At AWS re:Invent, NVIDIA and Amazon Web Services expanded their strategic collaboration with new technology integrations across interconnect technology, cloud infrastructure, open models and physical AI. As part of this expansion, AWS will support NVIDIA NVLink Fusion—a platform for custom AI infrastructure—for deploying its custom-designed silicon, including next-generation Trainium4 chips for inference and agentic AI model training, Graviton CPUs for a broad range of workloads and the Nitro System virtualization infrastructure.

Using NVIDIA NVLink Fusion, AWS will combine NVIDIA NVLink scale-up interconnect and the NVIDIA MGX rack architecture with AWS custom silicon to increase performance and accelerate time to market for its next-generation cloud-scale AI capabilities. AWS is designing Trainium4 to integrate with NVLink and NVIDIA MGX, the first of a multigenerational collaboration between NVIDIA and AWS for NVLink Fusion. AWS has already deployed MGX racks at scale with NVIDIA GPUs. Integrating NVLink Fusion will allow AWS to further simplify deployment and systems management across its platforms.
