AI is moving beyond training, and inference is now the biggest challenge enterprises must solve. In this episode of Tech Field Day Takeaways, Alastair Cooke shares his biggest lessons from AI Infrastructure Field Day 5, explaining why storage has become central to AI performance, why GPU efficiency matters more than raw utilization, and how KV cache optimization can dramatically improve inference speed. He also explores why data placement is becoming critical as AI scales across cloud and edge environments, and why governance, identity, security, and AI gateways will define the next generation of enterprise AI infrastructure. If your organization is preparing for production-scale agentic AI, these are the infrastructure challenges you need to understand.
