Five years ago, most cloud workloads ran on a single CPU architecture by default. No more. Today every major hyperscaler offers Arm-based compute, so what began as an option is now a core part of modern cloud infrastructure. The reason is straightforward. As AI workloads scale and cloud demand continues to grow, providers are under pressure to deliver more performance while controlling power consumption, cost, and datacenter footprint. Meeting those demands is forcing a rethink of the hardware foundations of the cloud. Arm-based silicon now powers many of these platforms. AWS offers Graviton processors, Google Cloud introduced Axion, Microsoft Azure runs Cobalt-based instances, and Oracle Cloud Infrastructure deploys Ampere Arm processors. Across these environments, the focus is consistent: improving performance while reducing power consumption and overall cost. The economics can be significant.…
