AWS Lake Formation is a service that makes it easy to set up a secure data lake in days.A data lake is a centralized, curated, and secured repository that stores all your data, both in its original form and prepared for analysis.

Note: While setting up or using each environment of the Lake formation, keep in mind always use ‘fuse-internal-analytics’. For example, while creating a bucket, start bucket name as:

‘fuse-internal-analytics-my-bucket-name’. Similarly follow this approach while creating new, glue job, Database, crawler, Data Catalog and so on.
