Hi,

Has anyone used opnsense azure image: https://marketplace.microsoft.com/en-en/product/virtual-machines/decisosalesbv.opnsense?tab=Overview

I see $0.05/hour software cost that shows up in the azure image (in addition to hardware/infrastructure costs). Will this software cost be static and will it increase based on VM CPU cores or throughput? Can someone who has used it please clarify.

No, it's static. It's just the license fee you have to pay for OPNsense. It doesn't grow with hardware scaling.

Is it really paying OPNsense or is it paying Microsoft? I could see a 50/50 split, but OPNsense better get something.

This is what shows in cost.

Though it shows 8 core hours but I actually charged cost is flat, quite low but it does has some little bit extra than $0.05/hour price mentioned on image. Maybe its Azure marketplace fees/commission or taxes, idk. Will observe for few days to confirm that's the case, if needed will ask Azure support.

We spun up 8 core machine and rate was applied at $0.12 per hour which is different than $0.05 per hour published on the plan. SO it doesn't look like it is flat rate.
