Power is AI infrastructure’s inescapable constraint. How many tokens an AI factory can generate within a fixed power budget determines its revenue and profitability. Because of this, performance per watt — a metric that can’t be gamed, only earned through real-world results — is the foundation for AI factories. As agentic AI drives token demand […]

C4N, now GA: Delivering cloud’s highest per vCPU network and block storage I/O for x86 workloads
Google CloudAs organizations scale modern workloads — from high-throughput databases and network/security appliances to real-time analytics and AI/ML inference — network and block storage performance can quickly become a bottleneck. Standard virtual machines often struggle to balance compute efficiency with the high-volume data-transfer demands of these applications. At Google Cloud Next ‘26, we announced C4N in preview, our first network- and…
