Azure Data Factory V2 Or SSIS?

Merrill Aldrich explains the differences between Azure Data Factory V2 and SQL Server Integration Services:

The next consideration is a bit more involved if you are new to data integration. Both of these tools excel at transporting data from place to place, but they have important differences in terms of what you can do to modify the data in transit. As a matter of emphasis, ADF has more features geared toward moving the data than performing any complex transformation along the way. SSIS, on the other hand, was built with a large library of transformations that you can chain together to make elaborate data flows including lookups, matching, splitting data, and more.

The tools also overlap quite a lot. In projects this seems to lead to the question of whether you’ll transform the data “in flight” using Extract Transform Load (ETL), or instead move the data to a destination where it’ll be transformed using Extract Load Transform (ELT).

These are not “pretty much the same thing” and Merrill does a good job of explaining what those differences in design mean for the products.
