Disaster recovery for Azure IaaS virtual machines using ASR

Microsoft today announced the public preview of disaster recovery for Azure IaaS virtual machines. This is basically Azure Site Recovery (ASR) for the Azure-to-Azure scenario. With that, you can replicate Azure virtual machines from one Azure Region to another Azure Region, without deploying any other infrastructure components such as software appliances. Cross-region DR feature is now available in all Azure public regions where ASR is available.

The Azure documentation describes it the following way:

In addition to the inbuilt Azure infrastructure capabilities and features that contribute to a robust and resilient availability strategy for workloads running on Azure VMs, there are a number of reasons why you need to plan for disaster recovery between Azure regions yourself:

  • Your compliance guidelines for specific apps and workloads require a Business continuity and Disaster Recovery (BCDR) strategy.
  • You want the ability to protect and recover Azure VMs based on your business decisions, and not only based on inbuilt Azure functionality.
  • You need to be able to test failover and recovery in accordance with your business and compliance needs, with no impact on production.
  • You need to be able to failover to the recovery region in the event of a disaster and fail back to the original source region seamlessly.

Azure to Azure VM replication using Site Recovery helps you to do all the above.

Azure to Azure Site Recovery Setup

To set this up you have to create an Azure Recovery Vault. This Recovery vault cannot be in the same region as the source virtual machines, because if the region is down, you will not have access to the vault.

Form that you can choose to create a new Replication and select the virtual machines you want to replicate. You can select the virtual machines you want to replicate. At the end you choose the target location and create the needed target resources and start the replication.

This will now allow you to failover you virtual machines to another Azure region.

There are some limitations right now, like no support for managed disks or limited operating system support. Check out the Azure Site Recovery support matrix for replicating from Azure to Azure for more support information.

Azure Site Recovery now allows you to replicate Virtual Machines from:

  • On-premise Hyper-V Servers
  • On-Premise Hyper-V using System Center Virtual Machine Manager
  • On-Premise Physical Servers
  • Virtual Machines from AWS
  • Virtual Machines from another Azure Region

Disaster Recovery using Azure Site Recovery

Nearly a year ago Microsoft released a Disaster Recovery solution called Hyper-V Recovery Manager. This was basically a hosted orchestration engine in Microsoft Azure which allowed you to orchestrate datacenter failovers using the in Hyper-V build in feature called Hyper-V Replica.

In 2014 Microsoft invested a lot of work and time to improve this service and in January 2014 HRM changed the name to Azure Site Recovery (ASR).

  • In January 2014 Microsoft announced GA of the Azure Site Recovery service which allowed you to use it for DR Orchestration between on-premises Hyper-V sites using Hyper-V Replica
  • In July 2014 Microsoft acquired a company called InMage and integrated DR Orchestration between on-premises VMware sites using the InMage solution.
  • In October 2014 Microsoft announced the GA for Azure Site Recovery DR Orchestration between Hyper-V on-premises and Microsoft Azure.

At TechEd Europe, Microsoft announced some new stuff coming in the next couple of months.

  • In November 2014 Microsoft will offer a public preview for Azure Site Recovery using SAN Replication. This allows you to use your existing SAN replication and orchestrate your DR with Microsoft Azure Site Recovery.
  • In 2015 Microsoft will allow you to use Azure Site Recovery to replicate your VMware and physical servers to Microsoft Azure.
  • With Update Rollup 4 for System Center 2012 R2 and Azure Pack, Microsoft integrated Azure Site Recovery as a plan or Add-on property for VM clouds. This allows service providers to offer Azure Site Recovery to customers as an option of a VM Cloud plan or Add-On.

This is just a quick overview about the possibilities you have with Azure Site Recovery. I will cover some advanced scenarios in with a series of blog posts in the next couple of weeks. Until then I would recommend you to watch the session with Michel Lüscher and me at System Center Universe Europe where we talked about the Azure Site Recovery solutions before the TechEd announcements.
