Azure Site Recovery Provides Business Continuity

• Azure Site Recovery could prove useful for organizations lacking a good site-to-site disaster recovery solution, or those lacking a secondary site entirely.
• The service is supported only for certain workloads and configurations.
• Storage and network charges for the service could be difficult to predict.

Azure Site Recovery (ASR) is a Microsoft-hosted subscription-based service that helps organizations establish disaster recovery and business continuity. It works between one or more on-premises sites, an on-premises site and Azure, or two Azure regions. ASR is intended for use with physical servers and VMs running certain workloads, so organizations will need to do planning, testing, and deployment work to ensure the service will meet their requirements and perform as needed.

Disaster Recovery as a Service

ASR offers disaster recovery for the VMs or physical servers at one site by replicating disks to a secondary site, or to Azure VMs. When the primary site suffers an outage (such as catastrophic loss of a data center), the organization can fail all required systems over to the secondary site and bring the system back up by using the replicated disks.
