Every engineering organization faces the same recurring task: reporting on last month’s cloud invoice. The formats vary — Notion pages, PowerPoint decks, Slack threads — but the questions remain the same:
  • What happened last month?
  • Why did the cost increase?
  • Where are the anomalies?
This work typically falls to senior SREs or infrastructure leads. It’s time-consuming, repetitive, and distracts from higher-priority engineering work.
