Key features of Azure Arc:
Extend Azure management and security to any infrastructure
Hundreds of millions of Azure resources are organized, governed and secured daily by customers using Azure management. Azure Arc extends these proven Azure management capabilities to Linux and Windows servers, as well as Kubernetes clusters on any infrastructure across on-premises, multi-cloud and edge. Customers can now have a consistent and unified approach to managing different environments using robust, established capabilities such as Azure Resource Manager, Microsoft Azure Cloud Shell, Azure portal, API, and Microsoft Azure Policy. With Azure Arc, developers can build containerized apps with the tools of their choice and IT teams can ensure that the apps are deployed, configured, and managed uniformly using GitOps-based configuration management. Finally, Azure Arc makes it easier to implement cloud security across environments with centralized role-based access control and security policies. Learn more about Azure Arc.
Run Azure data services anywhere
With Azure Arc, customers can now realize the benefits of cloud innovation, including always up-to-date data capabilities, deployment in seconds (rather than hours), and dynamic scalability on any infrastructure. Customers now have the flexibility to deploy Azure SQL Database and Azure Database for PostgreSQL Hyperscale where they need it, on any Kubernetes cluster. From the Azure portal, customers get a unified and consistent view of all their Azure data services running across on-premises and clouds and can apply consistent policy, security and governance of data across environments. Customers can get limitless scale by seamlessly spinning up additional Kubernetes clusters in Azure Kubernetes Service (AKS) if they run out of capacity on-premises.

Expanded Azure Stack offerings for any edge
Azure Stack Edge is a managed AI-enabled edge appliance that brings compute, storage and intelligence to any edge. Customers will be able to take advantage of new capabilities including Virtual Machine support, a GPU based form factor, high availability with multiple nodes, and multi-access edge compute (MEC).
