A Microsoft platform for building and publishing apps for Windows devices.
Hello,
Welcome to Microsoft Q&A!
If you want to save files in the cloud, you have different ways to implement it.
First, you could try Microsoft Graph. This is free. With the Microsoft Graph, you could store data on the user's OneDrive. The Microsoft Graph Github sample is a good place where you could start. If you have questions about Microsoft Graph, you could ask another question with microsoft-graph Tag. Or ask with microsoft-graph-api Tag on StackOverflow.
Second, you could try the Azure SQL Database. With Azure SQL Database, you build apps that scale with the pace of your business with managed and intelligent SQL in the cloud. If you have questions about Azure SQL Database, you could ask another question with azure-sql-database Tag.
Also, there are other third party cloud servers and you need to check them by yourself.
Thank you.
