📖 What is Azure Arc?
Azure Arc enables you to manage, govern, and secure resources across on-premises, multicloud, and edge environments from a single control plane in Azure. It extends Azure services and policies to resources outside of Azure, providing consistent management and compliance across hybrid and distributed infrastructures.
"Azure Arc is not about *moving* workloads to Azure; it’s about *managing* them from Azure. Focus on the benefits of centralized governance and policy enforcement. Understand the key components: Arc-enabled servers and Azure Policy."
📚 Certification: Microsoft Azure Fundamentals (AZ-900)
🔑 What are the Key Concepts of Azure Arc?
- ▸ Azure Arc extends Azure Resource Manager to manage resources anywhere – on-premises, other clouds, and edge locations.
- ▸ Arc-enabled servers allow you to onboard and manage servers without requiring a full Azure VM deployment.
- ▸ Azure Policy can be applied consistently across all Arc-enabled resources, ensuring compliance and governance.
- ▸ Centralized inventory and monitoring are key benefits, providing a single pane of glass for all your resources.
- ▸ It doesn’t migrate workloads *to* Azure, but manages them *from* Azure, maintaining existing infrastructure.
🎯 How does Azure Arc appear on the AZ-900 Exam?
You may be asked to identify the Azure service that allows a company to apply Azure Policies to servers running in their on-premises datacenter.
A scenario might describe a company with resources in AWS and Azure; expect questions about how Azure Arc can provide unified governance across both environments.
Expect questions about the benefits of using Azure Arc for managing a large fleet of servers distributed across multiple locations, focusing on centralized management.
❓ Frequently Asked Questions
What types of resources can be managed with Azure Arc?
Azure Arc supports servers (Windows and Linux), Kubernetes clusters, and Azure Data Services deployed outside of Azure. It’s expanding to include more resource types over time.
Does Azure Arc require a constant connection to the Azure cloud?
While Arc benefits from connectivity, it can operate in disconnected or intermittently connected scenarios. It uses a proxy to communicate with Azure when a direct connection isn’t available.
How does Azure Arc relate to Azure Stack?
Azure Stack is a fully managed Azure service deployed in your datacenter. Azure Arc manages existing infrastructure *as is*, while Azure Stack *is* Azure running on your hardware.
