Title: Public Preview: Azure Monitor Logs mirroring into Microsoft Fabric
Link: Azure Update Details

Background and Purpose of the Update

This update introduces the public preview of a feature that enables telemetry data from Azure Monitor Log Analytics workspaces to be shared directly into Microsoft Fabric. The primary goal is to enhance observability by making log data natively available within Microsoft Fabric’s OneLake storage, leveraging the open Delta Parquet format. This integration aims to streamline data accessibility for analytics and reporting without the need for data duplication or complex data movement processes.

Specific Features and Detailed Changes

Log Mirroring: Telemetry from Azure Monitor Log Analytics workspaces can now be mirrored into Microsoft Fabric.
Data Format: The mirrored data is stored in OneLake as Delta Parquet files, an open and widely supported format optimized for analytics workloads.
Near Real-Time Availability: The solution provides near real-time access to observability data within Microsoft Fabric.
No Data Duplication: The mirroring process does not duplicate data, ensuring efficient storage utilization and consistency.

Technical Mechanisms and Implementation Methods

Data Flow: Azure Monitor Log Analytics workspaces act as the source of telemetry data. The mirroring mechanism streams this data directly into OneLake, Microsoft Fabric’s unified data lake.
Storage Format: Data is written in the Delta Parquet format, which supports ACID transactions and efficient querying, making it suitable for large-scale analytics and machine learning workloads.
Integration Layer: The mirroring is managed as a native capability, eliminating the need for custom ETL pipelines or third-party connectors.
Availability: Data is made available in near real-time, supporting timely analytics and operational insights.

Use Cases and Application Scenarios

Unified Analytics: Organizations can leverage Microsoft Fabric’s analytics tools to query and analyze Azure Monitor logs alongside other enterprise data sources.
Advanced Reporting: IT teams can build comprehensive dashboards and reports using Fabric’s analytics and visualization capabilities, with direct access to observability data.
Compliance and Auditing: Storing logs in an open format within OneLake facilitates long-term retention, compliance auditing, and integration with governance solutions.
Machine Learning: Data scientists can use the Delta Parquet logs for advanced analytics and machine learning scenarios within Microsoft Fabric.

Important Considerations and Limitations

Public Preview: This feature is currently in public preview, which may imply limited support and potential changes before general availability.
Data Scope: The update applies to telemetry data from Azure Monitor Log Analytics workspaces only.
Performance and Latency: While near real-time access is provided, specific latency guarantees are not detailed in the update.
Format Compatibility: Consumers of the mirrored data must support the Delta Parquet format for downstream processing.

Azure Monitor: Acts as the source of log telemetry data.
Microsoft Fabric: Receives and stores the mirrored data in OneLake, enabling analytics and reporting.
OneLake: Serves as the unified storage layer for all mirrored logs.
Delta Parquet: Ensures compatibility with a broad ecosystem of analytics and data science tools.

Summary:
Azure Monitor Logs can now be mirrored into Microsoft Fabric’s OneLake as Delta Parquet files, providing near real-time, open-format access to observability data for analytics and reporting, without data duplication, in public preview.

2. Generally Available: Azure Sphere OS version 26.09 is now available for evaluation

Published: July 29, 2026 18:50:00 UTC Link: Generally Available: Azure Sphere OS version 26.09 is now available for evaluation

Azure Update Report: Azure Sphere OS version 26.09 RC1 Evaluation Release

Background and Purpose of the Update
Azure Sphere is Microsoft’s end-to-end platform for securing IoT devices, combining a secure microcontroller, a custom Linux-based OS, and cloud-based security services. The release of Azure Sphere OS version 26.09 RC1 to the Retail Eval feed marks a significant step in the ongoing maintenance and enhancement of the platform’s security and reliability. The primary purpose of this update is to deliver a major upgrade to the underlying Linux kernel, aligning with Microsoft’s long-term support strategy for Azure Sphere.

Specific Features and Detailed Changes
Version 26.09 RC1 does not introduce customer-facing changes or new features. The main technical change is the substantial update to the Linux kernel version at the core of Azure Sphere OS. This kernel upgrade is foundational, providing improved security, stability, and performance benefits inherent to newer kernel versions. No modifications to APIs, user interfaces, or device management features are included in this release.

Technical Mechanisms and Implementation Methods
The update is distributed through the Retail Eval feed, which is intended for evaluation and testing by device manufacturers and solution integrators prior to broad deployment. The kernel upgrade process involves replacing the previous kernel version with the new one, ensuring compatibility with existing Azure Sphere hardware and software stacks. The Retail Eval feed allows IT professionals to validate device functionality, assess system stability, and ensure that custom applications and integrations continue to operate as expected with the updated kernel.

Use Cases and Application Scenarios
This release is particularly relevant for organizations managing fleets of Azure Sphere devices in production environments. IT professionals and device manufacturers should use the Retail Eval feed to test the new OS version on their devices, confirming that all critical workloads, security policies, and custom applications remain functional. Typical scenarios include pre-deployment validation, regression testing, and compatibility checks for IoT solutions that rely on Azure Sphere’s secure platform.

Important Considerations and Limitations

The 26.09 RC1 release is for evaluation only and is not intended for production deployment until full validation is complete.
There are no customer-facing changes; the update is strictly a kernel upgrade.
Device manufacturers and solution integrators must thoroughly test their devices and applications against this OS version to ensure compatibility and stability.
The Retail Eval feed provides a preview window before the update is pushed to the broader Retail feed, allowing for proactive issue identification and remediation.

Integration with Related Azure Services
Azure Sphere OS is tightly integrated with Azure Sphere Security Service, which delivers ongoing security updates, device authentication, and application deployment. The kernel upgrade in version 26.09 RC1 ensures continued compatibility and support for these cloud-based services. No changes to integration points or service APIs are introduced in this release, but IT professionals should verify that device connectivity and security features remain unaffected during evaluation.

Summary Sentence
Azure Sphere OS version 26.09 RC1, now available in the Retail Eval feed, delivers a major Linux kernel upgrade for evaluation, with no customer-facing changes, supporting long-term security and stability for Azure Sphere devices.
