Azure Virtual Network (VNet) enables many types of Azure resources, such as Azure Virtual Machines, to securely communicate with each other, the internet, and on-premises networks.
You can create a virtual network in the Azure portal to securely communicate with a Microsoft Azure Synapse SQL endpoint.
Before you connect to a Microsoft Azure Synapse SQL endpoint residing in a virtual network, perform the following prerequisite tasks:
Create a virtual network in Azure.
Add a subnet to the virtual network.
Create a virtual machine.
Create a virtual network rule.
Configure the Microsoft SQL Server database that hosts Microsoft Azure Synapse SQL to read from and write data to Azure storage.
Enable the virtual network for the Microsoft Azure Synapse SQL connection.
