Arpeely chopped $140K/month off their cloud bill using a surgical mix of GCP tricks. Committed Use Discounts (CUDs) for high-availability services? Check. Smarter Kubernetes HPA configs? Definitely. Archiving old BigQuery data into GCS Archive? That one alone slashed storage costs 16x.
The real kicker: they rewired their HPA strategy. By capping scale events to 30% (or max 20 pods every 120s), they cut pod counts by 30%—with zero hits to uptime.
