows under Virtual Network NAT meter category.
  5. Export to Storage for daily granularity. The MeterSubCategory column has the cleanest egress vs ingress vs intra-region split.
