    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.
