Overview of Azure Arc

Azure Arc is Microsoft’s hybrid and multi-cloud management solution that expands Azure’s management capabilities beyond its native environment, allowing you to manage resources across on-premises, multi-cloud, and edge environments from a single control plane. Azure Arc enables you to centralize governance, operations, and security, ensuring consistency and compliance across many infrastructures.

Key Features of Azure Arc

• Consistent Inventory and Governance: Use consistent inventory, management, governance, and security throughout your environment to ensure control over both Azure and non-Azure resources.
• VM Extension Management: Set up Azure VM extensions to monitor, secure, and upgrade your on-premises and cloud-based servers with Azure management services, making server administration easier.
• Kubernetes Cluster Management: Scale Kubernetes clusters to ensure seamless operations for containerized apps across several environments.
• GitOps Integration: Use GitOps to distribute configurations to one or more Kubernetes clusters using Git repositories, allowing for automated and version-controlled deployments.
• Zero-Touch Compliance: Using Azure Policy, enforce compliance and configuration policies for Kubernetes clusters, assuring consistency without requiring user intervention.
• Azure Data Services Anywhere: You can run Azure SQL Managed Instance and Azure Database for PostgreSQL on any Kubernetes environment, including elastic scaling, automated upgrades, and built-in security, even if you don’t have continuous Azure access.
• Hybrid VM Management: Manage virtual machines on Azure Stack HCI and on-premises environments using VMware vCenter or System Centre Virtual Machine Manager (SCVMM). Using Azure role-based access control (RBAC), teams can self-serve VM operations on demand.
• Unified Management Experience: Whether using the Azure portal, CLI, PowerShell, or REST API, you’ll have a uniform experience across all of your Azure Arc-enabled services, making hybrid and multi-cloud management easier.
• Custom Locations for Azure Services: Create custom locations on top of your Azure Arc-enabled Kubernetes clusters to deploy Azure service instances, including Azure App Services (Web, Functions, Logic Apps) and Event Grid on Kubernetes.
