Microsoft\u2019s own services are also benefiting from the adoption of Cobalt 100 VMs. The deployment of Cobalt 100 VMs for Microsoft’s services demonstrates its ability to support large-scale, mission-critical applications.<\/p>\n\n\n\n

Microsoft Teams<\/strong> has achieved up to 45% better performance<\/strong><\/a> using these VMs than previously possible. Teams is a latency-sensitive application that serves millions of users worldwide, and the ability to process requests more efficiently has a direct impact on user experience. The media processor capability in Teams\u2014supporting audio\/video streaming\u2014runs on Cobalt 100 VMs with lower compute footprint. That translates to resource reduction of up to 35% fewer compute cores<\/strong> needed for the workload. Cobalt 100 VMs unlock exceptional efficiency, empowering teams to achieve more, faster, with fewer resources.<\/p>\n\n\n\n

Microsoft Defender for Endpoint (MDE)<\/strong> is a cloud-native security service with hundreds of microservices that perform threat detection, data analysis, and protection at massive scale. We have seen 40% better performance in MDE\u2019s cyber data curator<\/strong>, running on Cobalt 100 VMs. Curator groups high-volume data into partitions in real time for fast, scalable processing. Faster processing and higher throughput translate to better user experiences, including faster threat response in MDE.<\/p>\n\n\n\n

These results underscore the value of Microsoft’s approach to architect and develop customized infrastructure; Cobalt 100 is not just a new type of general compute VM, but one of the most optimized compute products in Azure. Whether it\u2019s accelerating product development, scaling analytics platforms, or improving user experiences, customers are finding that the combination of performance, efficiency, and cost-effectiveness makes Cobalt 100 VMs a compelling choice for modern cloud workloads.<\/p>\n\n\n\n

Cobalt 100 demonstrates Microsoft\u2019s end-to-end systems strategy in practice. By designing the CPU in-house and optimizing it for Azure\u2019s infrastructure, Microsoft has created a tightly integrated infrastructure that delivers consistent performance across a variety of cloud scenarios. This approach allows for better control over power consumption, thermal management, and workload distribution, resulting in a powerful and efficient cloud environment.<\/p>\n\n\n
