Which services are key components of the AWS data lake architecture?

• A. Amazon RDS, AWS CloudFormation, Amazon EC2, AWS Lambda
• B. Amazon S3, AWS Glue, Amazon Athena, and AWS Lake Formation
• C. Amazon Elastic MapReduce, Amazon Redshift, Amazon Aurora
• D. Amazon SageMaker, AWS X-Ray, AWS CloudTrail

Answer: (B)

The correct answer highlights essential components that form the backbone of an AWS data lake architecture. Amazon S3 serves as the foundational storage layer for a data lake, allowing organizations to store vast quantities of structured and unstructured data in a scalable and cost-effective manner. This object storage capability is critical as it provides the necessary flexibility for data ingestion. AWS Glue plays a pivotal role in data cataloging and ETL (Extract, Transform, Load) processes. It automates the preparation of data for analytics, allowing data from various sources to be transformed and made ready for querying. This is vital for managing the complexity of large data sets in a data lake environment. Amazon Athena facilitates serverless querying of data directly in S3 using standard SQL. This allows for rapid, ad-hoc analysis without needing to set up complex infrastructure, making it easier to derive insights directly from the data lake. AWS Lake Formation simplifies the process of setting up a data lake by providing tools to manage data access and security, further streamlining the process of data ingestion and organization. Together, these services create a strong ecosystem for building a comprehensive data lake on AWS capable of supporting diverse analytics workloads and enabling data-driven decision-making across an organization.
