Hi,
My company is looking at moving a couple of servers into Microsoft Azure to test performance and scalability, with a view to it being configured as an extension of our network through ExpressRoute. I was wanting to know if it is possible to configure the Azure Virtual Network with the same IP subnet details as our on prem physical network and have these communicate as if they are a single network?
As an example, we have our on prem network with subnet 192.168.1.0/24. On this network I have several servers, one of which is VM1 which I want to move to Azure. It has an IP of 192.168.1.55. I want to have both the on prem network and my virtual network to have same IP ranges so that when I move VM1 to Azure, it will retain its same IP and will still be accessible as before over the ExpressRoute link. Is this even possible? Or would I need a NAT device sat between the 2 networks? Or would I need to create the Azure Virtual Network with a totally different IP subnet? I'm just trying to get a feel for how Azure can be used for my company in a Hybrid Cloud scenario.
Also to note, we don't use SCVMM onsite so currently do not have any virtual networks
Thanks for any pointers on this
