Demystifying Microsoft Azure Site Recovery

One of the most common questions we get from managed service providers (MSPs) who are in the process of building a cloud practice in Microsoft Azure is “what is Azure Site Recovery (ASR) and when should I use it?” 

Let’s review this important Azure service from Microsoft and its relevance to MSPs.  

Why does ASR exist? 

Azure Site Recovery (ASR) is Microsoft’s Disaster Recovery-as-a-Service (DRaaS) solution built specifically for Azure workloads. ASR enables companies to recover from catastrophes quickly with minimal downtime. ASR can also be used as a tool to migrate existing servers into Azure from an on-premises environment or migrate workloads between Azure regions and resource groups. 

Who is ASR designed for? 

  • Companies that need to meet specific requirements or regulations for their industry such as ISO 27001 
  • Companies who are sensitive to downtime or want to limit impact from region-specific Azure outages 
  • Companies who wish to migrate current workloads into Azure from an on-premises environment, between Azure regions, or between resource groups 
  • Anyone seeking a complete business continuity and disaster recovery (BCDR) strategy for their business 

When can ASR be used? 

  • Replication of Azure VMs from one Azure region to another 
  • Replication of on-premises VMware VMs, Hyper-V VMs, physical Windows and Linux servers, and Azure Stack VMs to Azure 
  • Replication of on-premises VMware VMs, Hyper-V VMs managed by System Center VMM, and physical servers to a secondary site. 
  • Replication of specific workloads running on a machine that’s supported for replication 

What are some of the key features of ASR? 

  • A simple BCDR solution – ASR is built into Azure and can be managed entirely from within a single location
  • Data Resilience – Data is replicated inside of Azure storage with all the resilience and security provided by Azure
  • RTO and RPO Targets – Manage and meet organizational RTO/RPO targets with continuous replication at intervals as low as 30 seconds for Hyper-V servers
  • Easy and Flexible Failover– Test failover and disaster recovery scenarios without disrupting replication
    • Failovers can also be planned for expected outages with zero-data loss
    • Unplanned failovers can happen with minimal data loss and fail back to your primary site can be done easily when it’s available again 

How do I setup a basic ASR replication?  

Enable replication for an Azure VM  

  • In the Azure portal, click Virtual machines, and select the VM you want to replicate 
  • In Operations, click Disaster recovery 
  • In Configure disaster recovery > Target region select the target region to which you’ll replicate 
  • For this QuickStart, accept the other default settings 
  • Click Enable replication. This starts a job to enable replication for the VM

Verify your settings  

  • After the replication job has finished, you can check the replication status, modify replication settings, and test the deployment 
    • In the VM menu, click Disaster recovery
    • You can verify replication health, the recovery points that have been created, source, and target regions on the map

Clean up resources/stop replication  

  • The VM in the primary region stops replicating when you disable replication for it:  
    • The source replication settings are cleaned up automatically. The Site Recovery extension installed on the VM as part of the replication isn’t removed and must be removed manually. 
    • Site Recovery billing for the VM stops

Stop replication as follows 

  • Select the VM 
  • In Disaster recovery, click Disable Replication

AVD MANAGEMENT

Multi-Cloud and On-Premises Deployment with Azure Stack HCI (Coming Soon)

Deploy Azure Virtual Desktop in Azure and extend the session host VM placement to on-premises and other cloud using Azure Stack HCI. Nerdio Manager automates deployment of session hosts, AVD agent installation, and full integration into the AVD deployment in Azure.

Create a brand new Azure Virtual Desktop environment or allow Nerdio Manager to discover an existing deployment, connecting to existing resources, and manage them.

Deploy Nerdio Manager from Azure Marketplace and configure a new AVD environment with an easy to follow, step-by-step configuration wizard. First group of users can access their AVD desktop in less than 2 hours.

Service providers, system integrators, and consultants can leverage Nerdio Manager’s scripted AVD deployment template. Create complete environments with desktop images, host pools, and auto-scaling in minutes.

Create and manage AVD environments that span Azure regions and subscriptions. Quickly link Vnets and resource groups and manage AVD deployments world-wide from unified portal.

Link multiple Azure tenants under the same Nerdio Manager instance and manage AVD deployments that span Azure AD tenants. User identities and session host VMs can run in separate tenants for maximum flexibilty and security.

Deploy and manage AVD environments that span across sovereign Azure Clouds. Cross-sovereign cloud support allows identity (e.g. users and groups) to be in one Azure Cloud, while session host VMs are in another Azure Cloud.

Management of workspaces, host pools, app groups, RemoteApps & custom RDP settings

Administer every aspect of AVD with Nerdio Manager including workspaces, host pools, application groups, RemoteApp publishing, RDP properties, session time limits, FSLogix, and much, much more. Every Azure service that AVD relies on can be managed with Nerdio Manager.

Deploy and manage AVD session host VMs. Hosts can be created manually or with auto-scaling, deleted on-demand or on a schedule, re-imaged to apply updates, run a scripted action, resized, put into or taken out of drain mode, and more.

Manage user sessions across the entire AVD environment, within a workspace, host pool or on a single host. Monitor session status, disconnect or log off the user, shadow or remote control to provide support, or send user an on-screen message.

End users have the ability to log into Nerdio Manager with their Azure AD credentials and manage their own session, restart their desktop VM, or start a session host if none are started in a host pool. (Ability to resize and re-image own desktop is coming soon.)

Create, link, and manage Azure Files shares including AD domain join. Synchronize Azure Files permissions with host pools, configure quotas, and enable SMB multi-channel. Manage file lock handles and configure Azure Files auto-scaling to increase quota as needed.

Create, link, and manage Azure NetApp Files accounts, capacity pools and volumes. Configure provisioned volume size, monitor usage, and use auto-scaling to automatically adjust volume and capacity pool size to accommodate the needed capacity and latency requirements.

FSLogix configuration can be complex and overwheling, but not with Nerdio Manager. Create one or more FSLogix profiles with all the needed options, point at one or more Azure Files, Azure NetApp Files, or server locations and select from VHDLocations, CloudCache and Azure Blob storage modes.

Multiple identity source profiles can be set up and used automatically on different host pools. Active Directory, Azure AD DS, and Native Azure AD are all supported. Choose the appropriate directory profile when adding a host pool and all VMs will automatically join this directory when being created.

Create a copy of a host pool with all of its settings: auto-scale config, app groups and RemoteApps, MSIX AppAttach, user/group assignments, VM deployment settings, etc. Save time by creating host pool “templates” that can be cloned to any Workspace, Azure region or subscription instead of starting from scratch.

Apply user session time limits at host pool level. Automatically log off disconnected sessions, limit the duration of idle sessions, control empty RemoteApp session behavior and more.

Assign Azure AD users to personal desktops to ensure the user will log into a pre-configured VM. Un-assign personal desktops from users who leave the organization and re-use these VMs for new users.

Pre-configure custom Azure tags for all Azure resources associated with each host pool. Tags can be used for charge-back and cost allocation by host pool.

When creating session hosts using NV-series VMs NVIDIA and AMD GPU drivers are automatically installed.

Move existing host pools from Fall 2019 (Classic) object model to Spring 2020 (ARM) object model. Choose to whether to move or copy user assignments. Existing session hosts are automatically migrated or new ones can be created in the ARM host pool.

Automatically enable and configure AVD integration with Azure monitor. Zero configuration required. Azure Monitor Insights for AVD can be used instead of or in conjunction with Sepago Monitor.
