FlowWright runs on top of either Microsoft SQL Server database or on Azure DB. Database schemas for both are pretty similar. Customers who run FlowWright within their own server infrastructure tend to run on SQL Servers. Some tend to run on hosted SQL server instances also.
But, with the Microsoft's Azure cloud infrastructure, Azure DBs are becoming very common place for hosting the FlowWright database. Azure DB has no hardware infrastructure to maintain not even a SQL Server to manage, it's all in the cloud. Azure SQL server instance is fully accessible and functions just like the Microsoft SQL Server instance. One of the other main benefits of running on Azure DB is, Azure is able to monitor the database for performance and recommend database performance improvements, that can be also applied just with a click of a button.
You can also spin up a Microsoft SQL Server Virtual machine and host the database within the SQL server instance. This method gives you your own secure cloud instance of Microsoft SQL Server, but totally managed by you. Performance of the SQL Server instance is totally based on what's configured as resources for the virtual machine. Since its on the cloud, you can always bump up the resources on the virtual machine,
