Background and Issues
Azure is Microsoft's flagship cloud infrastructure. As of 2025, traditional infrastructure is reaching its limits amid explosive growth in demand for AI and large-scale data processing. As an engineer, you're likely facing challenges such as inefficient cooling in data centers, performance overhead caused by virtualization, and storage latency.
For example, AI training requires massive computing resources, and server heat generation becomes a bottleneck. Traditional air-cooling systems consume enormous amounts of energy and have a significant environmental impact. Furthermore, the lack of bare-metal environments limits the use of custom hardware, making flexible architecture design difficult. Furthermore, insufficient storage IOPS (Input/Output Operations Per Second) can cause delays in applications requiring real-time processing.
These challenges are not simply hardware issues, but manifest as overall system constraints. As Azure CTO Mark Russinovich pointed out in his presentation, infrastructure innovation is the key to overcoming these constraints. From an engineer's perspective, resolving these constraints will dramatically improve the reliability and scalability of the system.
Technical and content explanation
This article delves into the next evolution of Azure infrastructure from a technical perspective. We'll explain how it works and its limitations, focusing on cooling innovations, bare metal servers, and storage improvements. First, take a look at the overview image.
Azure's cooling innovation involves the introduction of a liquid cooling system, which improves thermal conductivity compared to traditional air cooling. This system efficiently removes heat by circulating coolant directly over the server chips. While the initial cost is high, it can reduce energy consumption by 30-40% over the long term.
Next, bare metal servers provide direct access to physical servers, eliminating the virtualization layer. Technically, they eliminate hypervisor overhead and deliver native performance. However, they require enhanced security, so we recommend combining them with Azure's Trusted Launch feature.
In terms of storage improvements, NVMe-based high-speed storage has been enhanced, increasing IOPS by several times. The mechanism achieves low latency through optimized parallel processing and caching. For technical comparison, the table below shows the conventional vs. new elements.
| Item | Traditional Azure infrastructure | New features (2025 and beyond) | technical comparison |
|---|---|---|---|
| cooling system | Mainly air-cooled, fan-dependent | Liquid cooling, immersion option | Heat removal efficiency improved by 2-3 times, but maintenance became more complicated. |
| Server Type | VM-centric, with virtualization overhead | Bare metal server support | 0% performance overhead, custom BIOS settings possible, but increased security controls |
| Storage Performance | HDD/SSD mixed, IOPS limited | All NVMe, AI-optimized cache | Throughput is more than four times faster and latency is halved. However, the cost/GB is high. |
| Overall constraint | High energy consumption, limited scalability | Sustainable design, easy to scale out | Although initial investment is higher, it offers advantages in terms of TCO (Total Cost of Ownership) |
As you can see from this table, the new elements are designed to prioritize performance while minimizing constraints. As an engineer, the key point when implementing this using Azure CLI or ARM templates is to consider zone resilience.
Impact and use cases
These innovations have a significant impact on engineers at a practical level. For example, in AI workloads, liquid cooling can extend the continuous operating time of GPU clusters and shorten training times. In one real-world example, improved cooling efficiency in large-scale ML model development reduced energy costs by 25%.
Bare metal servers are powerful tools for high-performance computing (HPC). Running native applications without virtualization improves the accuracy of simulations. Storage improvements are also used in big data analytics, doubling query speeds for tools like Apache Spark.
The technical impact is reduced system downtime and improved SLA (Service Level Agreement), which are comparatively differentiating points from AWS and GCP, and are reasons to choose Azure for hybrid cloud design.
Action Guide
As an engineer, what should you do next? First, check the preview of bare metal instances in the Azure portal and create a test environment. You can start with the command az vm create --bare-metal.
For cooling, optimize your data center location selection. Deploy in an energy-efficient region. For storage, use Azure Storage Explorer to explore NVMe options and measure IOPS.
Additionally, we've customized an ARM template based on the Azure sample repository on GitHub, taking into account constraints and recommending actions to strengthen security groups, which you can immediately incorporate into your projects.
Future prospects and risks
The future of Azure infrastructure is bright, with quantum cooling and AI-driven automatic optimization expected by 2026. This will standardize global-scale AI applications and shift engineers' work to more creative roles.
However, there are still risks, such as the risk of cooling system leaks and security vulnerabilities in bare metal. Downtime during storage data migration is also a concern. To mitigate these risks fairly, it is important to utilize Azure monitoring tools and conduct regular risk assessments.
Overall, the benefits of innovation are great, but a balanced approach is needed without ignoring the constraints.
My Feelings, Then and Now
The next step in Azure infrastructure will solve technical challenges with innovations in cooling, bare metal, and storage. Understanding and leveraging these will improve system efficiency and reliability. Get a deep technical perspective on the future of Azure.
