while working with lots of customers in different Azure projects I often here that they want to minimize and reduce their hardware on prem. or even bane every piece of server from their office locations.
In many cases that isn’t really possible. Mostly there are still applications which become very fuzzy with a latency above 30 ms between service and user.
To resolve that gap and reduce the systems on premises to a minimum and save as much money as possible, I started to place Windows Hyper-V Servers with Storage Spaces in the office were I needed lower latency.
At the end we are able to reduce the needed infrastructure to at least two servers, two switches and one router or firewall. I personally call those pieces of hardware “Cache Zone”. The picture below shows a schematic view.
With that I’m able to place services on prem. and cover them via redundancy in the cloud. Currently I have a list of a few basic services like Domain Controller, File Servers, Print Servers or internal Webservers. For the covering of File Servers you can find my post here.
So how does it look like, first you need to connect your office with your cloud provider, either via VPN, MPLS or with some services via HTTPS or other direct services via the internet. You place one partner for example a Domain Controller on prem. the other ones are placed in the cloud.
That’s nearly everything you need. If you use Windows Server 2016 Datacenter for the host, you have also all licenses you need for the features of the virtual machines like Storage Replication.
As server systems, I currently have some small systems von Secure Guard in my testlab.
