https://learn.microsoft.com/en-us/azure/virtual-machines/workloads/oracle/oracle-disaster-recovery#approach-2-site-to-site-vpn
I have VPN site to site configured.

@yasser Mohamed AbdelMoneim Thank you for your post and I apologize for the delayed response!

I see that you are planning for disaster recovery of Oracle on Azure and have questions on VM specifications, license and best practices.

This doc - https://learn.microsoft.com/en-us/azure/virtual-machines/workloads/oracle/oracle-disaster-recovery#approach-2-site-to-site-vpn is not talking about using ASR for performing DR. Azure Site Recovery is application-agnostic as long as environment/VM/physical server meets support requirements. You can review supported operating systems in our support matrix articles. For example - https://learn.microsoft.com/en-us/azure/site-recovery/vmware-physical-azure-support-matrix. It will be on you to select a VM of correct config to setup DR.

You can use ASR also for DR. In that case, the VM with a config closest to the on-prem VM will be selected automatically. You can always edit it post replication.

One thing to note for physical machines is that if you are using ASR then you can’t failback to your physical machines but will rather failback to a VMware VM.

Note: For DR, ask an Oracle expert. I think they use Oracle native tools as ours (ASR) don't work well for Oracle.

As per the below doc , we will use ASR .
https://learn.microsoft.com/en-us/azure/virtual-machines/workloads/oracle/oracle-disaster-recovery#approach-2-site-to-site-vpn
so we will create same environment on Azure and link it with site to site VPN , please confirm the same understanding.

If yes, what is the Azure vm suitable in this case according the below :

There is no mention of ASR in the doc - https://learn.microsoft.com/en-us/azure/virtual-machines/workloads/oracle/oracle-disaster-recovery#approach-2-site-to-site-vpn. The set up used Active-Data Guard.

Also in this doc - https://learn.microsoft.com/en-us/azure/virtual-machines/workloads/oracle/oracle-vm-solutions it is mentioned that if you are planning for HA and DR in Azure, you need to also plan backup strategy as part of DR.

Again I would suggest you to contact an Oracle expert to get appropriate guidance for this requirement.
