Frequently Asked Questions What are the regions which support Regional Virtual Network? Azure supports Regional Virtual Network in all regions How can my convert my existing Virtual network to Regional Virtual Network?

Yes, using the new VNet-VNet feature your existing VNet can connect to the newly created Regional VNet. For more information refer to this link Do I incur any performance degradation for services running inside a Regional Virtual Network? Virtual network is only a logical boundary, it does not dictate where the deployments in the VNet actually go to. If for some reason, you need services to be in the same Affinity group, you can still do that inside a regional virtual network. During deployment you will have to specify the Affinity group to which the hosted service should be bound to. The only restriction would be, that the Affinity groups should belong to the same region as the Regional Virtual network. If you do not bind your hosted service to an Affinity group, and deploy services directly to the Regional Virtual Network, your deployments will be placed in a scale unit inside the region the Virtual Network is bound to. What does newly announced features (Reserved IP, Internal load balancing and Instance level Public IP) have to do with Regional Virtual Network? The newly announced features mentioned in the question are all managed at a regional level, hence they are only available for deployments going into a Regional Virtual Network. Is there any charge associated with a Regional Virtual Network? No, Regional Virtual Network is an enhancement to the platform, it is not charged.
