Re: Who can use a powerapp?
Hi @hampshire ,
If you want to use PowerApps, you need to register a Microsoft account and sign in.
Then, you could choose license of PowerApps according to your demands.
PowerApps have three kinds of licences: trial, P1, P2. Different licenses have different functions.
What's more, some Office 365 plans and dynamics plans also include PowerApps for Office 365.
Here's a doc about license for your reference:

To sum up, people who have a microsoft account and choose a license can use PowerApps.
PowerApps can connect with local data source like Sql Server.
Yes, many services of PowerApps run on the Azure cloud.
