Hi,
If this is the wrong place to post this, please let me know...
I have an application that runs on a medical device that runs SQL Server 2016 as it's data store. We recently added features that allows simple peer to peer data sharing between the devices using MS Sync Framework. My question is what sort of licensing are we required to have in a (for example) 10 system environment. Do we really need 100 (10x10) licenses?
Also, if we expose a restful API from a device and the code behind that API manipulates and returns data from the database, does that also require an SQL license per connection?
Thanks

This is a better question for the Microsoft licensing experts on Microsoft's website, but I believe that SQL Server is licensed per core in most cases, but I think it can be licensed by CAL. And that depends on the edition you have. If you have enterprise edition, it is licensed per core.
If you have the per-core licensing model and have 1 centralized database that all of your applications connect to, you can have as many connections to SQL as you want.
If you have the CAL licensing, you need 1 license per user who connects.
If each of your devices has SQL Server running on it, you will need a license for each machine.
I would recommend contacting Microsoft about licensing to get a more definitive answer.
I would recommend (if possible) to have the database centralized instead of on each device. This will reduce the cost of licensing, reduce the cost of maintenance, and speed up recovery time. Plus it makes upgrades a lot more simple.
The above is all just my opinion on what you should do.
As with all advice you find on a random internet forum - you shouldn't blindly follow it. Always test on a test server to see if there is negative side effects before making changes to live!
I recommend you NEVER run "random code" you found online on any system you care about UNLESS you understand and can verify the code OR you don't care if the code trashes your system.
