Goodness knows there are a lot of other cloud options than Microsoft. If you're tightly coupled with one vendor you're gonna be at their mercy.
For most software deployed on a windows server, there is no compatible OS. There's no real choice.
Or rather, you can use the on-prem license in the cloud, but only on dedicated hardware?
If so, Azure Dedicated Instances would be able to use that form of the license, but why not AWS which also has a dedicated hardware option?
> Azure Hybrid Benefit for Azure only
Isn't that kinda the opposite?
