Question

Difficulty: Very hardAzure Arc

A multinational enterprise operates a hybrid and multi-cloud environment consisting of Kubernetes clusters running in an on-premises datacenter, virtual machines hosted in Amazon Web Services (AWS), and database servers on physical hardware in a private datacenter. The IT department wants to apply a single governance model using Azure Policy and centrally monitor system health using Azure Monitor. They must achieve this without migrating any of the workloads to Azure and without purchasing new dedicated hardware. Which of the following solutions should they implement?

  1. Implement Azure Arc to register the external virtual machines and Kubernetes clusters, allowing Azure Resource Manager to manage them as projected Azure resources.Answer
  2. B
    Deploy Azure Stack Hub in both the private datacenter and the AWS environment to host the workloads within an Azure-consistent hybrid cloud.
  3. C
    Migrate all external virtual machines and Kubernetes clusters to Azure virtual networks, as Azure Policy and Azure Monitor can only manage resources residing natively within the Azure public cloud.
  4. D
    Establish Azure ExpressRoute connections to all environments, which automatically projects external workloads into Azure Policy without requiring additional host agents.

Answer

The enterprise should implement Azure Arc to register their external virtual machines and Kubernetes clusters, allowing them to be managed and monitored through Azure Resource Manager without migration or hardware purchases.
Implementing Azure Arc is the correct solution because it is designed to project external resources, such as on-premises physical servers, virtual machines, and Kubernetes clusters in other clouds, into the Azure Resource Manager (ARM) control plane. This enables the use of Azure Policy and Azure Monitor on these external resources without migrating the workloads or purchasing dedicated hardware.

Step-by-Step Solution

1
Identify the requirement to manage and monitor virtual machines and Kubernetes clusters residing outside of Azure (on-premises and AWS) without migration or new hardware.
Limits options to hybrid/multi-cloud management tools that do not require workload migration or local hardware deployments.
Understanding the environmental constraints helps eliminate migration-based or hardware-centric solutions.
2
Evaluate Azure Arc's capabilities regarding non-Azure resources.
Azure Arc projects non-Azure servers and Kubernetes clusters into Azure Resource Manager (ARM) as if they were native Azure resources.
This allows native Azure tools like Azure Policy and Azure Monitor to be applied to these external resources directly.
3
Select the solution that projects these resources into the ARM control plane using agents.
Implementing Azure Arc is selected as the correct management projection solution.
It fulfills all governance and monitoring requirements without violating the constraints of no migration and no new hardware.
