“We carried out in depth benchmarking of the brand new Cobalt 100 VMs for containerized utility workloads working on AKS and noticed measurable price-performance positive factors in comparison with Azure’s previous-generation Arm-based VM sequence, with enhancements evident throughout each throughput and cost-efficiency metrics. Following these outcomes, we have now migrated 70% of our AKS workloads to Cobalt 100 VMs and are within the strategy of migrating the remaining 30%.”
— Gopala Krishna Padidadakala, Sr Director of Cloud Engineering, Sprinklr
“Temenos is proud to set a brand new business benchmark for scalable, AI-powered banking on Microsoft Azure, leveraging the breakthrough efficiency of Cobalt 100 VMs. The mix of Temenos’ cloud-native platform and Azure’s Arm-based Cobalt 100 VMs allowed us to realize over 40% effectivity enchancment in comparison with the 2024 benchmark train, enabling banks to run demanding workloads with higher effectivity and sustainability. This collaboration empowers monetary establishments to innovate quicker and scale securely, reworking the way forward for digital banking.”
— Eugene Khmelevsky, Head of Structure and Knowledge, Temenos
Microsoft’s personal providers are additionally benefiting from the adoption of Cobalt 100 VMs. The deployment of Cobalt 100 VMs for Microsoft’s providers demonstrates its capability to help large-scale, mission-critical purposes.
Microsoft Groups has achieved as much as 45% higher efficiency utilizing these VMs than beforehand doable. Groups is a latency-sensitive utility that serves tens of millions of customers worldwide, and the flexibility to course of requests extra effectively has a direct impression on consumer expertise. The media processor functionality in Groups—supporting audio/video streaming—runs on Cobalt 100 VMs with decrease compute footprint. That interprets to useful resource discount of as much as 35% fewer compute cores wanted for the workload. Cobalt 100 VMs unlock distinctive effectivity, empowering groups to realize extra, quicker, with fewer sources.
Microsoft Defender for Endpoint (MDE) is a cloud-native safety service with a whole lot of microservices that carry out menace detection, information evaluation, and safety at large scale. We now have seen 40% higher efficiency in MDE’s cyber information curator, working on Cobalt 100 VMs. Curator teams high-volume information into partitions in actual time for quick, scalable processing. Quicker processing and better throughput translate to raised consumer experiences, together with quicker menace response in MDE.
These outcomes underscore the worth of Microsoft’s strategy to architect and develop personalized infrastructure; Cobalt 100 isn’t just a brand new sort of basic compute VM, however some of the optimized compute merchandise in Azure. Whether or not it’s accelerating product growth, scaling analytics platforms, or enhancing consumer experiences, clients are discovering that the mix of efficiency, effectivity, and cost-effectiveness makes Cobalt 100 VMs a compelling selection for contemporary cloud workloads.
Cobalt 100 demonstrates Microsoft’s end-to-end programs technique in apply. By designing the CPU in-house and optimizing it for Azure’s infrastructure, Microsoft has created a tightly built-in infrastructure that delivers constant efficiency throughout a wide range of cloud situations. This strategy permits for higher management over energy consumption, thermal administration, and workload distribution, leading to a strong and environment friendly cloud atmosphere.

As extra organizations look to modernize their infrastructure and undertake cloud-native applied sciences, the demand for extremely performant and energy-efficient compute sources will proceed to develop. Azure Cobalt 100 VMs are well-positioned to satisfy this demand, providing a scalable and sustainable answer for a variety of purposes.
By delivering quicker, extra environment friendly computing, Azure Cobalt 100 empowers organizations to push the boundaries of what’s doable with higher worth efficiency throughout business use instances of their respective fields.
