Accessing On-Prem SQL Server from Azure without using an On-Prem data gateway in between

Question

Can we access an on-premise SQL Server without using an on-premise Data Gateway from Azure? is there any other work around? like with a compromise in security/protocol? I am doing a POC project and would like to access an on-premise SQL Server from LogicApps without using any data gateway bridge in between...

Answer 1

Just for development, absolutely yes, you can use some tools like ngrok to expose your on-premise SQL Server without any public IP or Domain in internet to create a TCP tunnel for listening the port 1433 of SQL Server, as the section TCP tunnel of ngork document said.

However, it is not stable so that can not be used on production . For a PoC project, I think it's available and good enough. But when you want to deploy it as a stable service, to use Azure VPN Gateway is an only available & stable solution if there is not a public internet address for your on-premise SQL Database.
