You use ASP.NET Core MVC with ADO.NET to develop an application. You implement database sharding for the application by using Azure SQL Database. You establish communication links between the shard databases.

You need to implement a strategy that allows a group of operations that are performed on multiple Azure databases to be rolled back on all databases if any of the operations fail.

Solution:

• Deploy a SQL database instance in an Azure Virtual Machine (VM).

• Establish linked servers to each Azure SQL Database instance from the SQL Server instance in the VM.

• Create a stored procedure in the VM that performs the update operations using a distributed transaction and commits them if successful.

• Run the SQL stored procedure on the SQL Server instance in the VM.
