Public Preview: Evaluate feature rollouts with Azure App Configuration Scorecards

Public Preview: Evaluate feature rollouts with Azure App Configuration Scorecards
Azure App Configuration now supports a scorecards capability in public preview. Scorecards provide a telemetry-driven view of how feature flag variants are performing in production, helping teams identify measurable changes after a rollout without manually comparing telemetry across dashboards.

Built on Azure App Configuration Feature Management and Application Insights telemetry, scorecards help teams use production signals to evaluate rollout impact and guide next steps. Learn how scorecards can help evaluate feature rollouts.

With scorecards, teams can:

• Compare feature variants against key performance indicators
• Detect potential issues introduced by new or updated feature behavior
• Evaluate adoption and usage of features
• Use telemetry insights to support rollout, optimization, and deprecation decisions

Generally Available: Azure NetApp Files cache volumes
Azure NetApp Files cache volumes is now Generally Available. Azure NetApp Files now support cache volumes, which are cloud-based caches of an external origin volume, containing only the most actively accessed data on the volume. This brings data and files closer to the user for faster throughput with a smaller footprint. Azure NetApp Files cache volumes simplify file distribution, reduces WAN latency, and lowers WAN/ExpressRoute bandwidth costs.

Generally Available: Network Watcher rule impact analyser
Azure Network Watcher rule impact analyzer is now generally available, enabling you to assess the potential impact of your network security group (NSG) or security admin rule changes on live network traffic before applying them.

With this capability, you can evaluate how proposed NSG or network manager rule modifications would affect your existing traffic patterns, helping you fine-tune configurations, avoid unintended disruptions, and deploy changes with confidence.

This feature is accessible through the Azure portal and leverages Azure Network Watcher traffic analytics and virtual network flow logs to deliver data-driven visibility into how NSG or network manager rule updates could influence your current network behavior.

Generally Available: Azure Virtual Network updates – default limits increased for NSGs and route tables

Azure Virtual Network has increased the default platform limits for network security groups (NSGs) and route tables. The new defaults are now 2,000 security rules per NSG, 6,000 addresses or ports per NSG rule, 1,000 routes per route table, and 600 route tables per subscription.

This update enables customers to:

• Scale security policies with confidence: Enterprises managing hundreds of application tiers and subnets can define more granular NSG rules without hitting default ceilings or opening support cases.
• Support larger routing topologies out of the box: Customers with complex hub-and-spoke architectures can configure more routes per route table and deploy more route tables per subscription.

Generally Available: Mock runs for Azure Storage Actions – Validate before you execute

Azure Storage Actions, our fully managed platform that transforms how organizations automate data management tasks for Azure Blob and Data Lake Storage, now supports mock runs - a new way to simulate task execution at full scale without modifying any data.

Mock runs enable you to validate your task conditions by scanning and evaluating billions of objects against your storage accounts, generating a detailed report showing exactly which blobs would be affected and what operations would be performed without making any changes. Mock runs validate across every blob in scope, giving you complete confidence before committing to irreversible blob operations. Combining full-scale validation with detailed CSV reporting, mock runs eliminate guesswork and drive safe, predictable automation.

Supported use cases include validating retention and expiry policies, previewing cost optimization through down tiering or up tiering, confirming compliance enforcement such as legal holds and immutability, and verifying large-scale cleanup or tagging operations before execution. You can create a mock run by selecting it as the trigger type when creating a storage task assignment, review the results, and then seamlessly transition the assignment to a real run without recreating it.
