Disaster Recovery for Azure IaaS applications extends Azure Site Recovery's existing functionality, and further simplifies the on-boarding experience for customers:
Offered "as-a-Service" – You do not need any additional software infrastructure (VMs or appliances) in your Azure subscription to enable this functionality. You avoid all the complexity and cost associated with deploying, monitoring, patching and maintaining any DR infrastructure.
Simplified experience – Enabling cross-region DR for an application is so simple that all you need to do is select the VMs you want to protect, choose a target Azure region, select replication settings and you are good to go.
Application-aware recovery – Whether you are an application owner, disaster recovery admin or a managed service provider, ASR lets you stay in control at all times - you can decide when and how to orchestrate a failover. With support for best-in-class recovery point objective (RPO), recovery time objective (RTO) and ASR's powerful Recovery Plans, your applications can meet the recovery requirements that your business demands.
Non-disruptive DR drills – With ASR's test failover capability, you can easily perform a DR drill anytime without any impact to the primary production workload or to ongoing replication, giving you the confidence that your DR solution will work when you need it.
