How automating cloud operations accelerated time to market at NU
summary
Nubank describes moving core production to Spot by NetApp with 70–80% Spot usage and an average 60% compute savings on AWS, solving Spot volatility by using automatic OD fallback and return to Spot, segregating workloads with virtual node groups (Spot-only vs On‑Demand) to protect latency‑sensitive Kafka-backed payments, adopting mixed ARM/Intel node strategies, and driving decisions from observability into automation via Spot APIs/SDKs rather than UI to keep costs predictable while maintaining SLAs.
