How do I migrate VNET caches to Azure virtual machine scale sets?
1. Create a VNET gateway in the Azure Portal and configure the local gateway IP address on the on-premises gateway.
2. Configure an Azure virtual network site to site VPN connection, using the local gateway IP address and the VNET gateway to connect the VNET caches to the Azure virtual network.
3. Create an availability set or a virtual machine scale set for the VNET caches.
4. Provision the VNET caches on the virtual machine scale sets, using the same IP address range configured in step 1.
5. Configure the security policies as desired and map the required ports between the VNET caches and the workloads.
6. Test the VNET caches for availability and performance.
