HUB

Hybrid Use Benefit HUB | Azure

I have a number of customers implementing HUB benefit for their IaaS VMs in Azure.  In all cases to date this is a rebuild or new build as part of a migration.  It works very well, if licensed, you should definitely be looking at this option to drive down costs.
