"As 2025 comes to an end, it seems fitting to look at how Microsoft's Azure hyperscale cloud is planning to address the second half of the decade. As has become traditional, Azure CTO Mark Russinovich gave his usual look at that future in his presentations at Ignite, this time split into two separate talks on infrastructure and software. The first presentation looked at how the underlying infrastructure of Azure is developing and how the software you use is adapting to use the new hardware."
"That abstraction is both a strength and weakness of the hyperscale cloud. Microsoft continually upgrades all aspects of its hardware without affecting our code but we are forced to either wait for the cloud platform to make those innovations visible to everyone, or to move code to any of a handful of regions that have new hardware first, increasing the risks that come from reduced redundancy options."
"Cooling CPUs with microfluidics Russinovich's first presentation took a layered approach to Azure, starting with how its data centers are evolving. Certainly, the scale of the platform is impressive: It now has more than 70 regions and over 400 data centers. They're linked by more than 600,000 kilometers of fiber, including links across the oceans and around the continents, with major population centers all part of the same network."
Azure operates more than 70 regions and over 400 data centers interconnected by more than 600,000 kilometers of fiber. Hyperscale infrastructure upgrades hardware continuously while exposing only virtual APIs to users. Customers face a choice to wait for platform-wide hardware availability or move workloads to a few regions with new hardware, which reduces redundancy and increases risk. Data center evolution is driving new cooling approaches such as microfluidic CPU cooling to support higher power density. Investments in bare-metal servers and improved storage aim to deliver better performance, lower latency, and greater efficiency for cloud workloads.
