Synchronous replication of data across zones in a region enables disks to tolerate outages due to natural disaster or hardware failures. You can maximize the availability of your virtual machines without the replication of application-level data, which in some cases might not even be supported, e.g for legacy applications and old industry-specific proprietary software. If a VM becomes unavailable, you can mount the disk to a VM in a different zone. The ZRS option can also be used to share disks to improve the availability of clustered distributed applications.
Application Gateway Mutual Authentication is now in public preview
Frontend mutual authentication is now supported by Azure Application Gateway. Additional to the client authenticating Application Gateway, Application Gateway can now also authenticate the client. Multiple client Certificate Authority (CA) certificate chains for Application Gateway can be uploaded and used for client authentication.
Enable mutual authentication at a per listener level on your gateway or choose to use server variables, for passing client authentication information to the backends. This enables scenarios where the client needs to authenticate Application Gateway and vice versa.
Public preview – Azure Arc: Run Event Grid on Kubernetes in Azure or anywhere
With Azure Arc, it is now possible to run Azure Event Grid on AKS or anywhere else. This preview feature combines a fully managed Event Grid on Azure and the control of Kubernetes. Choose if you want to run Event Grid, or deploy on your AKS or another Kubernetes cluster connected via Azure Arc. Regardless of the cluster running on-premises, at the edge or in a cloud.
Event Grid provides customers with a single service for managing routing of all events from any source to any destination. This vastly simplifies event-based application development. During preview, Event Grid on Kubernetes (using Azure Arc) will be available in:
- West Europe
- US East

New Durable Functions storage provider options (public preview)
By default, Durable Functions use Azure Storage as its storage provider. With this public preview, Durable Functions will now support two additional storage providers:
- Netherite storage provider – powered by Azure Event Hubs and Azure Page Blobs. Using the faster database technology from Microsoft Research, it supports significantly higher throughput than other Durable Functions storage providers and is at the same time more cost-effective for high-throughput workloads.
- Microsoft SQL Server provider – Run Durable Functions wherever SQL Server is available. This includes on-premises environments as well as Kubernetes. Organizations can leverage existing investments in SQL Server, management expertise, and strategies for e.g. failover, compliance, or backup/restore.
General availability: PowerShell support in Durable Functions
Durable Functions now supports PowerShell. Using familiar language constructs in PowerShell 7, it is now possible to orchestrate complex automation workflows in Azure Functions. This includes common scenarios such as complex Azure Resource deployments involving sequential and/or parallel steps. Durable Functions provide built-in HTTP endpoints for monitoring the progress of long-running workflows.
For getting started check out this quickstart.
Public preview: Azure Security Center integration with GitHub Actions
The integration of Azure Security Center with GitHub Actions enables you to integrate security and compliance into the early stages of your software development lifecycle. This integration offers visibility in CI/CD pipeline and registry container security scans with Azure Security Center. Improve remediation time and strengthen your cloud security posture by identifying issues faster with the help of end-to-end traceability.
Additionally, Microsoft is introducing a new container scanning action. This action scans container images for vulnerabilities before images are pushed into Azure container registries.
Azure Kubernetes Service News
There were also a ton of news around Azure Kubernetes Service:
Cluster auto-upgrade now respects planned maintenance windows (public preview)
Scheduled weekly maintenance windows for updates allow minimizing workload impact. Planned maintenance windows in Azure Kubernetes Service can now be used in combination with cluster auto-upgrade. Automatic upgrades can be scheduled during a specific time slot that was allocated.
Public preview: AKS support for Secrets Store Container Storage Interface
AKS support for Secrets Store CSI is now in public preview. The Container Storage Interface (CSI) driver for secret storage allows you to mount multiple secrets, keys, and certificates stored in your secret storage into your Pod as a CSI volume. By attaching a volume in this way, secure access to secrets is significantly simplified because the data can be accessed through the container’s file system.
Public preview: AKS support for containerd for Windows server containers
Containerd is the industry-standard container runtime. Utilizing containerd increases both the speed of pod creation and stability. Containerd is available on Azure Kubernetes Service (AKS) with Kubernetes version 1.20 and higher.

General availability: Azure RBAC for Kubernetes Authorization in AKS
With Azure’s role-based access control (RBAC) for Kubernetes authorization, you can gain consistent governance and access control across Azure and AKS resources. When this integration is enabled, you can use Azure Active Directory (AAD) users, groups, or service principals natively as entities in Kubernetes RBAC.
Azure Cosmos DB updates
As with AKS, there were also quite a few updates around Azure Cosmos DB:
Partial document update for Azure Cosmos DB in private preview
Partial document update for Azure Cosmos DB now allows you to perform path-level updates for specific fields/properties within a single document without having to perform a full read-replace operation on the document. With this update, there are significant productivity benefits for developers by removing the need to perform explicit document reads, OCC checks, and document replacement operations on the client-side. This provides programming flexibility by allowing conditional partial document updates based on a predicate filter as well as supporting modes such as bulk, transactional batch, and multiple patch operations.
