Replacing S3 data lake with Databricks data lake

Very new to the DataBricks technology

We have an AWS S3 data lake.. everything works fine

we work with Big data (new 7GB every month)

I am exploring DataBricks technology

I wonder if we can build our data lake on databricks

will that be a positive thing consider it is faster? what about the cost?

My question is : Can a data lake in databricks replace AWS S3 data lake? for business needs
