Study Notes

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

A cloud data warehouse that makes it fast, simple, and cost-effective to analyze all data using standard SQL and existing Business Intelligence (BI) tools.
Allows running complex analytic queries against terabytes to petabytes of structured and semi-structured data.
Provides fast performance, scalable storage, and cost-effective pricing.

Amazon Redshift Serverless

Makes it easier to run and scale analytics without managing data warehouse infrastructure.
Automatically provisions and scales data warehouse capacity to deliver fast performance for demanding workloads.
Provides flexible, familiar SQL features in an easy-to-use, zero administration environment.

Amazon Managed Streaming for Apache Kafka (Amazon MSK)

A fully managed service that makes it easy to build and run applications that use Apache Kafka to process streaming data.

AWS Entity Resolution

Uses flexible, configurable ML and rule-based techniques to remove duplicate records, create customer profiles, and personalize experiences across advertising and marketing campaigns.
Can create a unified view of customer interactions by linking recent events, such as ad clicks, cart abandonment, and purchases, into a unique match ID.
