## Resource

In this episode, Lucas and Luna break down how cloud providers like AWS, Azure, and Google Cloud are redesigning the physical network topology of GPU clusters to support large-scale AI training. They examine the shift from traditional leaf-spine architectures to multi-dimensional torus networks, the rise of 'superpod' designs from NVIDIA, and what this means for latency and bottlenecks. The conversation uses a concrete example: a 10,000-GPU cluster running a large language model training job, comparing the communication overhead in a standard topology versus a 3D torus. They also touch on why this matters for enterprise customers planning AI workloads in 2026. #CloudComputing #GPUClusters #AITraining #NetworkTopology #AWS #Azure #GoogleCloud #NVIDIA #TorusNetwork #Superpod #Latency #Infrastructure #Technology #BusinessPodcast #FexingoBusiness #CloudInfrastructure #TechTrends2026 #AIWorkloads Keep every episode free: buymeacoffee.com/fexingo
