For a Microsoft event on Jamaica I was asked to deliver a session on Azure DR. I believe that seeing is believing so I always tend to use as little slides as possible and just demo the Solution. On a Saturday morning, I started out thinking and drawing out the Infrastructure I would need to pull that off.
I have a SOHO environment, and for Inova Solutions, my employer, I moved everything to the Microsoft Cloud. My Surface Pro3 (i5, 8 GB RAM) will just have to do as my “local datacenter”.
The steps for the Azure Site Recovery are very well explained here https://docs.microsoft.com/en-us/azure/site-recovery/site-recovery-hyper-v-site-to-azure including the screenshots so I will not copy that into this blog. For my “Onprem Datacenter I need a Hyper-V machine, well, Windows 10 has Hyper-V. Download the Azure Site Recovery Provider from the Azure Portal and run it. Bummer.
Apparently, the installer does not see Hyper-V on Windows 10 as Valid to install the ASR Provider. I need a Server 2016 or Server 2012R2 Hyper-V. Lucky for me, both Windows10 Hyper-V and Server 2016 Hyper-V support Nested Hyper-V. To enable Nested Hyper-V you need to download and run a PowerShell script called Enable-NestedVm.ps1 from https://github.com/Microsoft/Virtualization-Documentation/tree/master/hyperv-tools/Nested after which you can test by running Get-NestedVirtStatus.ps1 downloaded from the same repository. In the 1st script I had to confirm that I’d be running the Nested Hyper-V Server with less than 4 GB of memory.
My Nested Hyper-V Server running with 3 GB of memory I need to create some seriously small servers. And, another reason for creating small servers is that I want small disks to replicate. Thanks again Server 2016, we now have Nano Server! Here is a Quick Start Guide for Nano Server https://technet.microsoft.com/en-us/windows-server-docs/get-started/nano-server-quick-start . In no time, I created 2 Nano Servers, Nano1 and Nano 2, each assigned 128 MB of RAM and a 1 GB OS Disk. I successfully installed the ASR Provider and registered the Nested Hyper-V Server with the downloaded Registration file. Within 5 minutes my Server popped up in the Azure Portal and I could select my Nano1 and Nano2 Server to start replicating. And here they go:
And here they are:
I ran a Test Failover just to see if I could complete the whole exercise within 45 minutes, the length of my presentation. The test failover only took about 2 minutes.
Just to demonstrate that with minimal equipment you can demo an Enterprise grade feature like Azure Site Recovery using some neat Technologies. The first build took a bit longer than 45 minutes to figure it all out. Ran the whole thing 3 times now to get comfortable with it doing it on stage, well within 45 minutes J.
