## Resource

Episode 101 of Cloud Computing with Fexingo uncovers a new hidden charge creeping into cloud bills: CPU cache access fees. Lucas and Luna explain how providers like AWS and Azure are starting to charge premium rates for instances that guarantee L3 cache capacity, turning what was once a shared resource into a metered one. They cite a 15-20% price jump for cache-reserved instances and discuss how this impacts high-frequency trading, real-time analytics, and AI inference workloads. The hosts walk through a real-world example: a trading firm that saw a 30% increase in compute costs after migrating to cache-guaranteed instances. They also explore workarounds, including NUMA-aware scheduling and bare-metal alternatives. This episode drills into one specific billing line item that most engineers overlook, offering actionable insight for anyone managing cloud infrastructure budgets. #CloudComputing #AWSCost #AzureBilling #CPUCalculation #L3Cache #CloudPricing #HiddenFees #FinOps #Infrastructure #CloudBills #HighFrequencyTrading #RealTimeAnalytics #AIInference #NUMA #Technology #FexingoBusiness #BusinessPodcast #CloudInfrastructure Keep every episode free: buymeacoffee.com/fexingo
