Hi there,
as far as I know there is no official support for Azure SQL for the WEBCON BPS databases today. If we implement WEBCON BPS in a customer's own Azure tenant as their private cloud, it would be smart to use Azure SQL, because of the integrated HA features, scalability and low maintenance effort.
WEBCON BPS is very well integrated with Microsoft technology and has great integrations with Microsoft services, i.e. M365. I would strongly appreciate, if support for Azure SQL could be added in near future.
We already tested it and with some workarounds at installation time it works. But we cannot recommend this to our customers if there is no official vendor support. Thanks :-)
