Disaster recovery for Azure IaaS virtual machines using Azure Site Recovery is now generally available.
You can easily replicate and protect IaaS-based applications running on Azure to a different Azure region within a geographical cluster without deploying any additional infrastructure components or software appliances in your subscription. The cross-region DR feature is generally available in all Azure public regions where Site Recovery is available.
To get started, see the Replicate an Azure VM to another Azure region article. For more details, see the blog post.
