Cost Attribution in Shared Infrastructure

Short summary

A practical guide to cost attribution for shared Kubernetes clusters, progressing from no attribution through tagging, show-back, and full charge-back. Covers shared service allocation, burst cost smoothing, and handling untagged resources by assigning them to a platform team. After 3 months of show-back, most teams cut 15-25% of waste.

• •Four-level maturity model: no attribution → tagging → show-back → charge-back
• •Shared services: spread equally for small costs, usage-based for >5% of total spend
• •Untagged resources assigned to platform team to incentivize tagging enforcement
• •Show-back alone typically drives 15-25% waste reduction within 3 months
