Microsoft Ventures into Networking Hardware Development to Enhance Azure Infrastructure


  • Microsoft’s new networking card will speed up Azure servers, cutting reliance on Nvidia.
  • It boosts AI training and could shake up the market for server gear.
  • Led by Pradeep Sindhu, Microsoft follows the trend of making custom silicon for data centers.

Microsoft has embarked on developing its networking card to bolster its datacenter capabilities and reduce reliance on external vendors. This development marks a significant step for the tech giant as it seeks to optimize its Azure infrastructure and diversify its technology stack.

Microsoft’s foray into custom silicon

After the recent unveiling of its 128-core datacenter CPU and Maia 100 GPU tailored for artificial intelligence (AI) workloads, Microsoft is now venturing into networking hardware intending to speed up its datacenters. The company’s endeavor to create its networking card underscores its commitment to innovation and self-sufficiency in key technology domains.

Microsoft’s acquisition of Fungible, a developer of data processing units (DPUs), approximately a year ago has positioned the company advantageously in networking technologies. With Fungible’s expertise and intellectual property in DPUs, which compete with industry players like AMD’s Pensando and Nvidia’s Mellanox divisions, Microsoft is well-equipped to design datacenter-grade networking gear tailored for bandwidth-intensive AI training workloads.

Pradeep Sindhu, renowned as the co-founder of Juniper Networks and founder of Fungible, now spearheads the development of Microsoft’s datacenter networking processors. His wealth of experience in networking gear lends credibility to Microsoft’s endeavor, emphasizing the company’s serious commitment to this project.

The introduction of Microsoft’s networking card promises to significantly enhance the performance and efficiency of Azure servers. Currently powered by Intel CPUs and Nvidia GPUs, Azure servers are poised to integrate Microsoft’s and GPUs in the future. Microsoft aims to streamline data flow within its datacenters by optimizing networking components, improving overall efficiency, and reducing latency.

Impact on AI model training

High-performance networking gear is indispensable for datacenters, especially concerning AI model training, which demands vast amounts of data processing capabilities. Microsoft’s networking card aims to alleviate network traffic congestion, thereby accelerating AI model development and rendering the process more cost-effective. This development aligns with industry trends towards custom silicon, as other major cloud providers, including Amazon Web Services (AWS) and Google, are also investing in developing their AI processors and networking infrastructure.

The potential impact of Microsoft’s networking card on Nvidia’s sales of server networking gear cannot be overlooked. Nvidia’s server networking gear is projected to generate over $10 billion annually, and Microsoft’s entry into this domain could disrupt the market landscape. However, the ultimate success of Microsoft’s networking card remains to be seen, as custom silicon development entails significant time and resources.

While the initial results of Microsoft’s networking card endeavor may still be years away, the company remains committed to its long-term vision of self-reliance and innovation. In the interim, Microsoft will continue collaborating with external vendors for hardware supply, but the trajectory indicates a gradual shift towards a more self-sufficient model.

Microsoft’s foray into networking hardware development represents a pivotal moment in the evolution of its Azure infrastructure. With a focus on optimizing every layer of its technology stack, Microsoft is poised to enhance the efficiency and performance of its datacenters, ultimately benefiting its customers and advancing the field of AI development.
