You can recover compute resources that are attached with load balancer and application gateway that have IP association.
What You can Recover
-
VM connected to LB with NIC-based association: Recover VMs tied directly to a NIC attached to the Load Balancer.
-
VM/VMSS connected to load balancer through public and private IPs: Recover scenarios for VMs and VMSS connected to a load balancer using public/private IP configurations.
-
App Gateway: Recovery support for applications deployed behind application gateway. This includes:
-
Virtual Machines (VMs)
-
VM Scale Sets (VMSS)
-
App Services
-
Function Apps
-
-
Dependency Recovery: Recovers all necessary dependencies of virtual machines, VMSS, App Services, and Function Apps if they are part of the assembly and the respective resource groups are selected during recovery.
Support Matrix for Load Balancer Recovery
The following table displays load balancer configurtions supported for different recovery types.
| Configuration Type | Same-Region Recovery | Cross-Region Recovery |
|---|---|---|
| VM with NIC-based load balancer | Yes | Yes |
| VM/VMSS with public IP | Yes | Yes |
| VM/VMSS with private IP | Yes | Yes |
| VMSS (Uniform) with public IP | No | No |
Support Matrix for Application Gateway Recovery
The following table displays application gateway configurtions supported for different recovery types.
| Configuration Type | Same-Region Recovery | Cross-Region Recovery |
|---|---|---|
| VM behind App Gateway | Yes | Yes |
| App Service | Yes | Yes |
| Function App | Yes | Yes |
| VMSS(Flexible) with (Public/Private) IP | Yes | Yes |
| VMSS (Uniform) with private IP | Yes | Yes |
| VMSS (Uniform) with public IP | No | No |
| App Gateway with unsupported FQDNs | No | No |
| VMSS (Flexible) behind App Gateway | No | No |
Considerations
Review the following considerations that might affect recovery of load balancer and application gateway:
-
Public IP Management: For resources associated with public IPs, a new public IP will be created and attached to the NIC during recovery.
-
Private IP Management:
-
If you disable the "Retain Private IP ranges" option, private IPs will be dynamically allocated during recovery.
-
If you enable the "Retain Private IP ranges" option, the private IPs will be retained as per the source configuration.
-
-
VMSS with uniform orchestration mode: VMSS with Uniform orchestration mode attached to a load balancer or an application gateway through a public IP is not supported.
-
VMSS with flexible orchestration mode: VMSS with flexible orchestration mode attached to an application gateway is not supported.
-
Application gateway FQDN support:
-
Only application gateway configurations associated with FQDNs of App Services and Function Apps are supported.
-
Any other FQDNs attached to the application gateway are not supported.
