.Net vs SSIS: What should SSIS be used for?

Question

If I have the option of using .Net and can do data transformations just fine in .Net, when would I need SSIS? Is there a certain task

Answer 1

SSIS has many built in ways of doing transformations from different data sources and you can string them together in a way that makes it very customizeable. They have built in optimizations that make them fast.

You can also use .NET to make your own custom transformations to take advantage of the speed and repeatability of an SSIS job.
