Suitable for development, analytics, disaster recovery scenarios, and testing of large datasets, these clones can be refreshed quickly from the latest snapshots and remain temporary for up to one month, consuming capacity only for incremental changes. The capability accelerates workflows, improves quality and resilience, and lowers costs by avoiding full-copy storage and reducing operational overhead, and is available in all Azure NetApp Files supported regions.

Entra ID and RBAC support for supplemental Azure Storage APIs

Support for Entra ID (OAuth 2.0) and Azure RBAC is now generally available for the following Azure Storage operations: Get Account Information, Get/Set Container ACL, Get/Set Queue ACL, and Get/Set Table ACL. With this change, REST responses for unauthorized access have been aligned with other OAuth-enabled Storage APIs: calls made with OAuth that lack required permissions now return 403 (Forbidden) instead of the previous 404, while anonymous requests for a bearer challenge return 401 (Unauthorized). For example, GetAccountInformation requires the RBAC action Microsoft.Storage/storageAccounts/blobServices/getInfo/action. Applications that depend on the old 404 behavior should be updated to handle both 403 and 404 responses, as SDKs will not automatically adjust this behavior.

Networking

Private Subnet

Azure announces the general availability of the private subnet functionality. Traditionally, virtual machines created in a virtual network without explicit outbound configuration were assigned a default outbound public IP address. These implicit IPs presented security challenges and lacked association with subscriptions, making them unreliable and difficult to manage. With the private subnet feature, any new subnet defaults to having “default outbound access” set to false, thus eliminating implicit outbound connectivity and promoting Azure’s “secure by default” principle. Users must now explicitly configure outbound access using services such as NAT Gateway or Public IP addresses. Starting September 30th, 2025, all new virtual networks will adopt this default behavior, although existing networks and older API versions will remain unaffected.

Azure Traffic Manager SLA Increased to 100%
