A company is designing a data lake architecture on AWS. They need to ingest streaming data from IoT devices, store it cost-effectively, and allow data scientists to run ad-hoc SQL queries on the data without provisioning database infrastructure. Which TWO services should be used? (Select TWO)

Answer options:

Amazon Kinesis Data Firehose

Amazon RDS for PostgreSQL

Amazon Athena

Amazon Redshift

AWS Glue DataBrew

Amazon DynamoDB

How to approach this question

Identify the ingestion service for streaming data to S3 (Firehose) and the serverless SQL query engine for S3 (Athena).

Full Answer

Amazon Kinesis Data Firehose is the easiest way to reliably load streaming data into data lakes (S3). Amazon Athena is an interactive query service that makes it easy to analyze data in Amazon S3 using standard SQL without managing any infrastructure.

Common mistakes

Choosing Redshift for simple ad-hoc queries against S3, which is overkill and requires more setup.
