Data Lake
- A centralized, curated, and secured repository that stores all data, both in its original form and prepared for analysis.
- Enables breaking down data silos and combining different types of analytics to gain insights and guide better business decisions.
Lake Formation
- Simplifies setting up and managing data lakes by defining data sources and applying access and security policies.
- Collects and catalogs data from databases and object storage, moves data into Amazon S3, cleans and classifies data using ML algorithms, and secures access to sensitive data.
- Provides a centralized catalog of data that describes available data sets and their usage.
AWS Glue
- A fully managed extract, transform, and load (ETL) service that prepares and loads data for analytics.
- Discovers data, stores metadata in the AWS Glue Data Catalog, and makes data searchable, queryable, and available for ETL.
- Provides access to data using Apache Spark, PySpark, and Python, and can scale workloads using Ray.
AWS Glue Data Quality
- Measures and monitors data quality of Amazon S3 based data lakes, data warehouses, and other data repositories.
- Automatically computes statistics, recommends quality rules, and monitors and alerts when detecting missing, stale, or bad data.
Amazon Redshift
