Overview of Arc-enabled System Center Virtual Machine Manager

Azure Arc-enabled System Center Virtual Machine Manager (SCVMM) empowers System Center customers to connect their VMM environment to Azure and perform VM self-service operations from Azure portal. Azure Arc-enabled SCVMM extends the Azure control plane to SCVMM managed infrastructure, enabling the use of Azure security, governance, and management capabilities consistently across System Center managed estate and Azure.

Azure Arc-enabled System Center Virtual Machine Manager also allows you to manage your hybrid environment consistently and perform self-service VM operations through Azure portal. For Microsoft Azure Pack customers, this solution is intended as an alternative to perform VM self-service operations.

Arc-enabled System Center VMM allows you to:

  • Perform various VM lifecycle operations such as start, stop, pause, and delete VMs on SCVMM managed VMs directly from Azure.
  • Empower developers and application teams to self-serve VM operations on demand using Azure role-based access control (RBAC).
  • Browse your VMM resources (VMs, templates, VM networks, and storage) in Azure, providing you with a single pane view for your infrastructure across both environments.
  • Discover and onboard existing SCVMM managed VMs to Azure.
  • Install the Arc-connected machine agents at scale on SCVMM VMs to govern, protect, configure, and monitor them.

Onboard resources to Azure management at scale

Azure services such as Microsoft Defender for Cloud, Azure Monitor, Azure Update Manager, and Azure Policy provide a rich set of capabilities to secure, monitor, patch, and govern off-Azure resources via Arc.

By using Arc-enabled SCVMM's capabilities to discover your SCVMM managed estate and install the Arc agent at scale, you can simplify onboarding your entire System Center estate to these services.

How does it work?

To Arc-enable a System Center VMM management server, deploy Azure Arc resource bridge in the VMM environment. Arc resource bridge is a virtual appliance that connects VMM management server to Azure. Azure Arc resource bridge enables you to represent the SCVMM resources (clouds, VMs, templates etc.) in Azure and do various operations on them.

Architecture

The following image shows the architecture for the Arc-enabled SCVMM:

How is Arc-enabled SCVMM different from Arc-enabled Servers

  • Azure Arc-enabled servers interact on the guest operating system level, with no awareness of the underlying infrastructure fabric and the virtualization platform that they're running on. Since Arc-enabled servers also support bare-metal machines, there might, in fact, not even be a host hypervisor in some cases.
  • Azure Arc-enabled SCVMM is a superset of Arc-enabled servers that extends management capabilities beyond the guest operating system to the VM itself. This provides lifecycle management and CRUD (Create, Read, Update, and Delete) operations on an SCVMM VM. These lifecycle management capabilities are exposed in the Azure portal and look and feel just like a regular Azure VM. Azure Arc-enabled SCVMM also provides guest operating system management, in fact, it uses the same components as Azure Arc-enabled servers.

You have the flexibility to start with either option, or incorporate the other one later without any disruption. With both options, you'll enjoy the same consistent experience.

Supported scenarios

The following scenarios are supported in Azure Arc-enabled SCVMM:

  • SCVMM administrators can connect a VMM instance to Azure and browse the SCVMM virtual machine inventory in Azure.
  • Administrators can use the Azure portal to browse SCVMM inventory and register SCVMM cloud, virtual machines, VM networks, and VM templates into Azure.
  • Administrators can provide app teams/developers fine-grained permissions on those SCVMM resources through Azure RBAC.
  • App teams can use Azure interfaces (portal, CLI, or REST API) to manage the lifecycle of on-premises VMs they use for deploying their applications (CRUD, Start/Stop/Restart).
  • Administrators can install Arc agents on SCVMM VMs at-scale and install corresponding extensions to use Azure management services like Microsoft Defender for Cloud, Azure Update Manager, Azure Monitor, etc.

Note

Azure Arc-enabled SCVMM doesn't support VMware vCenter VMs managed by SCVMM. To onboard VMware VMs to Azure Arc, we recommend you to use Azure Arc-enabled VMware vSphere.

Supported VMM versions

Azure Arc-enabled SCVMM works with VMM 2019 and 2022 versions and supports SCVMM management servers with a maximum of 15,000 VMs.

Resource bridge networking requirements

The following firewall URL exceptions are needed for the Azure Arc resource bridge VM:

Outbound connectivity

The firewall and proxy URLs below must be allowlisted in order to enable communication from the management machine, Appliance VM, and Control Plane IP to the required Arc resource bridge URLs.

Service Port URL Direction Notes
SCVMM management Server 443 URL of the SCVMM management server Appliance VM IP and control plane endpoint need outbound connection. Used by the SCVMM server to communicate with the Appliance VM and the control plane.

Generally, connectivity requirements include these principles:

  • All connections are TCP unless otherwise specified.
  • All HTTP connections use HTTPS and SSL/TLS with officially signed and verifiable certificates.
  • All connections are outbound unless otherwise specified.

To use a proxy, verify that the agents and the machine performing the onboarding process meet the network requirements in this article.
