Azure Virtual Networks
Arpio's support for Virtual Networks.
Azure Virtual Networks
Arpio replicates Virtual Networks along with their subnets, address spaces, and peerings.
Virtual Network
Virtual Networks are replicated to the recovery environment along with their address spaces and child subnets.
Translated Attributes
| Attribute | Translation Method |
|---|---|
| DDoS Protection Plan | References to DDoS protection plans are removed in the recovery environment |
Automatic Dependency Selection
The following resources are automatically selected into recovery points when a Virtual Network is selected:
- Subnets within the virtual network
- VNet peerings (when the remote VNet is also selected)
IP Address Renumbering
Virtual networks may optionally be configured to have different address spaces assigned to them in the recovery environment via the arpio-config:renumber tag. This allows for cases where both the primary and recovery networks are connected to the same on-premises network and need to have non-overlapping address spaces.
Renumbering affects the following resources within the virtual network:
- VNet and subnet address spaces
- Private IP addresses on NICs and private endpoints
- Route table address prefixes and next-hop IPs
- DNS zone A/AAAA records
- Load balancer and application gateway backend addresses
Subnet
Subnets are replicated to the recovery environment and retain the same address prefix unless the parent virtual network has been renumbered.
Translated Attributes
| Attribute | Translation Method |
|---|---|
| Network Security Group | Reference translated to recovery NSG |
| Route Table | Reference translated to recovery route table |
| NAT Gateway | Reference translated to recovery NAT Gateway |
Automatic Dependency Selection
The following resources are automatically selected into recovery points when a Subnet is selected:
- The subnet's parent virtual network
- Route tables associated with the subnet
- Network security groups associated with the subnet
- NAT gateways associated with the subnet
Virtual Network Peering
Peerings between VNets in the primary environment are re-established in the recovery environment if both sides of the peering are selected for replication.
