You want to automate the monthly upload of web access log data to an Azure SQL Database. What process should you recommend?

In this scenario, Azure Data Factory is the most appropriate choice for automating the monthly upload of web access log data to an Azure SQL Database. Azure Data Factory is a cloud-based data integration service that allows you to create and schedule data-driven workflows, making it well-suited for this task.

With Azure Data Factory, you can set up a pipeline that includes the necessary data movement activities to automate the upload process. This service enables you to connect to various data sources, transform data if needed, and load it into your Azure SQL Database without manual intervention. You can also easily schedule these tasks to run at specific intervals, such as monthly, which aligns with your requirement.

In contrast, the other choices are not designed for this particular need. Microsoft SQL Server Migration Assistant and Data Migration Assistant are tools primarily used for migrating databases from on-premises SQL Server to Azure or for assessing database compatibility. They are not intended for routine data uploads. AzCopy is a command-line utility optimized for copying blobs or files to and from Azure storage, but it does not provide the automated workflows or transformations that Azure Data Factory offers for data integration tasks.
