This blog post series highlights the key announcements and major updates related to Azure Infrastructure as a Service (IaaS) and Azure Local, as officially released by Microsoft in the past two weeks.
Azure
General
Availability of Microsoft Azure and related services
Microsoft has announced several generally available updates related to the expansion of Azure infrastructure and storage services. First, Microsoft has opened its new cloud region in Denmark, Denmark East, to support digital transformation and AI innovation for customers in the country. This new region provides local, secure cloud infrastructure with support for data residency, low-latency access, and access to advanced cloud and AI services. In addition, Azure Premium SSD v2 is now available in US Gov Arizona, a region without Availability Zones, extending access to this next-generation general-purpose block storage option for Azure virtual machines in government environments. Azure Premium SSD v2 offers sub-millisecond latency and strong price-performance characteristics for IO-intensive workloads such as SQL Server, Oracle, MariaDB, SAP, Cassandra, MongoDB, big data and analytics platforms, and gaming workloads running on virtual machines or stateful containers. Azure Premium SSD v2 is also now available in South India, further expanding regional access to this storage option for enterprise production workloads that require high performance and cost efficiency.
Compute
Ephemeral OS Disk with full caching for VM/VMSS (preview)
Ephemeral OS Disk with full caching is now available in public preview for Azure Virtual Machines and Virtual Machine Scale Sets, delivering significantly faster and more reliable OS disk performance for supported workloads. This capability works by caching the entire OS disk image on local VM storage, including cache disk, resource disk, or NVMe disk, which results in improved I/O performance, consistently low latency, and greater resilience in scenarios involving remote storage disruptions. The feature is especially beneficial for stateless and I/O-sensitive workloads such as AI applications, quorum-based databases, data analytics platforms, and large-scale stateless services running on General Purpose VM families. It is currently available on most General Purpose VM SKUs, excluding 2-core and 4-core virtual machines, in Central US. Customers can enable it by setting the
Networking
Unlock client-side configuration at scale with Azure App Configuration and Azure Front Door (preview)
Azure App Configuration, integrated with Azure Front Door, is now available in public preview and enables organizations to deliver dynamic configuration directly to client-side applications securely and at CDN scale. This new capability brings greater flexibility to modern application architectures and is particularly relevant for AI-powered and agentic client applications. It supports a wide range of client experiences, including Single Page Applications built with frameworks such as React, Vue, Angular, and Next.js, as well as mobile and desktop applications developed with .NET MAUI, browser-based JavaScript components, embedded widgets, and other web applications capable of running JavaScript. With this integration, customers can centrally manage feature flags and configuration settings and propagate updates to browsers and mobile apps in real time without redeploying applications. Azure Front Door provides low-latency delivery for large global audiences, while the design ensures that secrets are not exposed to clients, as only scoped configuration values are delivered through managed identity. This built-in approach also simplifies application architecture by removing the need for custom proxy layers.
Storage
Azure Data Box enhancements
Azure Data Box now includes two generally available enhancements designed to improve compliance, transparency, and data transfer flexibility. First, Azure Data Box automatically generates a downloadable Secure Erasure Certificate for every completed order, verifying that all data on the device has been securely erased in accordance with NIST 800-88 Revision 2 standards. The certificate is produced as part of the standard cleanup process and is available directly through the Azure portal, reducing audit complexity, eliminating the need for manual validation, and simplifying compliance requirements for organizations working with sensitive data, including those in government, law enforcement, and financial services. In addition, Azure Data Box now supports data ingestion into Azure Files Provisioned v2 storage accounts. This allows customers to transfer data directly into a storage model where capacity, IOPS, and throughput are provisioned independently, offering greater flexibility and cost control for file share workloads across most public Azure regions.
Azure NetApp Files storage with cool access enhancement (preview)
The cool access enhancement for Azure NetApp Files storage is now in public preview and introduces an updated Quality of Service (QoS) behavior for Premium and Ultra service levels. This enhancement improves the way Azure NetApp Files balances performance and cost for environments that combine hot and cool data workloads. As data moves to cool storage, throughput is automatically adjusted to preserve hot-tier performance while still allowing customers to take advantage of cool access at scale. The capability continuously optimizes pool and volume throughput according to changing cool access patterns, delivering a more seamless operational experience and reducing the need for manual tuning. As a result, organizations can better align storage performance with workload demand while improving cost efficiency for mixed-use datasets.
Conclusion
Over the past two weeks, Microsoft has introduced a slew of updates and announcements pertaining to Azure Infrastructure as a Service (IaaS) and Azure Local. These developments underscore the tech giant’s unwavering commitment to enhancing its cloud offerings and adapting to the ever-evolving needs of businesses and developers. Users of Azure can anticipate improved functionalities, streamlined services, and enriched features as a result of these changes. Stay tuned for more insights as I continue to monitor and report on Azure’s progression in the cloud sphere.
