ASR replication from on prem to Azure

Question

I am implementing and disaster recovery or mission critical workload VMs in on premise to Azure. Along with the application VM on premise has a VDI infrastructure. I am planning keep few running instances of AVD VMs with published app and VM on the cloud and peer to ASR vnet. In case, application ASR failover I need to point those users access from AVD allowing application serving traffic from ASR failed VM through AVD. Virtual app and desktop are the only way to access the failed application workload. AVD would not know the IP of ASR workload until it fails over and brings the compute up. Would it be possible to create traffic manager profile with private IP endpoints and point on prem Citrix and AVD to traffic manager thus seamlessly redirect traffic to Azure and allow end user connection to the cloud

Hi @prasantc,

Welcome to Microsoft Q&A Forum, thank you for posting your query here!

Azure Traffic Manager operates on a DNS-based mechanism. For any on-premises VM to be recognized, it must have a public IP and a DNS name to ensure proper resolution.

Similarly, in Azure, the VM setup should include a public IP and a DNS name so that both the on-premises and Azure public IPs can be configured in Traffic Manager using priority routing.

Alternatively, if you want to avoid assigning public IPs to individual VMs, you can:

• Disable the public IP on the VM and use only a private IP.
• Add your vm's in the Load Balancer with a public IP in front of the VMs.

Noe: But the endpoint should have a public DNS not private DNS then only it will work
