AWS Lake Formation is a service that allows you to collect data from different databases and object storage, save it to S3 data lake and clean it and classify it with ML algorithms. It builds on the capabilities of AWS Glue and its data is then usable directly through services like Redshift , Athena and EMR.
Data Lake Formation
Lake Formation uses blueprints to identify existing data sources that you want to move into your data lake. Data can be grabbed incrementally or all at once and AWS Lake Formation will take care of user security by creating self-service access by setting up users' access and by tying data access with access control policies within the data catalog instead of with each individual service.
Using the Lake Formation service comes at no charge ( beside the cost of all the services it uses)
