Azure Site Recovery and automatic dns resolution

Question

Good morning colleagues, how are you?

On this occasion I wanted to ask you about automatic DNS resolution within the Azure Site Recovery environment.

The situation is as follows: We have 40 servers inside a recovery service vault replicating from EastUS to WestUS and we would need automatic DNS registration in both regions when failing over. That is, the DNS registration is automatic from EastUS to WestUS and from WestUS to EastUS.

The client's DNS are on-premises and I only configured them within the vNet of the subscription.

Could you help me a little with the resolution of these issues please? Thank you very much!

You may use Azure Traffic Manager along with Site Recovery to control the distribution of traffic. Refer:
