Pioneering Performance and Scale: Azure’s Latest Compute Innovations
Microsoft Azure just dropped some serious compute upgrades at Build 2025. These updates push cloud performance and scalability to new heights. If you’re into cloud tech, this is a must-know.
What’s New: Meet Azure Boost and Network-Optimized VMs
Azure Boost is the star of the show. It’s a proprietary system that offloads virtualization tasks to specialized hardware, smashing storage performance records. For remote storage, it hits 800K IOPS and 16 GB/s throughput. Local storage? Even crazier—6.6M IOPS and 36 GB/s throughput.
Scott Guthrie, Microsoft’s Cloud + AI EVP, called it “a game-changer for demanding workloads.”
On the networking front, Azure introduced new VM series—Dnsv6 and Ensv6—that leverage hardware acceleration to boost network throughput up to 200 Gbps. This means ultra-low latency and massive bandwidth for edge computing or video streaming.
Major Updates: Fxv2 VM Series and Guest RDMA for GPUs
The Fxv2 VM series is now generally available, designed for CPU-heavy tasks like databases and data analytics. These VMs offer up to 50% better CPU performance, support up to 96 vCPUs, and pack 1,832 GiB memory. NVMe support delivers remote storage speeds of 400K IOPS and 125 GB/s throughput.
Azure CTO Mark Russinovich demonstrated guest RDMA for NVIDIA GPUDirect. This tech lets GPUs communicate directly over the network, bypassing CPU bottlenecks. The result? Up to 11x bandwidth increase and lower latency for GPU-heavy workloads.
“Azure Boost is designed to cater to organizations looking to push the boundaries of what’s possible in storage and networking.”
Scaling Made Easy: Azure Compute Fleet and Instance Mix
Scaling compute resources just got smarter with Azure Compute Fleet. It allows businesses to tap into a broad pool of compute resources across SKUs, regions, and pricing models. This flexibility suits fluctuating workloads like e-commerce or financial trading.
Compute Fleet automates resource allocation, so you spend less time managing infrastructure and more time innovating.
Alongside this, the new Instance Mix feature for Virtual Machine Scale Sets lets you specify multiple VM sizes in one group. It dynamically picks the best VM sizes based on capacity, reducing deployment complexity and optimizing availability.
Why This Matters
- Industry-leading storage and network performance
- Ultra-low latency for distributed systems
- Flexible, cost-effective scaling for dynamic workloads
- Improved security with 100% isolation between Azure Boost and customer workloads
“By prioritizing performance, scalability, and cost efficiency, Microsoft reaffirms its role as a leader in cloud innovation.”
The Takeaway
Azure’s latest compute innovations set a new bar for cloud performance. Whether you’re running data-intensive apps or need flexible scaling, these updates deliver. Expect faster storage, blazing network speeds, and smarter scaling tools to power your next-gen workloads.
Stay tuned—Microsoft is just getting started with pushing cloud boundaries.
