Is Adf Better Than Ssis?

Cloud vs On-Premises. It's clear that in some use cases it's straight forward to choose which tool to use. If your project is going to be fully in the cloud, ADF seems to be the obvious choice. If everything is on-premises, SSIS seems a no-brainer.

Will ADF replace SSIS?

ADF is not just “SSIS in the cloud”. While these are both ETL tools with some amount of shared functionality, they are completely separate products, each with its own strengths and weaknesses. ADF is not a replacement for SSIS.

Is SSIS obsolete?

Despite the arrival of Azure Data Factory, SSIS isn't going away soon. You could even say that the two tools have a friendly rivalry right now. Newer versions of Azure Data Factory include the Integration Runtime, a feature that offers data integration capabilities across different network environments.
