Azure Update - 26th September 2025

Key insights

• Azure Update (26 Sep 2025)
  Summary of a recent YouTube update about Azure changes and retirements; this is a third‑party recap, not the original video author.
• Service retirements and actions
  Microsoft announced key retirements — notably the Basic SKU public IPs (final retirement by Sep 30, 2025) and several VM/feature retirements (NVv3, ADE, App Service on Arc). Plan upgrades and test migrations now to avoid disruption.
• AKS and container management
  AKS Fleet Manager auto-upgrade and AKS Automatic simplify cluster updates and scaling, and the AKS insights blade moved in the portal. Enable staged upgrades and verify workloads on test clusters first.
• Storage, backup, and database updates
  Azure Container Storage v2 reached GA with NVMe boosts and improved features; vaulted backups for Azure Files Premium and ANF flexible service levels arrived. PostgreSQL and MySQL discovery/backup improvements and PostgreSQL 18 support require review for compatibility and backup plans.
• Networking and security enhancements
  Dedicated backend connections for Application Gateway reached GA, App Gateway added server‑sent events support, and Azure Front Door added signed request capabilities. Upgrade Basic public IPs to Standard SKU to meet new security and availability expectations.
• Developer tools, certifications, and marketplace
  Azure Functions moved to .NET 10, GitHub Copilot features surfaced for Azure Boards, and the Microsoft Marketplace got a refresh. Update training and AZ‑900/AZ‑104 study plans to include these changes and test CI/CD pipelines against new runtimes.

Introduction: Video Overview and Context

On September 26, 2025, the YouTube channel of John Savill's [MVP] published a concise update covering a range of Azure announcements and service changes. The video summarized new features, important retirements, and practical implications for cloud teams and certification candidates. Consequently, this article distills those highlights into a clear news story while noting operational tradeoffs and migration challenges. Moreover, readers will find guidance on where to focus planning effort in the weeks ahead.

Major Feature Announcements

First, the video highlighted several feature releases aimed at performance and developer productivity. For example, Azure Container Storage v2.0 reached general availability with NVMe performance improvements and a removal of some service fees, which may reduce costs for containerized workloads while increasing I/O capacity. In addition, the update noted that Azure App Service now supports BYOL for JBoss EAP, enabling customers to reuse existing licenses and potentially lower long-term software expenses.

Furthermore, platform management advances were emphasized, including AKS Automatic for simplified Kubernetes lifecycle operations and the upgrade of Azure Functions to .NET 10 for better runtime performance. Also, data security received attention through PostgreSQL Confidential compute protections to managed PostgreSQL, which brings confidential compute protections to managed PostgreSQL, aligning with stricter compliance requirements. Together these changes aim to streamline operations while strengthening security for many common cloud workloads.

Retirements and Migration Challenges

However, the video also warned about several retirements that require immediate planning, most notably the phase-out of the Basic SKU for public IP addresses, with a retirement deadline of September 30, 2025. This change forces teams to upgrade to the Standard SKU, and yet the presenter cautioned that official upgrade paths, particularly from legacy classic configurations, remain unclear, so careful testing and vendor support consultation are prudent steps. Likewise, the announcement included plans to retire the Azure Databricks Standard tier and to phase out Azure Linux 2.0 on AKS, prompting architecture reviews to avoid unsupported configurations.

These retirements introduce tradeoffs: while moving to modern SKUs and supported tiers improves security and feature access, migrations can create downtime risk, require IP renumbering, or involve compatibility checks for third-party appliances. Thus, teams must balance the urgency of compliance with the operational costs of migration, and should prioritize high-impact services while scheduling noncritical transitions during maintenance windows. In short, planning and testing will determine whether the migration delivers net benefit without unexpected disruption.

Operational Impact and Certification Relevance

Operationally, the video connected feature changes to real-world admin tasks, explaining how AKS Automatic and the Azure SQL hub experience can reduce manual effort for routine management. At the same time, enhancements like dedicated backend connections in Application Gateway and stricter IP SKUs tighten network security, which means administrators must update runbooks and monitoring to reflect tightened policies. Moreover, Microsoft’s updates to runtimes and services suggest teams should revise deployment pipelines to incorporate new defaults and supported runtimes.

From a certification standpoint, John Savill pointed out that updates affect exam topics for AZ-900 and AZ-104, including confidential computing, container orchestration, and networking changes. Therefore, candidates and trainers should include these changes in study plans and lab exercises to remain current. Nevertheless, the pace of change also creates a challenge for educational content creators who must refresh materials rapidly while ensuring accuracy.

Tradeoffs, Recommendations, and Next Steps

Balancing performance, cost, and risk emerges as the central theme of the video, and tradeoffs must be evaluated on a case-by-case basis. For example, adopting Azure Container Storage v2.0 may boost throughput and lower fees, but it could require refactoring storage drivers or validating application assumptions about latency. Similarly, upgrading IP SKUs enhances security and features, yet it can be disruptive if migration planning is incomplete.

Accordingly, the presenter recommended inventorying affected services, prioritizing those that touch critical paths, and creating rollback plans before broad change windows. In addition, teams should use staging environments to validate behavior under the new SKUs and runtimes, and engage support channels early when migration paths are unclear. Finally, while automation helps reduce repetitive effort, a measured rollout with monitoring and alerting remains essential to detect regressions quickly.

Conclusion

In summary, the YouTube update from John Savill's [MVP] delivered a compact briefing on several meaningful Azure changes, blending promising new capabilities with important retirements that demand attention. While new features promise better performance, security, and developer productivity, the retirements and SKU changes present concrete migration work and operational tradeoffs. Therefore, cloud teams and certification candidates alike should update plans and learning paths, prioritize testing, and move deliberately to balance innovation with reliability.
